Strangely, my computer would not play sound from the speakers until I right-click the sound menu on the taskbar, go to spatial sound and click off.

It sounds like you're experiencing issues with spatial sound settings affecting your audio output. Here are a few steps you can take to troubleshoot and potentially resolve the problem:

1. Check Audio Device Settings: Ensure that your audio output device is set correctly in the sound settings. Sometimes, the system may switch to a different output device unexpectedly.
2. Update Audio Drivers: Make sure your audio drivers are up to date. Outdated drivers can cause various sound issues.
3. Disable Spatial Sound: Since disabling spatial sound seems to temporarily fix the issue, you may want to keep it off if you do not need it. You can do this by right-clicking the sound icon in the taskbar, selecting 'Spatial sound', and choosing 'Off'.
4. Check for Conflicting Applications: Sometimes, other applications can interfere with audio settings. Make sure no other audio applications are running that might conflict with your sound settings.
5. Restart Audio Services: You can try restarting the Windows Audio service. Open the Run dialog (Windows + R), type services.msc, find 'Windows Audio', right-click it, and select 'Restart'.
6. Run Troubleshooter: Use the built-in audio troubleshooter. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Playing Audio, and run the troubleshooter.

If the problem persists, consider checking for any Windows updates or seeking further assistance from Microsoft support.
