Can't have audio from PC and headset at the same time

[patent zephyr]

Hello guys. I have a setup of alvr 20.10 on bazzite using the latest steam beta. Previously audio worked out of the box but now I have to switch to it manually from steam settings. I wanna have output both from pc and the headset at the same time. Also ALVR stopped appearing as a recording device in pavucontrol. Any help would be appreciated

Here's my session.json

Is there no way to achieve this without manually setting the sink/source every time?
