Hello Parsec team,
The current app lacks a volume slider for the client (host doesn't matter in this case). The only way to lower it is to open volume mixer on windows (or relevant OS) and lower it. Sometimes it has to be done repeatedly if you close the app, which is highly annoying. Please make an option to set the volume within the app as a setting and it should also be changed via the overlay (i prefer not to use the overlay though and would rather put a hard lock volume cap at say 20%).
Best Regards and nifty application! ;)
