I have a Shure SM7B that is first connected to a Rolls MS111 MicSwitch which I use to turn it on and off. Then from there the signal goes into a Cloudlifter. Then into the Microphone input 1 of the Scarlet 8i6. I route the signal to output to a speaker to hear. On OBS, I have this microphone signal as a separate sound input mono 1+2. I have a music feed using 3+4. Second stream in a row where, the microphone seemed to work all night (with me using the Rolls to shut it on/off) but at the very end just stops working. I can hear the mic through the speaker and I can see the levels in OBS moving as I talk, however no sound to the stream. The audio feed through 3+4 continues to work fine. Also, if I turn the Rolls off/on again the mic returns. Any advice what would be causing this?
