Its not singing for me.
Problem 1
=========
marimba$ sg audio -c 'cat monkey.au > /dev/dsp'
cat: write error: Cannot allocate memory
marimba$ dmesg | grep ALSA
ALSA /u2/lfs/alsa-driver-0.9.0rc1/include/../alsa-kernel/
core/oss/pcm_oss.c:390: HW_PARAMS failed: -12
marimba$ sg audio -c 'aplay monkey.au'
Playing Sparc Audio 'monkey.au' : Mu-Law, Rate 8012 Hz, Mono
ALSA lib pcm_hw.c:252:

According to gdb, the -ENOMEM is returned from the ioctl at
alsa-lib-0.9.0rc1/src/pcm/pcm_hw.c:250, not the earlier ones
that can also result in the same error message.
I'm using linux-2.2.20, i586-pc-gnu, gcc-2.95.2, libc-2.1.3,
modutils-2.3.17 and a Gravis UltraSound PnP card.
I've tried playing with aplay's -D and -B flags, to no avail.
Suggestions?

Not sure how to proceed further with this. Is there enough here
to see where the bad pointer has come from?
Other minor things
==================
alsa-driver-0.9.0rc1/INSTALL refers to module option 'snd_pcm_voices'
for three UltraSound modules.
This now seems to be called 'snd_pcm_channels' elsewhere.
alsa-driver-0.9.0rc1/INSTALL section "ALSA PCM devices to OSS devices mapping"
/dev/snd/pcmC2D0 -> /dev/dsp2 -> minor 3+32 = 39 ??
Also, top level sound card module names changed from snd-card-<name>
to snd-<name>, but there are still some references to the old
snd-card-<name> under alsa-driver-0.9.0rc1/alsa-kernel/isa/*
I'm wondering whether I'm getting all my module options correctly
recognised, because of such changes. Perhaps I'm getting resource
conflicts - I have not yet registered any soundcard interrupts in
/proc/interrupts. Yet I do seem to get the same irq/dma/ioports as
before.
