OK - I found out part of my problems - the module "snd-pcm-oss" was not loaded! I don't know why it took me so long to find this out. After loading it, /dev/dsp, /dev/mixer, and all their buddies showed up! Woo! I still am having problems with permissions for some reason, and I haven't figured it out. My research on the web showed me that I'm not the first with this problem: http://lists.debian.org/debian-powerpc/2002/debian-powerpc-200211/msg00304.h tml ... but nobody answered his question. I have a very similar setup as the message in the link above, shown below: # /etc/modules.conf alias char-major-116 snd alias snd-card-0 snd-cs46xx alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss options snd major=116 cards_limit=1 device_mode=0660 options snd-cs46xx index=0 # /etc/devfs/devfsd.conf REGISTER ^sound$ PERMISSIONS root.audio 0660 REGISTER ^sound/.* PERMISSIONS root.audio 0660 REGISTER ^snd$ PERMISSIONS root.audio 0660 REGISTER ^snd/.* PERMISSIONS root.audio 0660 # ls -l /dev/sound crw-rw---- 1 root audio 14, 12 1969-12-31 18:00 adsp crw-rw---- 1 root audio 14, 4 1969-12-31 18:00 audio crw-rw---- 1 root audio 14, 9 1969-12-31 18:00 dmmidi crw-rw---- 1 root audio 14, 3 1969-12-31 18:00 dsp crw-rw---- 1 root audio 14, 2 1969-12-31 18:00 midi crw-rw---- 1 root audio 14, 0 1969-12-31 18:00 mixer $ ls -l /dev/sound (audio-group user issuing) ls: /dev/sound/midi: Permission denied ls: /dev/sound/dmmidi: Permission denied ls: /dev/sound/mixer: Permission denied ls: /dev/sound/dsp: Permission denied ls: /dev/sound/audio: Permission denied ls: /dev/sound/adsp: Permission denied Again, any manual attempt to change ownership of the above to "gweber" or to change the permissions to 0666 were unsuccessful.

Subject: [Alsa-user] UPDATED - Problem with Alsa 0.9.4 with IBM Thinkpad A22e (cs46xx module) Last week I sent out the message below trying to describe my problems with a reinstallation of Debian sid on my laptop. After working it quite a bit more, I THINK it may actually be a devfs problem. I feel like I'm missing something very simple, and am sure I'll be embarrassed I didn't think of it when it's solved! Here are my symptoms: The modules still get the error message(s) first described (see below) and still stay loaded. I am able to use alsamixer and play files with "aplay" as root only but not my audio group-priviledged user (I get Permission Denied messages). I still don't have links like /dev/dsp or /dev/mixer, but I do have a /dev/snd directory that looks like: # ls -l /dev/snd total 0 crw-rw---- 1 root audio 116, 0 1969-12-31 18:00 controlC0 crw-rw---- 1 root audio 116, 32 1969-12-31 18:00 controlC1 crw-rw---- 1 root audio 116, 64 1969-12-31 18:00 controlC2 crw-rw---- 1 root audio 116, 96 1969-12-31 18:00 controlC3 crw-rw---- 1 root audio 116, 128 1969-12-31 18:00 controlC4 crw-rw---- 1 root audio 116, 160 1969-12-31 18:00 controlC5 crw-rw---- 1 root audio 116, 192 1969-12-31 18:00 controlC6 crw-rw---- 1 root audio 116, 224 1969-12-31 18:00 controlC7 crw-rw---- 1 root audio 116, 8 1969-12-31 18:00 midiC0D0 crw-rw---- 1 root audio 116, 24 1969-12-31 18:00 pcmC0D0c crw-rw---- 1 root audio 116, 16 1969-12-31 18:00 pcmC0D0p crw-rw---- 1 root audio 116, 17 1969-12-31 18:00 pcmC0D1p crw-rw---- 1 root audio 116, 18 1969-12-31 18:00 pcmC0D2p crw-rw---- 1 root audio 116, 33 1969-12-31 18:00 timer With all the searching I've done over the last 2-3 weeks, I can't find a list of devices that should be in this directory. Am I missing something (i.e. ./dsp or ./mixer) or is this all I should have in here? All devfs/devfsd threads that I've seen only have talked about adding a couple of MKOLDCOMPAT links (see the end of my previous email) - nothing mentioning /dev/dsp at all. Does /dev/dsp link against one of the pcm entries or something? What am I missing? I do have a /proc/asound/ directory and everything looks to be OK in there AFAIK. Other than that, I still get the cs46xx errors on the module load and as touched above, my "audio" group user can't open a mixer or aplay: $ alsamixer alsamixer: function snd_ctl_open failed for default: Permission denied $ aplay aplay: main:480: audio open error: Permission denied The root user can set the mixer and play sound files fine while the audio group user cannot - even though everything in the /dev directory relating to sound has the "audio" group read/write permissions set (see directory listing above). For the heck of it I tried changing ownership of all sound-related devices in /dev to my user (gweber), but that didn't help either. # groups gweber gweber: gweber disk cdrom audio src video staff oracle Thanks in advance for any help you can offer!!!

Subject: Problem with Alsa 0.9.4 with IBM Thinkpad A22e (cs46xx module) Hello, I have been using Alsa for a couple of years with different Linux installs (primarily Debian unstable) on my home and laptop machines, and for over a year with this particular laptop (IBM Thinkpad A22e) without any major difficulties. I have done quite a few installations on my own and others' machines with the same basic configuration - compiled kernel, Alsa compiled as modules, etc. However, due to a recent harddrive crash on my laptop I was forced to reinstall my system, and that's when I started running into some difficulties. I have not been able to find any relevant help online directly related to this problem, so am turning to this list as a result (BTW - I had been keeping fairly well up-to-date on the alsa drivers (0.9alpha through 0.9.3 I believe), but with the new install I had moved to 0.9.4). What I am now seeing on bootup is: ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:416:cs46xx: failure waiting for FIFO command to complete ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:167:AC'97 read problem (ACSTS_VSTS), codec_index 0, reg = 0x7e ...and when I try to stop and start Alsa manually I get the following: ALSA ../../alsa-kernel/pci/cs46xx/cs46xx_lib.c:416:cs46xx: failure waiting for FIFO command to complete The modules DO stay loaded, but I only get dmmidi and midi00 devices in the /dev/sound directory (no /dev/dsp link or other device entries in /dev/sound). Here are some relevant commands and their output: # lsmod Module Size Used by Not tainted snd-cs46xx 70888 0 snd-pcm 62500 0 [snd-cs46xx] snd-timer 15364 0 [snd-pcm] snd-ac97-codec 40072 0 [snd-cs46xx] snd-page-alloc 5116 0 [snd-cs46xx snd-pcm] snd-rawmidi 14048 0 [snd-cs46xx] snd-seq-device 4288 0 [snd-rawmidi] snd 31524 0 [snd-cs46xx snd-pcm snd-timer snd-ac97-codec snd-rawmidi snd-seq-device] mousedev 4436 1 (autoclean) agpgart 26164 0 (autoclean) (unused) uhci 27356 0 (unused) vfat 10892 1 (autoclean) fat 32920 0 (autoclean) [vfat] fan 1632 0 (unused) thermal 6276 0 (unused) button 2540 0 (unused) processor 8344 0 [thermal] battery 5760 0 (unused) ac 1824 0 (unused) eepro100 20500 1 mii 2496 0 [eepro100] keybdev 2148 0 (unused) usb-storage 121968 0 (unused) scsi_mod 89280 0 [usb-storage] hid 19716 0 (unused) usbcore 65548 1 [uhci usb-storage hid] input 3744 0 [mousedev keybdev hid] # ls -lA /dev/sound total 0 crw-rw---- 1 root audio 14, 9 1969-12-31 18:00 dmmidi crw-rw---- 1 root audio 14, 2 1969-12-31 18:00 midi00 Can anyone please help me resolve this issue?
