I've updated my cyan (Acer Chromebook R11) to kernel 5.4rc7 from Ubuntu's mainline PPA, but the audio is still not working (no audio device visible according to pulseaudio).
Are you aware of something else that still needs upstreaming beside the mentioned https://github.com/torvalds/linux/commit/d5e120422db8808e1c8b1507900ca393a877c58f ? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1609750 Title: Audio not working on Acer Chromebook R11 Status in linux: Confirmed Status in linux package in Ubuntu: In Progress Status in pulseaudio package in Ubuntu: Invalid Bug description: Audio is not working at all on Acer Chromebook R11 (codename CYAN). It's a Intel Braswell platform. snd_hda_intel messages seem normal, but Pulseaudio does not detect sound hardware.
