pymumble_py3.errors.CodecNotSupportedError: 

i ended up posting a issue on main mumble repo by accident and someone did say I can only tell you that we have removed support for the CELT codec in 1.5 as virtually every client in existence should be using Opus by now.

Into you debug mesage you can see:

message: CodecVersion [...] opus: false

That is what the server is sending. Since pymumble only support opus, when the server try to send a no opus sound, you will get this error. Do you have a recent server ? And more important, you maybe have a client (maybe a old one) making the server fallback to CELT.

On the GUI, you can right click on people to see the one making this issue.
