The options in the rec-arc popup menu don’t affect the bleeding issue. Please try following the recommendations in the FAQ I’ve linked in the previous message:
Please make sure you’re using headphones while you record, otherwise the sound from the speakers will be picked up by the mic, in what is commonly referred to as bleeding. The problem may still occur to a lesser extent if you use open ear headphones and the volume is high, the mic may still pick up the signal coming out of the headphones, so if you’re using open headphones make sure that the listening volume is not too high.
If you’re using a phone headset (i.e. the one with the mic along the cable, with a TRRS 4 pole jack), try using regular headphones instead (i.e. the kind without the mic), so that the device’s builtin mic will be used instead of the headset’s mic.
Also try switching between the available options for the “Mic/input level preset” setting in the Settings box.
If you’re using an external audio interface make sure that the mixer or cabling is configured so that the output from the audio device is not fed back into the device’s input.
