Rasp Pi4 7.2.1 no sound for any games but menu fine

[benmully]

My 7.1 install was working perfectly, upgraded to 7.2.1 and I get menu sound and preview video sound, but starting any game from any system and there is no sound. I have checked that the sound output is on HDMI cable, which is correct. But still no game sounds anymore What am I missing?
