That is really odd. I helped Jochen to implement correct default device selection and also recording capability in SDL2. And I used the SDL2 test programs and they worked ok. Maybe that did not make it into the SDL2 provided by BWW?

From SDL2 I know that it uses DART. But that should work just fine with the USB audio drivers. At least it does here.

Looking at http://hobbesarchive.com/?submit=Search&search=dosbox&stype=any&sort=type_name&dir=%2F Dosbox is using SDL. Likely a newer version would use SDL2.

Lars:
Too bad. I only fixed SDL2. I cannot even find the SDL that we use.
Maybe it's time to build a version of dosbox that uses SDL2.

Hmm, looking, DosBoxes last release was 5 years back, so likely no SDL2 support though I didn't find build instructions.
There are forks such as DosBox-X, https://dosbox-x.com/ which would be nice to have. Even it comes with an intree heavily modified SDL as well as support for SDL2. This one would be nice to have as it is expanded to run most DOS apps including Win9x.
There is also SDL3 now

SDL3 would be a good add-on to our video libraries. What is really sad is the lack of OpenGL support - though I guess it is almost useless without a real accelerated video driver. But alas, an OpenGL comeback on OS/2 would allow porting many applications. I know - we are a little community.

But let me dream  8)

Hi All

I can confirm that the only sdl2 game I have installed plays sound using Lars usb audio driver packages.
I have several sdl games installed but cannot test with them as they all need snap installed to run...


Regards

Pete
