NVIDIA GPUs that contain Azalia controllers currently all have 1 controller, each having 4 codecs, each having 1 converter.

I think there's a logic bug in hda_codec.c:purify_inactive_streams(); streams are controller-wide, but purify_inactive_streams() only cleans up the converters a single codec as far as I can tell.

... Below is a quick fix patch. Could you give it a try?

Yes, that seems to work great.

Could you explain more why patch_atihdmi.c mostly calls snd_hda_multi_out_* yet patch_nvhdmi.c and patch_intelhdmi.c mostly call hdmi_*?

Thanks very much.
