Comment 37 for bug 94333

This was a very frustrating problem for my Creative Audigy card. I did an
upgrade to 9.04 from 8.10 AND the problem still existed on Gnome. I then
installed KDE, since my machine was pretty robust. Things started to bog
down for various reasons, so I decided to do a clean install of KUBUNTU
9.04, since I am still in learning/test mode, i.e. nothing to lose really.
So far, the sound issue went away. There is definitely some problem related
to the 8 series kernal update and the carry-over to a 9.04 upgrade.

Just curious if anyone who had this issue was able to test the latest
Jaunty 9.04 release yet and confirm if this issue remains? Please let us
know. Thanks.

Bug description:
Although it is visible, Ubuntu cannot fully configure my sound card.

I have a Soundblaster Live card CT4760, and have also tried an SB Live
Platinum SB0060 card (both use emu10k1 driver) and an older Soundblaster
(using the ens1371 driver). Same behaviour. The machine is running an Intel
D850GB motherboard (without the onboard sound option), with the last
available firmware. The most interesting thing is that the Live Platinum
card had the attached LiveDrive bay, and the headphone out put on it worked.
None of the connections and channels on the PCI card itself worked, yet the
LiveDrive extension was configured as the primary audio device. No "Volume"
or "Master Volume" track was available in the mixer, the primary was just
"Headphone Out".

I have tried a clean installation of Dapper, Edgy and Feisty. All exhibit
the same problem. However, I used the same hardware years ago with either
Warty or Hoary and had no issues. The sound worked out of the box.

Anyways, without further ado, here are the symptoms.

1. The device is listed by lspci

3. dmesg shows some clues

$ dmesg

4. /dev/dsp does NOT exist

5. Nowhere else is the card visible:

$ cat /proc/asound/cards
--- no soundcards ---

$ aplay -l
aplay: device_list:222: no soundcards found...

$ alsamixer
alsamixer: function snd_ctl_open failed for default: No such device

$ sudo invoke-rc.d alsa-utils restart
 * Shutting down ALSA...

[fail]
 * Setting up ALSA...
[ OK ]
invoke-rc.d: initscript alsa-utils, action "restart" failed.

I am happy to provide any more information. I have literally spent weeks
going in circles unable to figure this one out.
