i have two profiles (1) pc monitor and (2) pc monitor + tv
when switching from 1 to 2, windows correctly switches from pc to the tv out (for sound) but no sound is heard. i'm forced to switch back to 1 then 2 again for the tv sound to work properly. any ideas?

I've tried it both ways. By default the switch assigned the correct audio profiles (think it even got weirder when I tried to assign profiles). The issue at the end is that I'm switching to different drivers (realtek vs nvidia). Let me know your thoughts. So far the formula has been to switch back and forth once to get everthing working.

I'll try it out and report back. Thx.

I've been having this issue also, except I can't get my sound back on my TV unless I do a full restart. It started a few days ago, randomly, and it's been driving me crazy. I just updated to the 9.7 beta and will also report back.
