The browsers will not play sound on certain websites, Namely, bbc.com, bbc.co.uk, https://www.digitalconcerthall.com.and others. Video is perfect. Ideas please.

I'm getting the same with Pale Moon too, so it's probably an issue with UXP.
There is this message in the devtool's console:

Re: No sound on certain websites
When I played any audio or video on https://bbc.com, Basilisk froze and became unresponsive, CPU was at 15% along with 740MB of RAM until I ended the process from system monitor. Same thing on Pale Moon. Audio does work for me on Invidious, tho.
