How to force hdmi output?

Pi MusicBox
1

Hi,

I am testing a HDMI to audio converter, but it is not working as Raspberry does not “sense” a TV. I have also put “output=hdmi” in the settings.ini, but it doesn’t work.

Is there a way to force the HDMI audio output?

Those convertors generally don’t work when it comes to being automatically detected. Post your musicbox_startup log.

So, should I not consider these HDMI audio adapters?

They’re fine if that’s what you must use. Just remember they are a bit of a hack. Hdmi is supposed to report the formats it can support but these things get that wrong so sometimes don’t work very well. I need to check the code again but from the log it seems like it’s getting the hdmi selection correct. Is this adapter of yours known to work?

I don’t know. I have just bought it and never tested. I suspect it was too cheap.

I will try an external USB audio card. Maybe more reliable. What is your experience about the best audio output?

Thank you! I will stay with the internal audio.
