17867,Sound Blaster 16 Synth not working?,MarchHare,,"I've been trying to figure this out for some time. Apparently some SB16 sound works, but other SB16 doesn't. Specifically, the synth does not seem to be implemented. I will use DOS programs as a good example, as I tend to know what they should sound like. For instance, Doom is able to run, and I can hear sound effects, but not the music.

So I'm attaching some basic code. This code was originally written in basic, but given the nature of what it did, I was able to convert it to a c function that was compiled and run with a bootloader stub. I tested this on a boot disk in a real machine, and it worked. (The sound way a kind of growl-ly purr that rose, then got quieter, sounds kind of like a vroom, but with a square wave). So this code is OS independent, you just have to call it from a bootloader stub and it should work.

When I use it on Virtualbox, it doesn't make any sound, nor does the basic version of it. In fact, the basic version also checks for a sound blaster and can't find one on Virtualbox. So I'm not sure what's going on, but I suspect the synth portion still needs to be implemented?

If someone could point me at some code that does something similar for Intel HDA, I'd love to see it, because I wouldn't mind learning how to program for that one instead.",enhancement,closed,audio,VirtualBox 5.2.10,wontfix,sound blaster,,all,Linux
