[alsa-devel] snd_hda_intel locking up on VIA CX700M2 with VT1708A codec

Hello,

I'm trying to work out what's going wrong with the HDA controller in our VIA CX700M2 board; there's a full bug report at https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3910, but briefly, I'm seeing it lock up and refuse to DMA after long enough transferring audio data.

Does anyone have any ideas that would help me track down this lockup and find a workaround?
