Attached. I run it on kernel without the commit. I hope it is fine.
One note: I use monolitic kernel without CONFIG_MODULES. The script complained about missing /proc/asound/modules and other modules related stuff.

Attached.

Nothing fancy. Direct ALSA. I tested with 'speaker-test -c2 -t wav' during bisect.

You need this to be collected when the problem triggers, right? I will follow up with this.
