[Alsa-user] Newbie: Via EPIA M10k, 2.6.1 kernel: ALSA installation issues

[Jon W. <als...@wh...>]

  I have Gentoo and the 2.6.1-epia kernel running on my Via EPIA M10000. 
ALSA was working just fine, so I wandered off to another part of the 
kernel to get my DVB-T card working properly. A few kernel compiles 
later (to remove fb, ramdisks, and modularise the DVB stuff) I'm back, 
and ALSA has dissappeared.

Dmesg shows no signs of ALSA. Where I used ot get this:

Feb 18 09:56:27 teleputer Advanced Linux Sound Architecture Driver 
Version 0.9.7 (Thu Sep 25 19:16:36 2003 UTC).
Feb 18 09:56:27 teleputer request_module: failed /sbin/modprobe -- 
snd-card-0. error = -16

sample rate.

it works on your machine.

Feb 18 09:56:27 teleputer ALSA device list:
Feb 18 09:56:27 teleputer #0: VIA 8235 at 0xe400, irq 5

I now have nothing. I can run alsasound start, and all the modules 
appear to load properly. I can run alsamixer and set levels, but I don't 
have sound. If I try to play a WAV file with aplay, it errors out:-

teleputer log # aplay /usr/share/sounds/gnibbles/pop.wav
Playing WAVE '/usr/share/sounds/gnibbles/pop.wav' : Unsigned 8 bit, Rate 
8000 Hz, Mono
ALSA lib pcm_hw.c:523: (snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed: 
Input/output error

I thought I'd try compiling ASLA separately from the kernel. I have 
sound card support configured as a module in kernel config, and I've 
removed everthing about ALSA and OSS. When I sebsequently emerge ALSA, 
it fails with:-

<-snip->
make[1]: Entering directory `/usr/src/linux-2.6.1-epia'
Makefile:405: /usr/src/linux-2.6.1-epia/arch/x86/Makefile: No such file 
or directory
make[1]: *** No rule to make target 
`/usr/src/linux-2.6.1-epia/arch/x86/Makefile'. Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.1-epia'
make: *** [compile] Error 2

I don't have a /usr/src/linux-2.6.1-epia/arch/x86 directory. I think it 
should be i386 instead of x86. Am I heading in the right direction? If 
so, please advise how/where I change the package to look in the right 
location. I should add that I'm now using ALSA 1.0.2 as recommended for 
the EPIA boards, where I used to have 0.9.7. Are there any issues with 
1.0.2c and EPIA?

I really don't know where to start troubleshooting this. Any ideas would 
be most welcome.

Cheers,


Jon
