  • Power supply used | XS-GaN-27W (5V5A)
  • SD card used | Crucial P5 Plus 1G NVME

Steps to reproduce

First-time dietpi user (but experienced on other platforms).
Fresh dietpi install, edited dietpi.txt and used automated install.
Wham! Great job, most everything works out of the gate, but I am lost trying to get HDMI sound working.

What I have:
dietpi-config → Advanced options → Audio options
Sound card : [hw:0,0-plug]
Auto-conversion: On

Alsamixer
Card: Pulseaudio

There is no sound though.

Appreciate any guidance.

Maybe something @MichaIng can help with

Hate to top-post my own query, but I got it working and wanted to share what I did:

pactl get-default-sink   # showed card #2 (es8388), ie., not HDMI
pacmd list-sinks  # get indices of available sinks
pacmd set-default-sink 1  # in my case, hdmi0

and now I can play sound.

Thanks for your efforts with dietpi – I am greatly impressed with system usability & performance on my new Opi 5 max.
