Title:
No sound output on Zen AIO 27 Z272SD_Z272SD
Status in linux package in Ubuntu:
Confirmed
Bug description:
I find this to be an issue with current LTS 18.04's latest 4.19
kernel. I tested this on mainline 4.20 and 5.0 kernels as well.
No audio because ALC274 not properly loaded for use, so no audio
output. A related card had a similar bug, which was fixed, and may be
of use in resolving this one:
