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. > [ao/alsa] Playback open error: Device or resource busy > connect(2) call to /dev/shm/jack-0/default/jack_0 failed (err=No such > file or directory) > attempt to connect to server failed > [ao/jack] cannot open server > ALSA lib > /var/tmp/portage/media-libs/alsa-lib-1.0.29/work/alsa-lib-1.0.29/src/pcm/pcm_dmix.c:1024:(snd_pcm_dmix_open) > unable to open slave > Could not open/initialize audio device -> no sound. > Audio: no audio > : 00:00:00 / 00:05:56 (0%) > > I reinstalled alsa-lib and mpv but the problem remains: > Why does alsa tries to load a library which is meant to be found under > /var/tmp/portage? > > Best regards, > Meino > > > > >
