No audio through HDMI on Pironman 5

I compared a stock Pi 5 to one in a PIronman 5 case. Through the same HDMI cable I get sound from the stock Pi, but not through PIronman 5 case. Because of this I know for a fact it’s not the speaker or HDMI cable.

I looked through relevant posts and found that the config.txt file needs “dtparam=audio=on” which is set correctly on my system.

Are there any other settings / options that I can fiddle with to make sound work over HDMI?

Thanks!

Jeff

Update: I’m not 100% sure how, but the sound is working. I rebooted a couple times and for some reason it’s working now. Maybe re-saving some config files did the trick, dunno.
