Title:
HDMI audio is not working on first dock connection (Dell Precision
3590 + WD19DCS + Ubuntu 24.10).
Status in linux package in Ubuntu:
Expired
Bug description:
(made with ChatGPTs help, everything was tried, as you can see)
Video works, but audio is silent until I physically unplug and
reconnect the dock. After that, HDMI audio plays correctly.
Audio sink (e.g. Philips UHDTV) is visible in ALSA and PipeWire, but
aplay reports set_params:1398: Channels count non available,
indicating the HDMI audio path is present but not properly
initialized.
This issue is not present on older Dell Precision models using the
same dock and OS, so it appears to be a firmware or HDMI-over-
DisplayPort initialization problem specific to newer hardware.
I have:
Fully updated firmware via fwupdmgr
Tested reloading audio drivers, restarting PipeWire,
reinitializing the dock via sysfs — none help
Verified this occurs only on first connection; replug fixes it
every time
Please advise if logs or further hardware info would help.
