I recently upgraded from 2.1.5-REL to 2.2.2-REL and seem to be having a
problem using my sound card now.
Nov 7 12:19:58 plasma /kernel: gus0 at 0x220 irq 11 drq 1 on isa
Nov 7 12:19:58 plasma /kernel: gus0: <Gravis UltraSound MAX (512k)>
Nov 7 12:19:58 plasma /kernel: gus0: <GUS MAX (CS4231)>
I never had any problems running mpg123 before, but after I upgraded I get
the following messages while using it:
Nov 7 11:49:58 plasma /kernel: isa_dmastart: channel 1 busy
Nov 7 11:50:29 plasma last message repeated 179 times
Nov 7 11:52:30 plasma last message repeated 652 times
The mp3 file does play, though it is very jittery at first. I've tried
recompiling the most recent version of mpg123, but the messages still
appear.
None of the other audio software I've used (RealPlayer, mxv, etc.) gives
me those errors. Nothing else should be using DMA channel 1, as far as I
can tell.
Has anyone else experienced this problem? Should I configure my GUS to use
a different DMA channel? Is there a simple fix I am completely missing?
