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
are using pd with alsa?. try this first:
'pd -rt -alsa inchannels 2' and or set it in your ~/.pdrc
if you are hearing input coming across the speakers then your bottle neck is pd. if this doesn't work you may need to explore setting your audio in devices, yes.
