For www/firefox version 53.0_2,1, sound does not work when built with the standard configuration. I recently installed FreeBSD 11.0-RELEASE-p9 and built all ports from scratch, almost entirely with the default configurations. I found there was no sound in firefox, including YouTube videos. Other applications I tested for sound still worked, including opera, xmms, vlc-qt4 and the chrome browser. After much searching, the suggested solution in various forums is to turn off Pulse Audio in the configuration. This I did. After rebuilding firefox, the sound worked again. For reference, here is the configuration I used, after turning off Pulse Audio. ALSA : on BUNDLED_CAIRO : on CANBERRA : off DBUS : on DEBUG : off DTRACE : on FFMPEG : on GCONF : off GNOMEUI : off INTEGER_SAMPLES: off LIBPROXY : off OPTIMIZED_CFLAGS: on PGO : off PROFILE : off PULSEAUDIO : off RUST : on SNDIO : off TEST : off
We have firefox 57.0.4 and 11.0 has EOL. Overcome by events.
Probably caused by broken PulseAudio configuration e.g., not refreshed after bug 211684 landed.
