Expected Behavior

When switch between scenes，music with or without album covers can automatically audio monitoring to my speaker under the right audio monitoring settings.

Current Behavior

After setting the music media source audio monitoring to monitor and output, switch between scenes，music without album covers can automatically audio monitoring to my speaker, but music with album covers audio monitoring cant't. I need to set audio monitoring to monitoring off and reset to monitor and output to fix it, but it will only working on single play, enable loop will cause audio monitoring malfunction on the second loop sometimes.

Steps to Reproduce

1.create two scenes A and B
2.add music media source with album covers to scene A (enable loop if you want to check the other malfunction)
3.setting the music media source audio monitoring to monitor and output, it works
4.switch to scene B and than switch back to scene A
5.audio monitoring isn't working properly
(6.set audio monitoring to monitoring off and reset to monitor and output, and it should working just fine before it enters the next loop)

Anything else we should know?

No response

Start by reproducing the issue in OBS Studio 31.0.0 on Windows 11 using two scenes and a music media source with album covers, first without looping and then with looping enabled. Compare audio monitoring after switching scenes and when the second loop begins. Done means monitoring continues correctly after scene switches and repeated loops without resetting the monitoring setting.
