No Audio with USB-C to HDMI Adapter on Fedora 41 (Intel NUC i5-1240P + Samsung S95B)

Hi everyone,

I’m encountering an issue with my Intel NUC i5-1240P and Samsung S95B TV while using USB-C to HDMI adapters (Cable Matters and Dell) to stream Moonlight at 4K 120Hz on Fedora 41.

Here’s the situation:

  • I can achieve 4K 120Hz on the TV, but there’s no audio output at all.
  • Audio works perfectly when using HDMI directly (no adapters involved).
  • The issue isn’t limited to Fedora, audio also doesn’t work on other distro like Arch with the adapters (Maybe doesn’t work well with newer kernel).
  • This doesn’t seem to be a hardware, adapter, or cable issue, as everything works flawlessly on Windows 11 (including 4K 120Hz with VRR) and on Debian 12.

Has anyone faced similar issues, or does anyone have suggestions for fixing the audio problem when using USB-C to HDMI adapters?

Thanks in advance!
