I just updated the bios to the latest version, but no change :(

> If you get the status where the speaker works (e.g. after Windows clean
reboot), try to take alsa-info.sh snapshot.  Run alsa-> info.sh with
--no-upload option, and save the generated output.  Then, take another
alsa-info.sh snapshot while the speaker > doesn't work.  Compare these two
outputs.  (At best, attach both (compressed) files.)

Alsa_info_works and alsa_info_no_works attached - diff didn't show an
obvious difference between getting sound from the speakers and not getting
sound from the speakers.
