If you experience audio dropouts, add a line:
Process, priority, SWYH.exe, High
Run, C:\Program Files (x86)\Stream What You Hear\SWYH.exe –streamto:”foobar2000 Renderer (User) [Computer-Name]”
SoundSet, 1, , mute
This raises the Process priority of Stream What You Hear so you will never experience audio pops/clicks/dropouts.
