I'm having some problems with an ISA Pro Audio Spectrum 16 card on a DEC AlphaPC164LX motherboard. I have configured the kernel (2.1.125) to use both the PAS and its Sound Blaster emulator. (2 audio devices). However, when I attempt to use the PAS I get the following error:
Oct 16 02:49:45 draal kernel: Sound: DMA (output) timed out - IRQ/DRQ config error?
When I attempt to use the SB emulation of the card I get:
Oct 16 02:52:10 draal kernel: Sound: DMA (output) timed out - IRQ/DRQ config error? Oct 16 02:52:10 draal kernel: Sound: Error. Audio interrupt (0) after freeing buffers. Oct 16 02:52:11 draal last message repeated 79 times
The obvious answer is that I've got the IRQ and/or DMA configured wrong...but I don't (I've checked several times, both the SB and PAS are configured properly wrt IRQ/DMA). After playing several files, /proc/interupts reveals:
(0)<root@draal:/root> cat /proc/interrupts 1: 3496 keyboard 4: 2397 + serial 5: 25 soundblaster 8: 670187 timer 10: 0 PAS16 16: 6755 BusLogic BT-958 17: 9279 eth0
Could there be a general problem with ISA interrupts on this board?
thanks, -- Bob
