Webview apps can't be recorded through audio-source=playback correctly

[Soremwar]

Environment

• OS: Windows 11
• Scrcpy version: 2.7
• Installation method: Windows release
• Device model: Xiaomi Redmi Note 12 23028RA60L
• Android version: 14

Describe the bug

When running with audio source playback it works just fine for a minute, but all of a sudden the sound starts coming from the phone again without any errors in the console. This is limited to a single app running in webview mode, all the other applications seem to work just fine

.\scrcpy.exe --audio-source=playback
scrcpy 2.7 <https://github.com/Genymobile/scrcpy>

It is weird that the whole stacktrace is not printed. Can you find it in adb logcat?
