Bug 238096: www/firefox: some videos don't have sound - include sndio in
default audio options
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238096



--- Description ---
e.g. https://www.invidio.us/watch?v=_oWcfUt9QUs (a silent gnn is a rare thing)

the same video can be played directly via multimedia/mpv and it seems that
firefox chooses incorrect codecs.

while this may be specific to my computer setup, I have found that switching
the
backend to sndio resolves this issue, on 3 different systems (intel i915, USB
audio devices, HDMI output).

Is it possible to add SNDIO to the default OPTIONS_MULTI_AUDIO? the overall
difference in size to www/firefox is negligable - a few KiB only, and it saves
having to rebuild a very very large port each update.

Alternatively, I can provide more debugging info if needed, I'm just not sure
where to look for that.
