Hi there -
I'm struggling to get microphone input into pd from linux. I'm using ALSA, and the planet-ccrma version of Redhat 8.0 on an IBM thinkpad. The main things I don't understand are:
- how do the settings in alsamixer affect how audio comes into PD? (the
main reason I ask is that when I boost the level of the mic and/or line-in in alsamixer, I *hear* the microphone/line audio coming out of the speakers of my PC, but so far I haven't been able to get PD to grab it)
- (relately), can I have the levels of mic/line turned down or even
muted in alsamixer, but still get this audio into PD for processing? I don't actually want the audio to go straight through my system to my speakers (thus I want to turn down/off these levels in alsamixer), but I do want the audio to be available to PD for processing.
- is there any good way to figure out how "-audioindev" devices are
numbered in linux other than trial and error? (in the presence of my above problem, I'm not sure if "-audioindev 1" is any more likely to work than "-audioindev 10" based on the multitude of devices that show up in alsamixer..)
much appreciated! -David Merrill
