Seems to be same bug as closed one #529098 When installing media-sound/apulse-0.1.13 with USE=sdk, libs are put in /usr/lib64, and not in /usr/lib/64/apulse, and firefox links them in /usr/lib64/firefox from ../apulse for lib in ../apulse/libpulse{.so{,.0},-simple.so{,.0}} ; do # A quickpkg rolled by hand will grab symlinks as part of the package, # so we need to avoid creating them if they already exist. if [[ ! -L ${lib##*/} ]] ; then ln -s "${lib}" ${lib##*/} || die fi done So no sound in firefox. I manually created /usr/lib64/apulse containing : lrwxrwxrwx 1 root root 21 19 déc. 10:47 libpulse-simple.so -> ../libpulse-simple.so lrwxrwxrwx 1 root root 23 19 déc. 10:47 libpulse-simple.so.0 -> ../libpulse-simple.so.0 lrwxrwxrwx 1 root root 14 19 déc. 10:47 libpulse.so -> ../libpulse.so lrwxrwxrwx 1 root root 16 19 déc. 10:47 libpulse.so.0 -> ../libpulse.so.0 to not have to create links at each firefox update.
In sdk mode apulse tries to be a drop-in replacement for pulseaudio: it installs libraries and headers the same way as pulseaudio does. Of course in this mode apulse is still NOT a full pulseaudio replacement as it lacks full pulseaudio functionality. Also please note that apulse[sdk] is Gentoo enhancement and it was *rejected* by upstream: https://github.com/i-rinat/apulse/pull/93 So, if you are using apulse[sdk], just use it as you would use pulseaudio in yor package. If you need a stock upstream apulse, install it without sdk and provide necessary headers yourself (e.g. install pulseaudio) or use pre-build firefox-bin.
