--------------------------------------------------
I was using "-i alsahw,0,0" but that this just records line levels, not
mixed levels. The output of the digital mixer is different.
This is an .asound.conf file
pcm.mon_mix {
type plug
ttable.0.10 1 # (digital mix left)
ttable.1.11 1 # (digital mix right)
slave.pcm ice1712
}
the alsa utilities (aplay, arecord) understand 'mon_mix', but ecasound
doesn't. I must be doing it wrong, because ecasound should recognize the
mixer.
To see if your getting mixer output, record just the left channel but
mix it to 2 channels. See if the resulting output has both channels.
Mine doesn't.
