I’m running Spotify version 0.9.4.183-1 and local mp3 files don’t play anymore.
All I get from the logs is “15:58:39.156 I [audio_driver_linux.cpp:18 ] Using PulseAudio”, no proper error message 🙁
After some googling, the fix was simple enough. Install the “ffmpeg-compat” package from the office repo.
sudo pacman -S ffmpeg-compat
Restart spotify and your local mp3 files should now play in your Spotify client.
