inject silence error

1.12.8 Application crashes when enabling inject silence, when using audio source as microphone USB.. have to remove from config file to be able to start the application again.. I have a convertor that uses microphone usb for my turntable to play through SONOS system, streaming via this app on my windows 11 laptop.. . No biggie.. yet to see a stream drop to my sonos.. using vinyl have once or twice though using other sources (randomly)... However I get round this issue with vinyl by setting listen to this device (microphone usb) through default playback device in windows control panel.. then use the Audio Source default device in the application Great little app.. love to see a systray menu though.. Other request the abilty to hide upnp renders in the conifg file akin to what airupnp can do... Sonos does like to show all speaker that are grouped together. i.e Stereo Pairs.. surround sound setup.. etc.. Airupnp has a handy little config setting where you hide the ones you don't want to use.. https://github.com/philippe44/AirConnect
