You can't hear desktop sounds because they always use pulseaudio no matter what sound system you select as default. For me pulseaudio plays first sound fine after start, others are corrupt along with sound from all other apps. I'll post hw_params later. Also pulseaudio tends to crash often with this driver so I suppose your problem is the same.
Can confirm that once pulse (on FC9 at least) gets involved it sounds terrible.
I worked out that I had removed a package pulseaudio-esound-compat at some point in the past and never realised that it contains the symlinks that gets Gnome to start the pulse server. Once that was fixed the desktop effects started working but only out of my USB headset... and nothing I can find in the gui lets me do anything about it.
In many cases, the pulse problem comes from the in accurate DMA position calculation. PA is often too aggressively updating buffers.
Thanks, I knew there was a reason I stripped pulse out of this machine when I installed FC9. Is that a bug in pulse or is it something that will improve with the sbxfi driver?
Basically it's a bug of the driver.
mplayer and firefox/flash sound terrible, very tinny and scratchy. This is with the base_rate=48000 option set in modprobe.conf
Do you mean a regression with 48kHz in comparison with 96kHz?
Sorry that was a bit ambiguous, I'd never tried 96kHz. Have just changed base_rate to 96kHz and it performs identically to 48kHz. Pulse mangles the sound in just the same manner at 48kHz or 96kHz.
Ah, so you meant mplayer/flash with PA backend?
While I was poking about in my alsa configuration I noticed that there is no /etc/alsa/cards/SBXFi.conf I think pulse looks for it, get errors shown after running pulseaudio -vv ALSA lib confmisc.c:1286:(snd_func_refer) Unable to find definition 'cards.SBXFi.pcm.surround51.0:CARD=0' Would that make any difference to anything? (Sorry if pulse issues are totally off-topic)
It just tries to non-existing configuration, and you can ignore it.
