Bug Description
Binary package hint: puredata
Runnig Puredata with the alsa backend outputs very bad sound. Also it only outputs sound if the sound input is disconnected.
This is a link for the resulting sound. This is suposed to be continuous sound changing frequency overtime, the results its a bunch of crackles.

There is some more info about this bug at http://
I supose this is somewhat related to the alsa driver of the SoC
For reference i am using a IGEPv2 Board rev/RC 3

11 years later: is this still an issue?
- is your soundcard supporting full-duplex at all?
- are other applications able to play back sound properly?
- have you tried adjusting the buffersize?
- have you tried using JACK instead of ALSA (or the other way round)?
