https://bugzilla.kernel.org/show_bug.cgi?id=205841 --- Comment #5 from Ilia Pavlikhin (owl@xxxxxx) --- I use Lenovo Thinkpad USB-C Dock like this https://support.lenovo.com/lv/en/accessories/acc100348 but not quite. I have complex audio setup: alsa puts sound to pulseaudio, pa to jack and jack puts audio to alsa and to physical output. When I boot to 5.4.2 - jack working unstable - I'll try research this. Also I'll try disable UCSI and return with results. -- You are receiving this mail because: You are watching the assignee of the bug.
