Many thanks for this new patch! Now the xrun problems I reported are gone (great!), the SPDIF volume slider works correctly and SPDIF input basically works again.
There seems to remain one problem with SPDIF input that wasn't there with rc6: With rc6, SPDIF input got out of sync sometimes. Muting+unmuting SPDIF input solved this problem. With the newest driver+last 2 patches, the SPDIF input sound is very distorted. After loading the alsa driver it sounds very 'robotic' (don't know how to describe it :-)) and high frequency components are missing. After muting+unmuting SPDIF input approx. 10 times SPDIF input gets into another state and there are many high frequency distortions. These distortions (not this pure high freq tone, I don't get this anymore) remain whenever I switch on SPDIF input. I didn't manage to get undistorted SPDIF input (which was possible with rc6). Dis-/reconnetcting the SPDIF input cable didn't help either.
Another issue regarding SPDIF: Digital input works sometimes when I reboot, sometimes it doesn't (restarting alsa doesn't help then) and I have to reboot once again (I don't see a pattern why it does/-not work sometimes). SPDIF input always works when I do a soft reboot from win98, i.e. the card seems to be initialized by the win driver somehow (would some /proc/asound dumps help solving this problem?). Do you have similar problems with your card? Maybe that's terratec xfire specific. Anyone out there with a xfire who can report about SPDIF input with this card?
Again, many thanks for your work on this driver!

Hi!
If the SPDIF input worked with rc6 it should work now with this patch, the SPDIF input "Source Rate Converter"-SCB
was muted all the time and that should fixed by now.
I discovered that AC3 almost works but get very easily out of sync in some how (got no solution for this yet)
Restarting the application about ~ 10 times, eg. with xine press PLAY-STOP PLAY-STOP ... until you get
sound.
There was/is actually a ring buffer problem in the cs46xx driver giving this kind of outputs (see my previous mail):
"Dec 8 13:40:16 cactus kernel: ALSA ../alsa-kernel/core/pcm_lib.c:176: BUG: stream = 0, pos = 0x4000, buffer size = 0x4000, period size = 0x200"
That should actually be fixed this patch, I hope it's correct.
Sumary of changes:
- Some volume bug fixes
- SPDIF input fix.
- Clear sample buffer after closing IEC958 stream.
- Ring buffer fix (see my previous mail)
- Some other misses, corrections ....
