PCM broken in ALSA CVS (on Linux 2.6.3)

PCM broken in ALSA CVS (on Linux 2.6.3)

devfs, gcc-3.2.3]

Hi,

I have just installed the latest ALSA from CVS and
discovered that it has broken PCM playback. This is
what aplay gives me now:

$ aplay /usr/lib/sounds/jungle_exit.wav 
Playing WAVE '/usr/lib/sounds/jungle_exit.wav' :
Signed 16 bit Little Endian, Rate 22050 Hz, Stereo
ALSA lib pcm_params.c:2096:(snd_pcm_hw_refine_slave)
Slave PCM not usable
aplay: set_params:805: Broken configuration for this
PCM: no configurations available

This is with a SB-Live! card.

Also, loading the snd-intel8x0 module for the
motherboard's built-in sound device now gives me these
messages in my kernel log:

Mar  3 21:27:21 twopit kernel: PCI: Setting latency
timer of device 0000:00:1f.5 to 64
Mar  3 21:27:22 twopit kernel: snd-page-alloc:
releasing the used block (type=1, id=0x1
Mar  3 21:27:22 twopit kernel: snd-page-alloc:
releasing the used block (type=1, id=0x101
Mar  3 21:27:22 twopit kernel: ALSA
/home/chris/Programs/alsa/alsa-driver/pci/intel8x0.c:2263:
no playback buffer allocated - aborting measure ac97
clock

It's the last one which worries me, of course... ;-).

Cheers,
Chris

try to unload snd-page-alloc module after stopping ALSA.
alsasound init script doesn't unload snd-page-alloc intentionally.


CVS version is in heavy development right now.
don't expect that everything works as before.
it won't work with 2.2 and 2.4 kernels yet.
