Possible fix for bug 5010 - SDL_Init with SDL_INIT_JOYSTICK hangs for…

… 10 seconds when playing audio from another application

Jake Breen

When I run SDL_INIT with SDL_INIT_JOYSTICK it stalls for about 10 seconds (last report was 10,615ms), but only if I'm currently playing audio. (Like in Spotify for example.)

querying something related to device access (last dll loaded)
'BabbysFirst64.exe' (Win32): Loaded 'C:\Windows\SysWOW64\deviceaccess.dll'.

I use a USB DAC because my mobo's audio out is pretty not great. And I've noticed unplugging it seems to solve the issue. I haven't noticed any other issues that are caused by my DAC.

My DAC is the Sound BlasterX G1 https://us.creative.com/p/gaming-headsets/sound-blasterx-g1
Vid = 041E
PID = 3249

My system specs:
- Windows 10 Pro
- Ryzen 2700x
- 16GB Ram
- Nvidia 2070 RTX

Additional USB devices plugged in:
- Valve Index
- Xbox One Elite Controller
