Public bug reported:
Hello,
The external mic on my machine doesn't seem to work. If I crank up the
mic volume all the way to 100% or over, I can hear some noise, but
nothing more. I noticed that there are several bugs reported for this
particular sound codec (Conexant CX20549 (Venice)), but none of them
seems to be about the external mic. So I'm reporting this new bug. By
the way, I'm pretty sure the microphone itself works fine, as I used it
before without any problems.
