Are you able to regress this to a smaller window? I did do some rework a
while back on the HDA driver to support newer GeForce GPUs' audio HW
better, and this potentially had impact on bitstream pass-through,
although it seemed to work at the time. Commits were:
384a48d ALSA: hda: HDMI: Support codecs with fewer cvts than pins
2def817 ALSA: hda: hdmi_eld_update_pcm_info: update a stream in place
3aaf898 ALSA: hda: Separate generic and non-generic implementations
74b654c ALSA: hda: Virtualize SPDIF out controls
7c93597 ALSA: hda: Allow multple SPDIF controls per codec
