Recording on SB Live line-in

[Georgina Joyce]

Hi

Use a capitalised 'R' with the line value.  And aumix calls capture 'input gain', thus you'd need something like:

aumix -l 65
aumix -l R 
aumix -i 65

You're supposed to include all those commands in one string, however, I have difficulty in getting the 'R' to move from the mic to line.  But by using the -q switch, you can see what is listed for playback and what is listed for recording.
