[Alsa-user] ALSA UCM: Per-channel volume mixer controls?

[Joshua L. <jo...@dr...>]

Hello all,

I am attempting to write some ALSA use case configuration for a device
using a TAS6424 audio amplifier.
The Linux driver for this amplifier exposes a dual-channel PCM sink.
There are four physical output channels - two for each input channel.

Each output channel's volume can be set with a dedicated ALSA mixer control:
- TAS6424 Speaker Driver CH1 Playback Volume
- TAS6424 Speaker Driver CH2 Playback Volume
- TAS6424 Speaker Driver CH3 Playback Volume
- TAS6424 Speaker Driver CH4 Playback Volume

How can I tell ALSA UCM to set all of these channels when changing the
volume? As far as I can tell, I can only set a single PlaybackVolume
channel.

At a minimum, I need to set all the channel volumes together.
If I can also set each individually by describing which logical stereo
channels map to which output channels, that would be a nice bonus.

This is what I have so far, acting on CH2 alone:

SectionDevice."Speaker" {
  Comment "Speakers"

  Value {
    PlaybackPCM "hw:''${CardId},0"
    PlaybackRate 48000
    PlaybackChannels 2
    PlaybackVolume "TAS6424 Speaker Driver CH2 Playback Volume"
  }
}

Thanks,
Josh

[Alsa-user] Increase buffer size

[Andrew P. <and...@gm...>]

Hi ALSA peeps

I need to increase the buffer size ALSA is using, in order to work around a
problem with my USB audio device, which appears to be caused by something
on my Raspberry Pi. I get occasional pauses in the sound output, which I'm
hoping are just buffer underruns. They sort themselves out once the audio
has been playing for something like 20 seconds.

All my attempts so far to use various conbinations of 'periods'
'period_size' and 'buffer_size' have failed. I'm starting with the
following base asound.conf, which does work:

pcm.ufo202 {
    type hw
    card 1
}

ctl.ufo202 {
    type hw
    card 1
}

How can I get a nice big audio buffer for this device?

Thanks

Andrew.

[Alsa-user] Trying to record stereo mix on ALC892 HDA

[Vampire F. <vam...@va...>]

Howdy! I am trying to get a livestreaming setup where I can hear my 
microphone and line in at the output (zero latency monitoring) and also 
record the stereo mix (record what I hear). I have achieved this on 
Windows, so I know the hardware can do it, and now I'm trying to achieve 
this on linux. When I configure it on windows, the stereo mix appears as 
an extra input.

I've managed to get the monitoring to work, but can't manage to record 
the stereo mix.

I've tried various combinations of flags in the hint file, sometimes I 
can see Stereo Mix as the source for the two DACs, and sometimes not. 
When I select it, there is no signal coming in, even though I'm playing 
some sounds.

I am not sure what to try next. I don't understand what pins are, I've 
tried hda-analyzer and it's not clear to me what flags I need to set. 
Maybe I can take the config from windows and copy it to linux somehow?

Is there a driver flag that creates the stereo mix as an extra input?

I don't want to use software options like using the pulseaudio monitor 
source, because that wouldn't have the mic mixed in, and I want to 
monitor the mic volume relative to the desktop volume, essentially to 
record what I hear exactly as I hear it.

Thanks in advance!

[Alsa-user] Microphone muted when level is set below 8%

[Andrea V. <and...@un...>]

Hi,
  (I am new to the list, not native English speaker and not an expert, so I
apologize for any error or misunderstanding; if this is not the correct
list for my problem thank you for pointing me to the right support list, or
so)

With my ASUS Expertbook laptop, I need to record sound in a very loud room,
so I need to turn down the mic volume, and I do that by the command

amixer -D default set Capture N%

which works fine when N is >=8, but it seems 8% is a threshold because if I
set it at 7% or below, nothing (absolutely nothing) is recorded.

Is there any explanation for that, or any way to troubleshoot the problem?
Unfortunately, 8% is still too high for my use case.

Many thanks in advance for your help!
Best regards
Andrea

[Alsa-user] how to play multiple audio in multithreading with ALSA

[target <si...@16...>]

I am using `alsa-lib-1.2.9` in my embedded Linux system, and now I want to play multiple audio from different threads, so I googled internet (I am NOT familiar with ALSA) and found I can use `dmix`.


Here is the main part of my `/etc/asound.conf` in the board.
```
pcm.!default
{
        type asym
        playback.pcm "play_softvol"
        capture.pcm "cap_chn0"
}


pcm.play_softvol {
        type softvol
        slave {
                pcm play_chn0
        }


        control {
                name "Speaker Volume"
        }


        min_dB -60.0
        max_dB -10.0
        resolution 50
}


pcm.play_chn0 {
        type plug
        slave {
                pcm dmixer
        }
}


pcm.dmixer {
        type dmix
        ipc_key 77235
        ipc_key_add_uid true
        slave {
                pcm "hw:0,0"
                period_time 0
                period_size 320
                buffer_size 2560
                rate 32000
        }
}


ctl.dmixer {
        type hw
        card 0
}


pcm.cap_chn0 {
        type plug
        slave {
                pcm dsnooper
        }
}


pcm.tloop_cap {
        type plug
        slave.pcm "hw:Loopback,0,0"
}


pcm.dsnooper {
        type dsnoop
        ipc_key 77236
        ipc_key_add_uid true
        slave {
                pcm "hw:0,0"
                channels 4
                rate 16000
        }
        bindings {
                0 0
                1 1
                2 2
                3 3
        }
}


ctl.dsnooper {
        type hw
        card 0
}
```
I think the `default` device is using `play_softvol`->`play_chn0`->`dmix`.
So I tried to play 2 PCM files as follows,
```
#include <stdio.h>
#include <stdlib.h>

            break;
        }


        while(ret = snd_pcm_writei(playback_handle, buffer, frames)<0)
        {
            usleep(2000);
            if (ret == -EPIPE)
            {
                /* EPIPE means underrun */
                fprintf(stderr, "underrun occurred ");
                snd_pcm_prepare(playback_handle);
            }
            else if (ret < 0)
            {
                fprintf(stderr, "error from writei: %s ", snd_strerror(ret));
            }
        }
    }
        free(buffer);
        return NULL;
}


void *play_func2(void *arg)

            if (ret == -EPIPE)
            {
                /* EPIPE means underrun */
                fprintf(stderr, "underrun occurred ");
                snd_pcm_prepare(playback_handle);
            }
            else if (ret < 0)
            {
                fprintf(stderr, "error from writei: %s ", snd_strerror(ret));
            }
        }
    }
        free(buffer);
        return NULL;
}


int main(int argc, char *argv[])
{
    int ret;
    int dir=0;
    snd_pcm_uframes_t periodsize;
    snd_pcm_hw_params_t *hw_params;




    if (argc < 2) {
        printf("error: alsa_play_test [music name] [2nd name] ");
        exit(1);
    }


    //1.
    ret = snd_pcm_open(&playback_handle, "default", SND_PCM_STREAM_PLAYBACK, 0);
    if (ret < 0) {
        perror("snd_pcm_open");
        exit(1);
    }
.......
        ret = pthread_create(&tid, NULL, play_func, argv[1]);
        if (argc > 2)
        ret = pthread_create(&tid2, NULL, play_func2, argv[2]);


        pthread_join(tid, NULL);
        if (argc > 2)
        pthread_join(tid2, NULL);


    snd_pcm_close(playback_handle);


    return 0;
}
```


```
asound_threads 1.pcm 2.pcm
play song 1.pcm and 2.pcm
size = 320
size = 320
```


But it sounds messy, the two PCMs are played in an interleaved way, but the speed is wrong and flittered.  


So in my case, how can I play multiple audios (audio mixing) in multithreading?


thanks，

Hi,

in simple terms, it can be said that ALSA is responsible for the
hardware level and provides the kernel modules/drivers. Pipewire is a
soundserver that works on top of ALSA. I can't comment on pipewire, but
some soundservers provide features, such as resampling or at least one
other soundserver provides kind of a virtual patch bay for real-time
audio applications, but it doesn't provide resampling.

I can't comment much on the audio players mpg123 and cmus, but seemingly
you can use cmus without the need to install a soundserver such as
pipewire. Some GUI applications, at least audacity need mpg123.

$ pacman -Si cmus | grep Optional
Optional Deps   : alsa-lib: for ALSA output plugin support

You seemingly can use cmos by directly connecting to ALSA.

Simplified summary

1. To use the Hardware you need the thing that handles the hardware
level. It's ALSA.

2. A soundserver such as pipewire does provide "features" that aren't
necessarily needed.

3. Apps not necessarily need a soundserver, some can use plain ALSA.

IOW you need an audio app and ALSA, but not necessarily a soundserver.

Some distros don't install apps such as audio players or web browsers at
all.

That one of your installs does default to cmus and another to mpg123 is
comparable to distros that install different web browsers by default.
Firefox, Chromium, Vivaldi, Falkon ...

Some apps are based on other apps or at shared libraries. There are
countless of possible combinations, but ALSA is the base that is quasi
always needed.

Ralf

Once you've read the ALSA article above, you might follow the link in it to
the Wikipedia pipewire article.

ALSA is the lowest level component of the Linux sound system, a part of the
kernel.
Things like pipewire are sound servers that sit on top of ALSA and provide
a greater range of functionality.

I'm now been using 'cmus' for a few months, and very much enjoying that!

Those are different music players.  In general music players use some kind
of lower level sound capability; could be ALSA or pipewire or others.

You don't specify which configuration files you're reviewing that baffle
you, so it's hard to help clear things up.

The answers to the above questions should be more clear after reading the
suggested articles.

I also generally like the Arch Linux Wiki for the breadth of information
provided.  This could be useful:

You might also find these useful

[Alsa-user] Basic information on alsa needed

[Seamus de M. <se...@se...>]

I'm a bit confused about where & how 'alsa' fits in the "sound system" 
on my Linux computers.

I struggled for a long time to get sound working on my computers. I 
finally heard of 'pipewire', and finally I can now play music on my 
systems.

I'm now been using 'cmus' for a few months, and very much enjoying that! 
However, I've been comparing the configuration between two of my Linux 
systems (one has 'cmus' installed, the other uses 'mpg123'), and the 
differences are absolutely baffling to me.

Both systems are Debian-based, using the 'bookworm' release. One is a 
"Raspberry Pi Zero 2W", the other a "Raspberry Pi 3A+". I opted for the 
"Lite" version (aka headless) of the OS as these are lightweight 
computers. The "sound system" consists of a single Bluetooth speaker for 
each system.

Initial questions are these:

1. What role does 'alsa' play on my systems?

2. Is alsa's role determined at all by the installation of 'pipewire'?

3. Why would two identically-installed OS (on the Pi Zero & Pi 3A+; both 
with 'pipewire') have such different sound configurations?

4. Is there any intelligible documentation that discusses these questions?

[Alsa-user] Low volume output on Realtek ACL897 card

[Marco A. <mar...@po...>]

Hello,

I spent some hours trying to find a solution but apparently there is none. Some mini PC models from Beelink (for sure model SER6 and SER7, possibly others) have extremely low signal output from the Realtek ACL897 sound card with standard intel-hda driver, making the audio outputs unusable on Linux. This is also true on a fresh Windows install, unless a driver is installed from the Beelink website.
I would like to understand if this is a common issue affecting all ACL897 cards or if this is related to the specific implementation on these PCs. In case this is instead a problem specific to Beelink units, is there any hope to reverse engineer a fix without support from the manufacturer (which indeed doesn't seem much concerned by the issue) or should I just give up?

Thanks for your feedback,

Marco Asa

The parsing of a config is performed at each PCM plugin code.  In
particular case for chmap, pcm_hw.c, pcm_null.c and pcm_route.c call
_snd_pcm_parse_config_chmaps() helper and deal with the parsed data.

And, in most cases, alsa-lib rather complains (even verbosely) if
something goes wrong in the config file.  But the interpretation of
each config leaf is done in each PCM plugin code, and some might just
ignore the errors.  But that's not a general case.

I understand that debugging the config stuff is sometimes messy,
yeah.  Some more verbose debug output would be helpful, indeed.

Re: [Alsa-user] Help on specifying 'chmap' in asound.conf

[Sergei S. <ste...@li...>]

For that matter, which ALSA source files do the parsing ? From my 
old/distant memories, ALSA is silent about mistakes made by user when 
the user provides various configuration files. So, there must be a way 
to resolve the issue of silent ignoring of user mistakes.

A possible temporary solution would be to "trace" (e.g. by inserting 
diagnostic print statements) parsing of provided by user configuration 
files, and to implement this one has to know where to insert the 
diagnostic print statements, and that's why I'm asking the question.

You need to define a composite array, e.g. pass like
    chmap [ "FL,FR" ]
instead.

For multiple configurations, you can put more items such as
    chmap [ "FC" "FL,FR" "FL,FR,FC,LFE" ]

[Alsa-user] Fwd: Help on specifying 'chmap' in asound.conf

[Xinhui Z. <zxi...@gm...>]

Dear all,

   I am having a question regarding how to specify 'champ' for a
plugin.  I do not see any examples of this. I tried many ways to
specify but failed.

  As indicated by the link below,   I can specify the MAP as a string
array.   Can someone provide one example on how exactly this    [chmap
MAP]  can be specified?

"
pcm.name {
        type cras
    [chmap MAP]     # Provide channel maps; MAP is a string array
}
"
https://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html


I can something like these, but none of these work for me.

chmap LFE
chmap "LFE"
chmap FR,FL,LFE
champ "FR,FL,LFE"

Thanks!

Xinhui,

[Alsa-user] snd-hda-intel stops PC Speaker beeps on Thinkpad T-470

[Martin H. <mo...@bo...>]

Hi,

I have a thinkpad T470 where I need the pc speaker beeps to be
functional.  If I blacklist the snd-hda-intel module everything works
correctly.  I'm able to beep via the beep command with the legacy IOCTL
interface, and with both the pcspkr and snd-pcsp modules loaded via
/dev/input/by-path/platform-pcspkr-event-spkr

However, I've been unable to get the system to beep at all if the
snd-hda-intel module is loaded.  I don't see anything that looks
like a beep volume slider in alsamixer.

I've tried beep_mode=1, power_save=0 and various model= options:

#options snd-hda-intel model=thinkpad
#options snd-hda-intel model=tpt460
#options snd-hda-intel model=lenovo-eapd
#options snd-hda-intel model=tpt470-dock
#options snd-hda-intel model=dual-codecs
#options snd-hda-intel model=tpt470-dock-fix
#options snd-hda-intel model=auto
#options snd-hda-intel model=tpt440

but I haven't found anything that helps.

Any pointers?  alsa-info.txt below.
Thanks,
mh

David, afaik the disconnect option never got implemented on linux. You
might want to get a confirmation from the list though (CCed).

Without checking myself, did you look at the hdspconf tool perhaps?

But what I am really wondering is how to set buffers in alsa config and 
how to have access to the "disconnect" option and leave the unit in 
standalone mode. Any ideas?

Re: [Alsa-user] snd_hdsp missing on raspberrypi pi 5

[David K. <da...@ke...>]

Hey there!

Ok so interface is composed of 52pi PCIe slot and a PCIe to PCI riser. 
When connected a digiface the unit is powered from the PI. For now there 
is no converters plugged-in.

With a multiface I've run into power supply issues even with external 
supply. Tried both powering the unit itself or through the PCI riser.

Steps to reproduce on RPI5 bookworm:

 1. Compile kernel with PCI soundcard support.
 2. install alsa-utils, alsa-tools, alsa-tools-gui and alsa-firmware-loaders
 3. Download and copy firmwares from hdsploader to
    /lib/firmware/hdsploader/ (create directory). Not sure why they were
    missing. Maybe optional to update the firmware.
 4. add dtparam=pciex1 dtparam=pciex1_gen=2 (maybe not necessary) and
    dtoverlay=pcie-32bit-dma to /boot/firmware
    /config.txt
 5. Check output of hdsploader and let me know if something's missing!
 6. Have fun!

Congrats David! About twenty years ago I was getting the HDSP+Multiface
card working under Debian on a PowerPC (Apple G3 Pismo Notenbook) with a
PCMCIA card. Your efforts reminded me of these days.

Ok everything works well after adding the right firmware to 
/lib/firmware/hdsploader! I'am very happy and thank's to the folks 
pointing me in the right direction!
