Hello, I have FF 52.9.0esr running on Win 98SE, but there is no sound. When I had a CMI8738 based card with WDM drivers installed, sound worked in FF. When I changed it to VxD, it stopped working. Also when I changed card to Audigy 2 ZS with VxD drivers sound refused to work. I've tried clearing cache, reinstalling flash and even reinstalling whole browser, but it didn't help. Have you some ideas where can be problem? Is it something with VxD drivers?
I also changed graphics card from GF 2 MX400 to GF FX 5500 (using the same driver version - Forceware 77.72), and video stopped working. Interestingly, video works on MyPal 28.0, but it has some graphical glitches and is less stable than Firefox on my PC.
