Ubuntu 10.04 - dual partition - sound lost on shutdown/reboot

  Date: Feb 11    Category: Unix / Linux / Ubuntu    Views: 463
  

I've been pulling my hair out over this problem.

I'm running Ubuntu 10.04 on a second drive as a separate partition on my PC. The
primary OS is Windows XP Professional.

When I first installed Ubuntu, the version was 9.xx. After upgrading I was able
to get Flash to work, but I did not have audio.

I started playing with alsa when I was researching the problem, and then I lost
alsamixer.

So, I followed the instructions provided by another Ubuntu user, and completely
uninstalled/reinstalled alsa.

After reinstalling it, the alsamixer was back, and I had audio.

Then, I shutdown my system for the night. When I brought the system back up,
there wasn't any audio AND there hasn't been any audio since.

Here are some details about the audio portion of my Ubuntu configuration.

Sound card info:

Is your sound card really an USB device?

My sound card is

0 [ICE1724 ]: ICE1724 - ICEnsemble ICE1724
ICEnsemble ICE1724 at 0xbc00, irq 18

I don't know why a USB device is listed. Could that play a role in the problem.

I added to the modules file snd-ice1724, and when I rebooted the first time
audio was restored. Then, once I shut the system down, there wasn't any sound
anymore.

Here's some additional information:

Have you upgraded to the next Ubie? Try going to the speaker icon at the upper
right and click on sound settings. Click on the hardware tab and see how many
audio devices it see.

Is the sound card on the motherboard or a PCI card? I ask because I had to go in
the BIOS and turn off the onboard sound card to get sound working. I found out
my onboard sound card stopped working by troubleshooting with Puppy Linux, since
it has multiple sound card tool to test the speakers, the first one had went bad
and it was the cure to my problem.
Sometimes it can be hardware...
