After recent upgrade I have no sound. Running as root: alsamixer XDG_RUNTIME_DIR (/run/user/1000) is not owned by us (uid 0), but by uid 1000! (This could e.g. happen if you try to connect to a non-root PulseAudio as a root user, over the native protocol. Don't do that.)
Does dir: /run/user/1000 should be own by "root:root" or user on the system? When I run: chown root:root /run/user/1000 alsamixer ALSA lib /var/tmp/portage/media-plugins/alsa-plugins-1.2.7.1-r1/work/alsa-plugins-1.2.7.1/pulse/pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Access denied cannot open mixer: Connection refused -- Thelma
