<pre>Again I am not a software developer. I have co-reviewed the drm code with a
colleague (retired kernel device driver developer). We see something odd in
line 429-433 of hsw_audio_codec_enable.
<a href="https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/i915/intel_audio.c">https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/i915/intel_audio.c</a>
What happens if there is an interrupt? Specifically, if interrupted before the
function returns, does initialization actually complete? Users complaints are
"no audio passthrough/bitstreaming". Is there a 1:1 relationship to the ELD
write address?
Apologies if we are way off base here.</pre>
