With the latest unstable I grabbed this afternoon everything is sounding
pretty good right now!

pulseaudio is now working.

[jason at quad alsa-kernel]$ cat HEAD

I can get hw_params when there is something playing.

cat /proc/asound/card0/pcm0p/sub0/hw_params

access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 96000 (96000/1)
period_size: 2048
buffer_size: 16384

Can't get mplayer to play at the same time as flash in firefox but I
don't really know if I've ever managed to do that under pulse...

Thank you again Takashi,

Jason
