Tomasz,
I'm on:
FreeBSD c720-r368166 13.0-CURRENT FreeBSD 13.0-CURRENT #23 r368166M: Thu Dec 17 13:12:37 CET 2020 guru at c720-r368166:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64
and FF works with 'pulseaudio --start'. I do not say 'works fine'
because I have to restart pulseaudio and FF after plug-in an USB headset
to get it recognized as /dev/dsp2. After plugin I have:
$ cat /dev/sndstat
Installed devices:
pcm0: <Intel Haswell (HDMI/DP 8ch)> (play)
pcm1: <Realtek ALC283 (Analog 2.0+HP/2.0)> (play/rec)
pcm2: <USB audio> (play/rec) default
No devices installed from userspace.
$ ls -C1 /dev/dsp*
/dev/dsp0.1
/dev/dsp1.0
/dev/dsp1.1
/dev/dsp1.2
/dev/dsp1.3
/dev/dsp1.4
/dev/dsp2.0 <**** USB headset
Do you know if the above problem (restart of ....) could be solved?
Do you have any special 'about:config' for FF with pulseaudio?
I found this echo test page https://janus.conf.meetecho.com/echotest.html
extremely useful when trying to solve sound (and video) problems in FF.
HIH
