FreeBSd-12.1p10
Firefox-82.0.1.
I have a system that has only basic VGA video on board and requires a separate
video card for anything else. The card installed is an Nvidia. I had to
switch the card from interrupt to polling in order to get a stable video player
in Firefox. But now Firefox provides no audio.
On the same system both MPlayer and Chromium handle audio and video without
problem. But these also worked before I switched from interrupt to polling.
The sysctl settings are:
sysctl -a | grep snd

device snd_csa
device snd_emu10kx
device snd_es137x

Can anyone shed some light as to why Firefox, and apparently only Firefox, has
such difficulties with the Nvida setup? And provide some guidance on how to
deal with them.
