Problems Using in VR

So I got the SmoredBoard and followed the instructions for using in vr, it is a bit weird but the audio works and I got it to go on my arm (desktop +), but I have two problems, 1: I can't play any sounds, whenever I try to click it just does not play, I can use my computer mouse but not the vr controllers. 2: I can't stop all sounds with OpenVR2Key (Similar to the first just vr two key is not working.)

If anybody knows how to solve my problem I would greatly appreciate it. Thank you.
