My problem is to get four analog independent audio-stream channels: I plan to create a terrible quadro sample with csound, process it by pd and output the result to 4 loudspeakers. The last step (out of my Linux-box) is unclear to me: how can I transform the data to real 4 channel analog sound. Is it doable with two eg. SB cards ? There are roumors some PCI128 cards support 4 channel output ( has anybody got this working ) ?
Or do I have to spend $$$ on a RME-Hammerfall-AEB4-O combo.
Even in the last case which sounds most elegant I am not sure which drivers or pd settings are needed.
Thanks for any help. E.Zipfel
