Since a recent reboot (and quite some preceding uptime) into Linux 6.12.6 and later 6.12.9, my Trixie installation does not show nor use any HDMI audio sinks anymore. Before the reboot, HDMI audio automatically showed up in the volume controls when attaching an HDMI screen; afterwards, only the "onboard" audio sinks keep showing. Please advise on how to debug this.
Basic information about my setup:
- Lenovo ThinkPad T15p Gen3 (Intel Core i7-12700H [Alder Lake], Intel Corporation Alder Lake-P GT2 [Iris Xe Graphics], NVIDIA Corporation GA107M [GeForce RTX 3050 Mobile], Intel Corporation Alder Lake PCH-P High Definition Audio Controller)
- Xorg (haven't switched to Wayland yet)
- pipewire + pipewire-pulse
- Scanning lshw output for HDMI yields:
