My card is "Asonic C-Media8738, 4 channel" and mostly works with snd_cmipci driver - it is just that (even on completely unloaded system) the sound is (very annoyingly) skipping. ... ALSA pcm_lib.c:316: BUG: pcmC0D0p:0, pos = 4294918144, buffer size = 16384, period size = 1024

Note that the pos is *always* the same (4294918144 = 0xffff4000 = -16384) which might be important.

This looks like a hardware bug.

It's possible that we can get a valid pointer by reading the register multiple times. Please try the patch below.

Thanks Clemens, that patch seems to have fixed it !
