Any SBLive! card will have 4 outputs with the kernel OSS compatible drivers. Note that the front output may need to be attenuated 12dB (internal analog boost in ac97 codec on the card). SBLive 5.1 cards will have outputs :-)

He needs 4 audio outs from pd, so I reccomended the delta44 soundcard. He asked if it was possible to use a cheap soundcard instead (I presume the soundquality is not that important for this). But I have no idea how well that works.
Anyone have experience having 4 outs (an "adc~ 1 2 3 4" object) on a cheap soundcard (one of those 5.1 cards or something) in pd. Does it work?
Pd is going to run linux.
