Okay, just for safe keeping here I tested this on mainline 5.1 as well.  Same results.  No audio from any sources.

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

Hi,

1. Use Windows to boot to see if there is no sound?
If there is no sound in Windows, it may be a problem with codec or amp, to be sent back to ASUS for repair.

2. Please turn on the following values with hda-verb (alsa-tool -> hda-verb)
./had-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x35
./had-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x8968  // set PDB floating
./had-verb /dev/snd/hwC0D0 0x5b SET_COEF_INDEX 0x01
./had-verb /dev/snd/hwC0D0 0x5b SET_PROC_COEF 0x8540

Please turn on the sound(mixer), play a song.
If there is a sound. Can Kai-Heng help me get a PATCH file.

Best regards
pshou

Subject: No sound output on Zen AIO 27 Z272SD_Z272SD

Hi,

Zen AIO 27 Z272SD_Z272SD doesn’t have sound output [1].

We’ve tried "model=alc256-asus-aio” but it doesn’t work.

Seems like this platform needs something different than ALC256_FIXUP_ASUS_AIO_GPIO2.
