Hi, I tried setting options snd-hda- intel model=alc255-acer, and it worked for me after a reboot.
Let me know if it works for anyone else On Sat, 22 May, 2021, 13:09 Kreaninw, <1523...@bugs.launchpad.net> wrote: > Tried this again on Ubuntu 21.04.

The computer has been released a couple of months ago and it's Intel Skylake -based with a Sunrise Point -based motherboard. INFO: The problem exists in Ubuntu 15.10 too, only microphone jack detected. Currently using Ubuntu 16.04 for proper hardware support. Alsa reports the audio device to be: Card: HDA Intel PCH Chip: Intel Skylake HDMI The speakers are working fine, but both alsamixer and pavucontrol (Pulseaudio Volume Control) raport the unplugged external microphone connector as the only sound input. I have tried many of the alsa model configurations (options snd-hda- intel model=something) without success, alsa finds only the microphone jack, which works fine when I plug an external microphone in it.
