Hi, Because I don't have GT220 card on hand, I didn't test it yet. So I didn't add this card to the patch file. I think you could add it after you test it.
About the warning messages, I don't know why. May be some others can answer.
Thanks Wei. nvpublic

I think this may be relevant to this subject, if not then my apologies.
I've just installed a GT220 card and was able to get audio-over-hdmi working by compiling the snapshot drivers from 20100307 which contain Wei's new code. I further had to patch the driver to recognize my card with:

This seems to work fine when running VDR but if I do anything else like upgrade packages, compile something, or maybe create a bz2, then I start to see _a lot_ of the following in my xine log:
pcm_hw.c: snd_pcm_hw_delay() SNDRV_PCM_IOCTL_DELAY failed.
With the old code this didn't happen. However, my setup was an 8400gs using SPDIF OUT from my mainboard to SPDIF IN on the card. Then using a dvi->hdmi cable into the tv.
Again, I apologize if I'm posting this in the wrong place.
Best regards.
So nobody has any ideas at all? This is turning out to be a big problem and I've discovered it will occur even without anything else happening on the system. (originally I thought you needed to do some other activity.) I've checked with some other devs I know and everyone has said the problem is with alsa so it would seem there is a serious bug somewhere since eventually those errors will happen and the audio will start skipping like crazy.
Please let me know if there's anything I can do within my ability to help.
Could you do strace for ALSA ioctls? At least having the error code might help to identify this issue.
I don't know how but I'm willing to try if you want to tell me how to do it. Please keep in mind, I'm just an end-user -- not a developer or even c coder. The most I've done is run xine in gdb to help supply bug info to those devs.
strace -e trace=open,ioctl <xine>
