Public bug reported:
I cannot set the input sound level on the external input of my Conexant
Venice audio device on my Thinkpad R61i via the codec. (The internal mic
doesn't work at all.)
Steps to reproduce:
1. Plug in an external mic.
2. Fire up an application that allows you to observe input audio levels.
3. Start saying '1 2 1 2 1 2..."
4. Adjust both the INTERNAL mic input level (because of another bug in which
the internal mic controls control the external mic and the external mic
controls control nothing)
5. You will not see any change in the recording level, and you will probably
experience clipping if you are using a headset mic.
The workaround for this is to fire up hda_analyzer. Adjusting val(o) and
val(1) on node 0x1a does the stuff.
Here is the diff from hda_analyzer:
