Unlikely, if weak WiFi it's not impossible, and remember it's a friend of yours, which you don't live with
I say that because usually when you ask lots of questions and try and fault find what someone says , it's not always what they originally said, which misleads what the real problem with audio might be, weak WiFi can cause audio loss, and even a device elsewhere could potentially interfere with audio when WiFi weak, possibly it's a coincidence
