I'm running a current kernel and am having problems getting the sound
chipset on his laptop working.  I'm using the csa0 bridge driver with pcm.  

booting verbose shows this;
Nov 29 11:07:19 mongrel /kernel: pcm0: <CS461x PCM Audio> on csa0
Nov 29 11:07:19 mongrel /kernel: ac97: codec id 0x       0
Nov 29 11:07:19 mongrel /kernel: ac97: codec features 5 bit master volume
Nov 29 11:07:19 mongrel /kernel: ac97: dac not ready
Nov 29 11:07:19 mongrel /kernel: pcm: setmap 7d19000, 1000; 0xc09c5000 ->
7d19000
Nov 29 11:07:19 mongrel /kernel: pcm: setmap 7d3f000, 1000; 0xc09cb000 ->
7d3f000

running or cat'ing various sound files to /dev/audio results in no output,
though the machine keeps running.

I tinkered with the various delays in the drivers and managed to get the
verbose dmesg output to look like this...

Nov 30 14:58:13 mongrel /kernel: csa0: <Crystal Semiconductor CS4610/4611
Audio accelerator> irq 11 at device 6.0 on p
ci0
Nov 30 14:58:13 mongrel /kernel: pcm0: <CS461x PCM Audio> on csa0
Nov 30 14:58:13 mongrel /kernel: ac97: codec id 0xfbe0003f
Nov 30 14:58:13 mongrel /kernel: ac97: codec features mic channel,
reserved, tone, simulated stereo, headphone, bass b
oost, 5 bit master volume, 
Nov 30 14:58:13 mongrel /kernel: ac97: dac not ready
Nov 30 14:58:13 mongrel /kernel: pcm: setmap 7d1d000, 1000; 0xc09c9000 ->
7d1d000
Nov 30 14:58:13 mongrel /kernel: pcm: setmap 7d1e000, 1000; 0xc09ca000 ->
7d1e000

stil now sound output.

Any ideas for a next step?
