So I just reinstalled raspbian bullseye lite and steamlink and everything is working well except audio.

I have HDMI audio working, using 'sudo aplay /usr/share/sounds/alsa/Front_Left.wav' I get audio out through the TV. So it isnt the driver itself.

But as soon as I launch steamlink, zero audio. No menu audio in the steamlink UI prior to streaming, no audio while streaming. Ive tried playing with all kinda of settings, default devices in raspi-config, alsamixer device selection defaults to vc4-hdmi, and my config.txt file has hdmi_drive=2 enabled.

Anyone have a similar issue? can you point me in the right direction?
