Hi,
Laptop 13 11th Gen Intel Mainboard in Cooler Master Case
running Debian 13/Trixie with Gnome
connected to a Samsung Smart TV via HDMI
Any ideas why sound output via HDMI is silent?
Sound briefly worked a few days ago, but unfortunately I don’t know what changed or how to reproduce that.
TV and HDMI cable are probably ok, as playback via my Ryzen Laptop 13 works.
I do not see any relevant error messages in journal.
Thank you!

Kernel option snd-intel-dspcfg.dsp_driver=3 or snd-intel-dspcfg.dsp_driver=1 did not fix the issue (suggested here in 2023: [RESOLVED] No Audio via HDMI - #15 by WERRY_Brice)
Edit 2: No audio board installed.
Edit 3: Likely duplicate of [TRACKING] Audio over HDMI on Ubuntu not working on 11th gen Intel Framework Audio via HDMI works after waking up from suspend (but is silent after reboot)
