Hi, I've got a problem where I need to "simulate" microphone output.
Data will be coming over the network, decoded into PCM and basically needs to be written into the mic - which then other programs can read/record/whatever.
I've been reading up on alsa but information is pretty sparse. The file plugin seemes promising - I was thinking of having a named pipe as "infile" which I could then deliver data to from my application. I can't get it to work however (vlc/audacity just segfault).
Code:
pcm.testing {
type file
slave {
pcm {
type hw
card 0
device 0
}
}
infile "/dev/urandom"
format "raw"
}
Are there any better ways of doing this? Any suggestions on alsa plug-ins (particularly the file plugin)?
