PULSEAUDIO=on rationale is described in r404687 commit message. HTML5 audio uses libcubeb which supports multiple audio backends but the logic to select one isn't particularly advanced. // simplified from // https://dxr.mozilla.org/mozilla-central/source/media/libcubeb/src/cubeb.c int cubeb_init(cubeb ** context, char const * context_name) { // Ordered list of available backends int (* init[])(cubeb **, char const *) = { pulse_init, alsa_init, oss_init, }; // Use the first successfully initialized backend for (int i = 0; i < NELEMS(init); ++i) { if (init[i](context, context_name) == CUBEB_OK) { return CUBEB_OK; } } return CUBEB_ERROR; } // https://dxr.mozilla.org/mozilla-central/source/media/libcubeb/src/cubeb_pulse.c int pulse_init(cubeb ** context, char const * context_name) { ... libpulse = dlopen("libpulse.so.0", RTLD_LAZY); if (!libpulse) { return CUBEB_ERROR; } ... WRAP(pa_threaded_mainloop_start)(ctx->mainloop); if (pulse_context_init(ctx) != 0) { pulse_destroy(ctx); return CUBEB_ERROR; } ... return CUBEB_OK; > $ LANG=C paplay Track01.mp3 > Failed to open audio file. paplay(1) doesn't support MP3. Try passing --list-file-formats then transcode to one of those e.g., $ ffmpeg -i Track01.mp3 Track01.wav $ paplay Track01.wav or $ ffmpeg -i Track01.mp3 -f wav pipe: 2>/dev/null | paplay >> firefox package built by pkg.freebsd.org doesn't pull pulseaudio. > > What does this mean 'pull pulseaudio'? "pkg install foo" only installs category/foo port dependencies that are necessary to run package. For example, BUILD_DEPENDS won't be installed. > How the PULSEAUDIO option is set in this official pkg? Maybe query pkg.freebsd.org using pkg(8) instead of asking e.g., $ pkg rquery "%n-%v" firefox firefox-46.0_1,1 $ pkg rquery "%Ok=%Ov" firefox | fgrep -i -e alsa -e pulse ALSA=on PULSEAUDIO=on $ pkg rquery "%dn-%dv" firefox | fgrep -i -e alsa -e pulse alsa-plugins-1.1.1 alsa-lib-1.1.1 Also see pkg-search(8). >> If audio/pulseaudio doesn't work *by default* file a bug for the >> maintainer (gnome@) to notice and maybe CC consumers (e.g. gecko@). > > Should I file a bug due to the above error, or do I something wrong? > I have applied the change in /usr/local/etc/pulse/default.pa paplay(1) producing silence with default pulse/default.pa would be a bug. Another example, if pulseaudio daemon opens /dev/dsp0 instead of /dev/dspN where N is the value of hw.snd.default_unit. $ sysctl -a | fgrep unit hw.snd.default_unit: 0 hw.pci.default_vgapci_unit: 0 $ procstat -f $(pgrep pulse) | fgrep dsp 49022 pulseaudio 10 v c -w---n-- 1 0 - /dev/dsp0.0
