Subject: RE: [alsa-devel] [PATCH]Support MCP89 and GT21x hdmi audio

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.

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.
