Dell XPS 15 9500 - HDMI audio output not working

I have a fresh install of Manjaro on my Dell XPS 9500. I have connect an LG monitor via HDMI (via a USB-C dongle) but it does not show up as an audio output device and the sound continues to only play from the integrated laptop speakers.

It has two video devices: NVIDIA GeForce GTX 1650 TI Mobile & Intel CometLake-H GT2. I have installed the NVIDIA drivers (video-hybrid-intel-nvidia-prime) and uninstalled the video-linux driver.

dmesg shows the following error: snd_hda_codec_hdmi hdaudioC0D2: Monitor plugged-in, Failed to power up codec ret=[-13]

Some system info follows, I’m happy to provide any more info that would be helpful.

Here is the output of inxi -Fxz.

Thanks in advance for any tips!

An note on kernel versions. I’m currently running 5.16.11-2, but I also tried 5.15.25-1, which had the same issue.

This should help you out as is something the particular laptop model family requires.

I found similar a error message to this

snd_hda_codec_hdmi hdaudioC0D2: Monitor plugged-in, Failed to power up codec ret=[-13]

in other discussions on this forum and Arch forum

I suggest you try this to disable HDMI silent_stream

sudo tee /etc/modprobe.d/snd_hda_hdmi.conf <<< 'options snd_hda_codec_hdmi enable_silent_stream=N'
