Sound Card Issues
Hi, I've been running Slackware 10.1 for about two weeks (well haven't been using it every day, or very often at all in fact) and the main reason is because I can't seem to get sound to work. Before with the default 2.4.29 kernel I could install the drivers from realtek, but then when I rebooted I would have to reinstall them. Now I can't even install them, after compiling a 2.6.13 kernel. I still have the 2.4 of course, but I want to use the latest and greatest and 2.6 boots way faster. Here is the output of lspci:

One last piece of information, when booting at the very end I get these messages: FATAL: Module snd_pcm_oss not found FATAL: Module snd_mixer_oss not found This shouldn't matter though right, because I'm using ALSA and not OSS. |
Here's a little checklist I ripped off from a thread here, and have used often since. See if it helps.
1. Check the card is recognised: #lspci | grep Multimedia ... should list your PCI devices, and you should see a multimedia device there somewhere eg. I get: 0000:00:05.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10) 0000:00:0f.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 0000:00:0f.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) The sound card is the first entry 2. Check a kernel module is loading for that card #lsmod | grep snd ... will list all the loaded modules that have anything to do with sound. One of them will be related to the sound card you are using eg. mine is snd_cmipci 3. Add an audio group #groupadd audio 4. Add your user to that group #usermod -G audio username 5. Check / change devuice permissions: #ls -l /dev/audio /dev/dsp /dev/mixer #chown root:audio /dev/audio /dev/dsp /dev/mixer |
worked?

Haven't tried it, but from my pspci output you can already see that it does indeed find my sound card as a multimedia device. I think it has something to do with the kernel, since it was my first time compiling a kernel it's likely I missed something. And as for the audio groups thing, isn't it likely that root will already have access to the sound device?
