Video but no sound in TOR, Knoppix OS
I'm running an unaltered Knoppix OS from a USB, on a Dell Latitude E6500 laptop: 2 core, Intel 45 chipset, 64bit capable but only running 32 bit; 512 & 8 GB memory capable but 2 GB memory installed. "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.
