Sound does not work
Last modified: 2005-08-30 14:06:57 UTC
After installing Beta 3 on my iBook, sound does not work. Modules inserted: snd_powermac snd_pcm snd_timer snd i2c_keywest snd_page_alloc soundcore LOAD_OSS_EMUL_MODULES is set to yes, yet those modules are not inserted. I have to modprobe them by hand.
Created attachment 48159 [details] modprobe.d sound file
Created attachment 48160 [details] /etc/sysconfig/sound
Check /proc/asound/cards. If the model is Tumbler or Snapper, the bug is already fixed (#105448).
miguelduarte:~ # cat /proc/asound/cards 0 [Snapper ]: PMac Snapper - PowerMac Snapper PowerMac Snapper (Dev 38) Sub-frame 0 So it seems, but fixed where?
Oops... Didn't see the bug #... Sorry.
Try kernel-of-the-day (KOTD), ftp://ftp.suse.com/pub/people/mantel/kotd
After reading the bug mentioned above, I still have some doubts... If I modprobe snd-pcm-oss, sound works ok. The problem is that SuSE doesn't insert that module by itself. I have to do it by hand, even checking if "LOAD_OSS_EMUL_MODULES" is set to "yes". Does a new kernel solve this?
Do you mean that the sound works if snd-pcm-oss module is loaded even with the older kernel? Isn't the module loaded after a fresh boot, too? If it's not loaded, then try to boot with runlevel 3, login, and check lsmod whether snd-powermac driver is already loaded at this stage.
With the Beta 3 stock kernel, yast autodetects the sound card, but only snd-powermac is inserted. The snd-pcm-oss module is never loaded, as far as I can tell.
Let me ask again: Do you mean that the sound works if snd-pcm-oss module is loaded even with the older kernel?
Yes. Now I've updated to the KOTD. And I think I messed things up, because now alsasound start doesn't load any modules...
"alsasound start" won't load the alsa modules but only oss-emulation modules. The main ALSA modules are loaded via udev/hotplug stuff. (But you can still run "alsasound restart" to force to load modules.) Anyway, please reboot the system on runlevel 3, and check whether the module is loaded as described above.
After rebooting into runlevel 3: -Alsa modules are not loaded. -Doing a alsasound restart loads them, execept for snd-pcm-oss, although now it seems I have sound even without it (snd-pcm-oss).
The bug with "alsasound restart" was already fixed. Will be available on beta4. The fact that the modules are not loaded at boot implies that it's a udev/hotplug problem. *** This bug has been marked as a duplicate of 113158 ***
