Bug Description
I have working sound as per the uploaded fix for bug 131133 (that is, version 2.6.22-14.10 of linux-backports
I have a microphone plugged into the socket.
If I set 'Input Sound' to 'Mic' in alsamixer, the recording is so faint that I can barely hear it. If I set it to 'Front Mic' the recording is a decent volume but there is also a whining static sound which is very unpleasant. (Note that the meaning of 'Mic' versus 'Front Mic' is entirely opaque to me: it's easy to find suggestions on which settings to twiddle, difficult to find out what they mean.) There is no 'Mic Boost' option.
