Try using DMA channels 1 and 0 (instead of 3 and 0). There seems to be a bug somewhere in newpcm that causes the sound card to sleep on pcmwr, unless the DRQs used are 1 and 0 (I tried various other combinations with no luck). The order is important - 0:1 doesn't work either. I haven't had the time to investigate it further.
