That's just debug output. In order to make dev's live easier alsa-lib uses __FILE__ and __LINE__ macros to point to the exact place where the debug output happened. As portage compiles in /var/tmp/portage/... the debug output mentions that file (note the ".c" suffix - not .so so it's not a library ;)) |

To fix your actual problem (no audio) we need to know how you configured audio (pure alsa/pulseaudio/...) and which USE-Flags you have enabled for mpv and ffmpeg. |
