pulseaudio fails with M-Audio Revolution 5.1

[xpaulbettsx]

It appears to be failing at set_format(). I'm using PA 0.9.6 on Ubuntu Gutsy. Revolution cards are a severely broken experience with Pulseaudio, as not only can I not use PA, I can't even use regular ALSA because PA is set as the default ALSA device. Let me know if you need more info

(I added some extra debug messages)

I work with Gutsy and pulse audio. Not problem...

I assume that your soundcard is one of those 24-bit only sound cards, is that right?

Please check whether "aplay -D hw:0 -f cd /dev/urandom" works or produces the same error.

OH, and POSIX shared memory (/dev/shm) is not properly set up on your machine, as it seems.

Recent SVN versions of PulseAudio (in the "lennart" branch) support these sound cards properly.

Commited to trunk.
