Sure, note I'm just forwarding these bugs from Fedora reporters,
more often then not I don't have access to the hardware myself.

I always add a BugLink tag to the bug, so perhaps next time you
can reach out to the reporter directly ? I've forwarded your
request this time.

I also always ask for alsa-info.sh output, so following the BugLink
will also give you access to that.

Regards,

Hans
