Floris,
From what I understand, you can fit only 2 uncompressed audio channels
over a spdif connection. In order to handle more channels, it must be
compressed and then transferred as a data stream, like DTS or AC3.

I guess you'd need to use channels 8 instead of channels 4
Interesting, I don't have that audio filter. Perhaps it isn't

Please,
I'm developing an application that receives many independent audio
streams from networks to be played simultaneously (voice-conferencing).
There is one thread for each network connection that provides the audio
samples.
The trouble here is that since all the streams are suposed to be
