USB headset not working on secondary seat after Windows 10 update

[Sophiasmith]

Hello everyone,

I’m using Aster on Windows 10 to run a dual-seat setup (2 monitors, 2 keyboards, 2 mice, separate user sessions). Everything was working fine until a recent Windows 10 update.

After the update, my USB headset is only detected and working on the main seat. On the secondary seat, the headset is either not recognized or shows up but produces no sound at all. Other audio devices behave the same way.

What I’ve already tried:

Reinstalling Aster and reconfiguring both seats
Updating and rolling back USB audio drivers
Reassigning audio devices in Aster control panel
Plugging the headset into different USB ports

None of these steps fixed the issue.

Has anyone experienced this problem where Windows update breaks per-seat USB audio separation in Aster? Any working solution or workaround would be appreciated.
