Comment 2 for bug 418002

Okay so I looked over the debugging page, and I have done everything on that page at least once before.

"Is your sound system plugged in and switched on. I spent an hour trying to diagnose a sound issue when the problem was that I had switched off the speakers to answer a phone call and forgot that I had done so."

Yes, that was the first thing I checked.

"From command line: Open a terminal window and launch alsamixer. Then unmute as described above."

I believe I stated in my original post that alsamixer is not working.

"From GUI: This can be done by running something like gnome-alsamixer from a terminal window or navigating to your your Volume Control. Then unmute as described above. Also check that your switches are set correctly - for instance that if you use the analog output the analog switch is set ON or that the digital or S/PDIF switch is set OFF. You can select which tracks/switches are visible in Volume Control (see above) under Edit->Preferences."

First thing I tried.

"Most sound applications output to card0 by default. In some cases, other audio devices (like a USB MIDI Keyboard) might be recognized as a soundcard and take card0, bumping your real soundcard to card1. To see which devices are connected to which cards, do the following:"

triksterx@triksterx-desktop:~$ cat /proc/asound/cards
--- no soundcards ---

As you can see, this is where I start running into a problem. I am constantly running into a "no soundcard" message, even though my lspci output clearly shows that I have an on-board sound card.

"Make sure that all users needing access to the Sound Device can "Use audio devices" in the "User Privileges" tab of users-admin (System->Administration->Users and Groups)."

Second thing I tried.

"Test different "Sound Servers": Go to System > Preferences > Sound ("Multimedia Systems Selector" in earlier editions of Ubuntu). From there, you can test the different options. In some scenarios several different sound servers may be installed, and only one may work. This is probably the origin of the problem if you cannot play audio with xine or rhythmbox, but you can with xmms or helix/realplayer."

Tried it, didn't work.

"If you can get absolutely no sound and you have an onboard sound chip you can try to disable it in the BIOS. This solves the problem is some cases."

No settings in my BIOS for sound chips.

"If you have no sound and you have a regular sound card type "lsmod | grep snd" in the terminal and see if there is more than one card listed. It's possible that you have a motherboard sound chip that is interfering. Add it to the bottom of the blacklist file. For example, sudo nano /etc/modprobe.d/blacklist then add "blacklist snd_via82xx" to the bottom."

I only have a Mobo soundcard. Output of command is nothing.

Since I have filed the bug report I have also tried to upgrade to the latest version of alsa, with no luck.

I did a fresh install of 8.04 Hardy, and the sound works perfectly on that, with no settings changed. Is there really a change so drastic that my well supported card suddenly is no longer supported? I know the drivers are all there, my sound system works, and my soundcard works. It is most definitely a problem with ALSA 1.0.18, so is there a way to revert to the version used in 8.04 Hardy?
