Disable audio instead of aborting

When I execute scrcpy, it prints

scrcpy 2.7 <https://github.com/Genymobile/scrcpy>
error: XDG_RUNTIME_DIR is invalid or not set in the environment.
INFO: ADB device found:

but if I instead call scrcpy --no-audio then it works.

When audio does not work, as above, scrpcy should either suggest to use --no-audio, or even better it should assume that --no-audio was provided and go forward.
