Update: the method I described above doesn’t work in 4.5, but
does work in 4.6.
Working mixerctl for reference:
Code:
record.sel8-i10i11i12=2
outputs.spkr.mute=off
outputs.spkr=255,255
record.mic.mute=off
record.mic=1
record.mic.agc=off
record.line.mute=off
record.line=178,178
record.aux.mute=off
inputs.mic.mute=off
inputs.mic=191
inputs.line.mute=off
inputs.line=191,191
Problem solved.
(Another pleasant surprise: the
old video card works out of the box in 4.6, no configuration needed!)
