Audio quality drop in virtual display

Audio quality drops when using VD. I tried a VD via USB as well as using a USB+ WIFI connection separately between the main scrcpy session and VD. Playing with --audio-output-buffer and --audio-buffer did not help either.

The report names virtual display (VD), separate USB and USB+Wi-Fi connections, and the --audio-output-buffer and --audio-buffer options. Begin by reproducing the quality drop with those setups and comparing the buffer settings; done means identifying the cause and verifying consistent audio quality in the affected VD configurations.
