[FR] Integration of scrcpy 2.0's new native audio forwarding

[electron-spin]

Firstly, thanks to everyone working on this excellent project. If I am wrong on any of my points or this subject has already been brought up, please let me know. I am using the latest v2023.1.1 guiscrcpy Appimage on Fedora 38 Workstation.

The release of scrcpy 2.0 seems to have made sndcpy obsolete, as described here: https://blog.rom1v.com/2023/03/scrcpy-2-0-with-audio/

When I run scrcpy through the terminal, I get native audio forwarding with no extra flags need. However, I am unable to do this through the guiscrcpy application. Is this a problem on my end, or is this a feature that is coming down the pipeline?

Thanks!
