Subject:   Soundcard in PC164?
Message-ID:  <8ohi49$2ep$1@ganerc.mips.inka.de>

Are there any particular limitations on soundcards in a PC164?

I've put a Soundblaster PCI64 into the machine, loaded the snd_pcm
and snd_es137x modules:

pcm0: <AudioPCI ES1370> port 0x10100-0x1013f irq 0 at device 6.0 on pci0
pcm0: interrupting at CIA irq 0

Trying to play a piece of sound with mpg123 results in

pcm0: play interrupt timeout, channel dead

I've been told (classification: rumor) that the SB PCI64 and SB PCI128
cards, apparently nee Ensoniq AudioPCI, have a cheap PCI interface that
makes certain assumptions about PCI interrupts that aren't valid on the
PC164 (and some others) and thus will not work at all on that platform.

Any truth to this, or is the above just due to a pcm(4) bug?
