Hey Avid Community.

I'm a noob. I have my system working mostly fine, but I have one persistent problem I haven't been able to figure out yet:

I can't get sound to play out through HDMI, or even to headphones if HDMI is connected.

I have about the simplest system you can have, and two configs are acceptable for how I work:
Laptop > HDMI to monitor > speakers plugged into monitor
Laptop > speakers out (headphones) =parallel with= HDMI

This lets me use a big screen instead of the tiny laptop screen and I have USB for peripherals (mouse, full size keyboard).

But I can only use Pro Tools with the HDMI disconnected; there is no other way to get output. I end up disconnecting everything and using the tiny laptop screen, which makes editing much harder and much less convenient.

Any suggestions?


This is probably overkill for this problem, but here's my setup:
