[alsa-devel] No sound output on Zen AIO 27 Z272SD_Z272SD

[Derek Gordon]

I installed alsa-tools via repo.

I booted the latest 4.18.x kernel from Ubuntu.

root at derek-Zen-AIO-27-Z272SD:/home/derek# hda-verb /dev/snd/hwC0D0 0x20
SET_COEF_INDEX 0x35
nid = 0x20, verb = 0x500, param = 0x35
value = 0x0
root at derek-Zen-AIO-27-Z272SD:/home/derek# hda-verb /dev/snd/hwC0D0 0x20
SET_PROC_COEF 0x8968  // set PDB floating
nid = 0x20, verb = 0x400, param = 0x8968
value = 0x0
root at derek-Zen-AIO-27-Z272SD:/home/derek# hda-verb /dev/snd/hwC0D0 0x5b
SET_COEF_INDEX 0x01
nid = 0x5b, verb = 0x500, param = 0x1
value = 0x0
root at derek-Zen-AIO-27-Z272SD:/home/derek# hda-verb /dev/snd/hwC0D0 0x5b
SET_PROC_COEF 0x8540
nid = 0x5b, verb = 0x400, param = 0x8540
value = 0x0

No audio for Youtube.com, local MP3, or the "test speakers" option in
Ubuntu settings.
