In https://bugs.debian.org/1089246 there are some patches which upgrade
mumble to a newer version, which is also available here:
https://salsa.debian.org/diederik/mumble/-/tree/update-to-1.5.735

There is an unstream commit included in v1.5.613 (and newer):
b5a67c05fb54 ("REFAC: Fix tons of warnings and non-portable code")

That commit adds ``static_cast< std::uint8_t >`` to various statementsin
PipeWire.cpp, among many other things, so that could be relevant here.

So, could you try if the problem is still there with a newer version?
