I had an issue where my Index speakers wouldn't detect unless I replugged in breakaway cable after starting up Steam

Going by the info in this reddit https://www.reddit.com/r/ValveIndex/comments/c72pg0/discussion_and_troubleshooting_for_index_hardware/esmjkz4/

I got it fixed
ymmv and its registry editing so don't fuck around with it if you are scared of touching computer things since you can fuck up your pc with regedit etc
