Sam Lantinga 302a6e62aa Fixed bug 3484 - DSP driver does not detect /dev/dsp0 
Tobias Kortkamp

using SDL 2.0.5 (and a repository checkout) on FreeBSD 11.0 I get this output
from testaudioinfo with SDL_AUDIODRIVER=dsp:

INFO: Found 8 output devices:
INFO:   0: /dev/dsp
INFO:   1: /dev/dsp1
INFO:   2: /dev/dsp2
INFO:   3: /dev/dsp3

INFO:
INFO: Found 3 capture devices:
INFO:   0: /dev/dsp
INFO:   1: /dev/dsp4
INFO:   2: /dev/dsp5
INFO:

This is /dev/sndstat:

Installed devices:
pcm0: <NVIDIA (0x0040) (HDMI/DP 8ch)> (play)
pcm1: <NVIDIA (0x0040) (HDMI/DP 8ch)> (play)
pcm2: <NVIDIA (0x0040) (HDMI/DP 8ch)> (play)
pcm3: <NVIDIA (0x0040) (HDMI/DP 8ch)> (play)
pcm4: <Realtek ALC887 (Rear Analog 7.1/2.0)> (play/rec)
pcm5: <Realtek ALC887 (Front Analog)> (play/rec) default
pcm6: <Realtek ALC887 (Rear Digital)> (play)
pcm7: <Realtek ALC887 (Onboard Digital)> (play)
No devices installed from userspace.

I'd expect to find /dev/dsp0 in the output device list.  It's not detected
because of a a small logic error in SDL_audiodev.c (see attached patch).

With the patch applied I get this which is what I'd expect:

INFO: Found 9 output devices:

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
with README.md

Enjoy!
