Hi Developers,
I am using an nvidia MCP78 to connect to a Denon 1910 AVR via HDMI.
I was using Kernel 2.6.32.21 and noticed that the initial few seconds of my songs was being chopped off.
After seeing http://www.spinics.net/lists/alsa-devel/msg29408.html I upgraded to 2.6.35.8 (which has that fix in it) and the problem was been reduced considerably.
But it is still occurring to some extent.
So to see if the HDMI was the problem I changed it to coax spdif - no change/same problem.
Now I think it could be mplayer, so I try audacious - no change/same problem.
Now I think it could be the flac file/decoding, so I decode the flac to wav and use aplay - no change/same problem.
The ONLY way I can get the first 0.5seconds of the file to play is by using audacious and then MANUALLY rewinding (by dragging the scroll bar thingy) back to the start... then it will play (on either flac or wav)
Co-incidentally when I do this I get the following error message dumped to console: alsa: snd_pcm_prepare failed: Device or resource busy.
I hope someone can help :)
I am happy to get debug or whatever - just let me know what you need!
