Background music doesn't play

Hello,

I have detected the following behavior:
If we change the render to Vulkan, load a rom and close it, when we return to EmulationStation the background music does not play.
It does correctly with opengl.

Here is the place to report the behaviors that we are detecting or better add them in the github?

Greetings,

Hello, give me more details, with which cores?

I'm think is with all cores.

But I tried with:
Flycast
Beetle PSX HW
snes9x
mgba
nestopia
gambatte
genesis plus gx
mupen64 plus next (v2.1 with vulkan support)
parellel
fbneo
neocd

For example, if I launch a snes9x rom with the gl core render, when I close the rom and return to emulationstation the background music persists. If I do the same test with the vulkan render, when I return to emulationstation the music doesn't play.

I use mp3 with cbr coding at 128kbs.

Regards,

Thanks for your feedback... very strange, we are several retrobat users to have tested with the parameters that you give us, and we do not meet this problem.

There's absolutely no reason Vulkan ( which is related to video ) corrupts the bg music.
What's in the es_log.txt file, when U come back from a game ? ( see "AudioManager" lines )

Anyway, I don't know what we can do. We don't reproduce it. Maybe it's simply related to your audio drivers. Try upgrade them.

I deleted the log file before I ran the tests. I started emulationstation, with music. When I started a rom and closed it, I came back to ES without music.

I've attached the log.

I'm beginning to suspect that the problem is the platform and drivers used. I am currently on a NUC BOXNUC8I3BEH2 (i3-89109u with intel iris 655) and another NUC NUC7CJYH2 (celeron J4005 with UHD 600). If I launch retroarch directly with vulkan, without going through retrobat.exe, the same thing happens to me, I have no sound in the roms. This does not happen to me with an MSI laptop with NVIDIA 1070 (running the same retrobat installation). I'll continue to investigate, but with the information I have on the table, aim for drivers.

If I find something I will tell you.

Greetings!

Log does not help. It just shows that you launched ES but you leaved immediately without even launching a game.

I just did another test and the log shows something interesting, I attach the interesting lines:

I've tested with WASAPi exclusive mode on and off (with a windows restart on every change), with the same results.

I have also installed the vulkan runtimes, without changes. ( https://vulkan.lunarg.com/sdk/home )

I really don't see how we can help. It really looks like it's a driver problem with WASAPI once it is used by retroarch it's not available anymore to the other apps, it acts just like the wasapi audio device disappeared.
Try another driver... Or avoid Vulkan... Or avoid playing music ;-)

Or maybe try to change retroarch audio driver, see if that changes something.

I tried all the retroarch audio engines, and with the vulkan graphic rendering the only audio engine that works is dsound. With the other audio engines there is no sound.

The use of vulkan is to take advantage of the swap chain at 2 instead of 3 and the hard gpu for free. That is, to reduce latency, especially on cores where run_ahead is not possible. (hardware accelerated cores)

It's not really a serious problem, with glcore or directx12 rendering everything works very well, but with more inputlag. I think it can survive. And I remember, it happens to me with integrated intel graphics, with dedicated graphics cards I haven't experienced it.

We will keep on investigating, if I find the solution I will comment on the forums

Retroarch d3d11 or d3d12 video driver and wasapi or dsound audio driver can work fine on Windows.  
I didn't find emulatorstation's sound card driver configuration in retrobat
Retrobat 3.1 should be the sdl driver used
