Thanks for the additional details. I am using SteamVR with its built-in standard overlay containing P2A that I can "float" inside the plane. As my setup is different than yours I probably can't help... other than mention what I have noticed with my setup. I was having a similar issue the last several days where I would put P2A in the overlay and then when I attempted (using controller) to set the SND devices in P2A Settings, I could not see the drop down list in the overlay, but it did appear on the 2D desktop. I could set the values I wanted with the mouse in 2D. Sounds similar to your issue. And so I reinstalled just now version 0.0.27N of the EarlyAccess P2A updates... and now it works. So, I have no explanation, other than the reinstall. I can set the values using controller in both a desktop overlay and if I float the P2A overlay. I am not very familiar with the story on the HP Reverb G2 with WMR (I assume this is Windows Mixed Reality), but as I understand it updating Windows 11 to the latest version might make WMR obsolete. Perhaps you or others who use HP Reverb may know more about that. Best, EagleSight

Can you please provide more information on your VR setup? For example, are you using SteamVR? Are you using the SteamVR Desktop overlay or some other overlay software? Any other details that might be relevant?
