Sound gone after reboot

Rogue Jedi X · 09-10-2006, 04:26 PM

Okay. I got the sound working in Kubuntu Dapper (6.06). It was as easy as enabling the Sound System in System Settings. I listened to music, I played some games, fun times for all. Then I felt like playing Sacrifice, so I booted to windows and afterwards, back to Linux. Only this time, no sound again and the Sound System was enabled. Here's my aadebug output:

I would check to make sure that alsautils is enabled to start up by default when you boot.

Okay, that's weird. I told it to start during boot, like you said in System Settings -> System Services, but I couldn't start it. The status keeps saying "not running" even after I click Start or Restart, so I rebooted. Still doesn't run. What gives?

OK, next would you post the output of "lspci"? And also the output of "lsmod" after you try to start it.
Also, look at /dev for something called "dsp". Check your log files such as /var/log/messages and post the output of "dmesg" after you try to start it. Hope that wasn't too much. Cheers.

Not at all. There is in fact a /dev/dsp on my computer. Here's the lspci output:

The lsmod and dmesg outputs are bit long, so here's the pastebin links.

I was looking elsewhere on this forum(I encourage you to too) and I found this: http://www.linuxquestions.org/questi...ics+Inc+CM8738

I noticed he had this module loaded: snd_cmipci

try modprobing it.

EDIT: Make sure your mixer settings are set correctly too.

Rogue Jedi X · 09-11-2006, 07:30 AM

Fixed it! Tried fiddling with alsamixer and muting the Exchange DAC setting seemed to bring the sound back (with full blast, no less. Had the speaker cranked all the way up. Almost had a heart attack). Thanks for your help, Samoth!

Now I just hope it stays this way next time I boot back from Windows.

About the sound out LOUD....it has happened to me.

Just a few hints: dont set your mixer to 100, the sound quality won't be as good as if it is at 70. The command to store mixer settings is "alsactl store" and to restore is "alsactl restore". You could put that in a boot script to make it so the mixers are reset every boot, although it should be automatic.

Hmm...what if I don't have /dev/dsp and instead have /dev/dsp1?

Mithrilhall · 09-12-2006, 11:51 PM

Well I finally got it working again.

I changed this line in /etc/modprobe.d/alsa-base
