Hi, folks
I have sucessfully re-built my kernel to add support for my
Soundblaster Pro card. (An interesting side-effect is that now
my backspace key works!! Go figure..) I was having trouble
getting CD's to play until I changed the permissions on /dev/cdrom
and the driver device it was linked to. I'm now able to play cds
(8-) but no other sounds.
The Sound HOWTO suggests trying cat *.au >/dev/audio as a
test, but all I get is the following error:
debian:~/sounds/sndkit/dsp$ cat /usr/X11R6/lib/tkdesk/sound/metal.au >/dev/audio
bash: /dev/audio: Cannot allocate memory
I've configured for a 4K (4096) buffer. When I run dmesg, here's
what pops up:
Sound error: Couldn't allocate DMA buffer
This is what shows up in the boot messages:
Sound initialization started
<Sound Blaster Pro (3.2)> at 0x240 irq 5 dma 1,5
<Yamaha OPL3 FM> at 0x388
Sound initialization complete
and cat /dev/sndstat shows this:
Sound Driver:3.5.4-960630 (Mon Jan 11 11:44:46 PST 1999 root,

Kernel: Linux debian 2.0.36 #1 Mon Jan 11 11:45:45 PST 1999 i586
Config options: 0
Installed drivers:
Type 1: OPL-2/OPL-3 FM
Type 2: Sound Blaster
Card config:
Sound Blaster at 0x240 irq 5 drq 1,5
OPL-2/OPL-3 FM at 0x388 drq 0

Synth devices:
0: Yamaha OPL-3
Midi devices: NOT ENABLED IN CONFIG
Timers:
0: System clock
Mixers:
0: Sound Blaster
Is there anything else I can try to debug my setup? I'm
running this on a Pentium 133MHz box w/ 32MB of RAM.
/proc/memstat seems to indicate I have plenty of room to spare:
total: used: free: shared: buffers: cached:

MemShared: 28256 kB
Buffers: 660 kB
Cached: 14080 kB
SwapTotal: 89204 kB
SwapFree: 83956 kB
The card works fine for anything I can throw at it if I boot up
in NT, so I'm pretty sure it's not a hardware problem. Oh, and
is there any other way of changing sound config params other
than a complete kernel re-build?
TIA!!
