Ugh. I had the exact same issue with Qt and it took me forever to track it down[0].
Even though it's been fixed since 2017 I can confirm that there's still lots of network-using software out there that isn't using the most recent Qt library. Installing any of it will destroy your ability to have lag-free video chats or do any other real-time streaming.
I've always been in the "wires wherever possible" camp and it's things like this that are keeping me there. Hopefully headphone jacks don't go totally extinct anytime soon...
