Audio Bug

Have you guys experienced an audio bug when you hear random people talking? it cuts in and out and briefly has a few periods where it stays for a few seconds. was in reserve and kept hearing these 2 talk something about food i knew it wasn’t a voip and i asked them if they were, i was truly confused they said they had not been voiping to me. i explained what i had heard and they were adamant they weren’t speaking over comms. in the end one had said that it happens to him occasionally as well.
