Comment 36 for bug 107540

I have the same problem as described in the original report except that I must enable (unmute) the "Audigy Analog/Digital Output Jack" switch to get any sound out of the analog 3.5" jacks I have my surround speaker system plugged in to. I believe that I have had this problem ever since I bought this Audigy card, but since I determined the fix experimentally years ago and the libasound state was preserved, I didn't remember until I tried a Karmic Live CD recently.

I've been quite impressed with the integration of sound preferences and mixer controls in Karmic that hide all distinctions between Pulseaudio, ALSA, kernel, and userspace behind an easy to use GUI. When I boot a Live CD, I can completely control both the motherboard sound device and the Audigy card using the standard volume control and preferences, but I get absolutely no sound out of the Audigy until I run alsamixer in a terminal and unmute its "Audigy Analog/Digital Output Jack" control.

Since this is clearly a device-specific problem, but is related to userspace configuration, I'm not sure if it should be classified as a kernel bug or not.
