Bug Description
In Ubuntu there are several bugs that prevent Audigy 2/4 sound cards from being used for audio input. The card I have to test is an Audigy 2 ZS Platinum Pro (which is identical to the Audigy 4 Pro with the exception of the DAC).
1. Input levels are way too low, even when all inputs are set to 100% in alsamixer. There is a thread on the Ubuntu forums here <http://
2. The input "Line In 2" does not work at all within Ubuntu.
3. The inputs are labeled incorrectly; "Line In 1/Mic In", for example, is labeled "Line2" in alsamixer.
I have been informed that a bug report relating to the most important low volume issue has been open upstream since 2004. <https:/
Note: the original reporter indicated the bug was in package 'alsa'; however, that package was not published in Ubuntu.

A patch has been provided upstream but I am unable to get it to compile. If someone else could take a whack at it, that would be great. (Please?) I'd be more than happy to act as a liaison between the Ubuntu community and the ALSA patch provider with regards to this issue.
Also, the patch appears to be incomplete, as it only addresses one revision of the Audigy2. You may therefore need to manually patch your sources if, like me, you don't own the revision that this patch addresses. Fortunately, it is a single line add, though I don't know if it's portable throughout the entire Audigy2 series.
