"About" in the browser says this is Tor 9.0.9, up to date,Firefox 68.7.0esr) (32-bit) up to date.
While in Windows 7 Ultimate (32 bit), sound & video work fine locally & on web in both Firefox and TOR. In Knoppix, both work locally & in Firefox. But in Knoppix in TOR, I can play video but THERE's NO SOUND.
I'm illiterate in unix/debian commands. This is all new to me. Can someone guide me in plainspeak through trying some fixes in Knoppix?
I'm coming up empty on the internet. I would very much appreciate any help. Thank you - AntiDiluv

The only application I am currently aware of that is unable to produce sound (after manually starting Pulseaudio) is Tor Browser 9.0.5.
To test whether this is an issue of the Firefox release Tor Browser is based on, namely 68.5.0esr (64-bit), I downloaded that and was able to play audio successfully (e.g. on Youtube).
I had a look at the Tor Logs, but they seem to only log events related to Tor connectivity, not browser-related events.

i would need to re-compile firefox with
--enable-alsa
--disable-pulseaudio
in the mozconfig
for native alsa support
or with
--enable-jack
--disable-pulseaudio
for native jackaudio support
why i prefer alsa over pulseaudio?
cos alsa gives lower latency
and better audio video sync
pulseaudio is just too big for me
--
workaround: apulse
if you dont want to re-compile firefox
or if firefox completely drops alsa support
then use apulse
from https://github.com/i-rinat/apulse
as pulseaudio emulator on alsa
its a partial implementation of the pulseaudio API
which runs faster than the whole PA server
apulse needs dmix
see
/usr/share/apulse/asoundrc.sample
and edit your
/etc/asound.conf
--
to make torbrowser play audio to alsa
in your
~/.local/share/torbrowser/tbb/*/tor-browser*/Browser/firefox
replace
exec "$basedir/firefox.real" "$@"
with
exec apulse "$basedir/firefox.real" "$@"
