I have a RPI4 running a website (local http server with lighthttpd) and I am want to play a sound (wav file) when an icon.
The sound has to be played through HDMI. Monitor supports sound via HDMI.
I set the Sound Setting in DietPi config to HDMI etc.
No sound.
When I try to play the wav file (which is played in the website) on the console I get these messages:
aplay -vv fanfare.wav
Playing WAVE ‘fanfare.wav’ : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: set\_params:1343: Sample format non available
Available formats:
- IEC958\_SUBFRAME\_LE
It seems that the file cannot to be played.
Im never worked with sound on the raspi. Any suggestions?

Try to enable the auto-conversion plugin via `dietpi-config` audio options. The sound card has limited native audio format support. The auto-conversion plugin does the conversion to nearest supported format, when needed. I’m more and more convinced that we should enable this by default.

I tried it. It does not help.
Any other options?

Hello.
I think I have some thing I need to check on.
I am using a sound bar with the pi plug into a hdmi ARC port.
Maybe the ARC is causingf issues for the OS.
I will try to find a non ARC port and test it out

No sound on hdmi, but headphone jack works
Im on a fresh install of dietpi latest with LXDE
With or without auto conversion doesnt seem to make a difference
