Error initializing mumble link: librt

I got this error:

[Info   :   BepInEx] Loading [Mumble Positional Audio 3.0.4]
[Info   : Unity Log] Unix Mumble Link Loaded
[Info   : Unity Log] error initializing mumble link: librt

I think is a glibc issue, because my friend have onother version of glibc (2.33-5)

My system: Arch Linux

kernel: 5.15.24-2-lts

glibc: 2.35-2
