Comment 7 for bug 53448

I have tested in Dapper and Feisty.

Sound card: SBLive! Value [CT4832]
$ lspci | grep "Creative Labs"
0000:00:0f.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 06)
0000:00:0f.1 Input device controller: Creative Labs SB Live! MIDI/Game Port (rev 06)

In Dapper:

Patch: launch gnome-alsamixer. Uncheck all recs except your choise of input.
After that the sound recorder will automatically switch to right input when you start recording (althought sometimes when two rec chosen and then recorded, and then one rec is chosen, it can not choose the right input). On the other hand, I could only record microphone when rec checked for Capture (and "Record from input: Capture" in sound recorder). It happened a few times, after that I lost ability to record, or strictly speaking, recording became is very low.
Different mixers are not well synced. When rec is checked in gnome-alsamixer, Capture and AC97 sliders affect in line out 1 when I talk to microphone.

In Feisty:

Recording second time resets input to be AC97. I can not play my recordings by the sound recorder.
I can record by audacity, if rec is checked for capture in gnome-alsamixer. Playing with Microphone, Capture, and AC97 settings affects in line out 1 when I talk to microphone.

Very odd thing is that the recording ability seems to change at times. I thought in the beginning that it would be enough adjust microphone setting in a mixed and choose "record from input: Microphone" in the Sound Recorder to be able to record from microphone. This is little bit too difficult for an end used...
