Audio reverses speakers randomly

I use SoundBlaster Audigy FX configured as 5.1 surround sound running the latest driver. Randomly during any gameplay, the sound will go quiet for a msec then come back reversed. However, if I alt/tab to the desktop, select the SoundBlaster taskbar app and select the speaker config, I can test the individual speakers (see attached) and the sound comes out of the correct speaker. However, the sound is still reversed in the game until I actually reboot the PC. Even if I quit the game and start a different one, the sound's reversed in that one too. Only after a reboot will the sound come back normal.

Any ideas of what's going on?

Instead of rebooting the computer, you could try restarting the audio services. Obviously, this is not a long-term solution, but it might help with diagnostics.
To restart the audio services, open services.msc and, under Name, find :

• Windows Audio - restart the service.
• Windows Audio Endpoint Builder - restart the service.
• Remote Procedure Call (RPC) - restart the service.

You may want to restart each Service, one at a time, then test your audio. That would help pin-point a particular service.

Let us know if restarting these Services alters anything.

If that does not work, you may want to run the Windows 11 Audio Troubleshooter.

Thanks. I will try this the next time the audio switches.
