Bug 256045: www/firefox: Selecting audio capture device doesn't do anything
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256045



--- Description ---
I've tried this using both the OSS and pulseaudio backends.

When I use a site such as Discord, Firefox will show a list of /dev/dsp*
devices to choose the input from. However, selecting a non-default device
doesn't actually change anything.

I have a mic that maps to /dev/dsp2 (the default), and a webcam that maps to
/dev/dsp6. When I switch from 2 to 6, the browser still takes input from 2. 

If, in pulseaudio, I set the default to dsp6, changing the input from 6 to 2 in
the browser does nothing. All input still comes from dsp6.

It used to work. I had to go into the settings and change the input device
every time, as I prefer the webcam mic. Not sure when it changed, sorry.

Running FreeBSD 13.0-RELEASE on amd64.
