Describe the Bug

Hi,

I recently updated Sunshine (May 31th version) and my audio is cracking everytime I start a game in moonlight.

I noticed that the output device is switching to 24 bits sound everytime i start a game but moonlight on my TV is using 16 bits LCPM as output.

To fix the issue I simply switch the output device to 16 bits 48000 and I have no more cracking sound.

Is it possible to have the choice in Sunshine GUI to force to use 16 bits audio? (Other than switching the default device to 16 bits?)

Expected Behavior

Have a settings in the GUI
