pipewire-media-session segfaults while enumerating alsa profiles
Hi!
I tried using pipewire as my main audio server with pipewire-media-session. I've used commit cf2c32f0 and built it with debug symbols included. Unfortunately pipewire-media-session segfaults when the alsa-acp module is enabled. Here is the relevant information from gdb:
