Created attachment 169553 [details]
This patch reads the sysctl and correctly translates /dev/dspX to /dev/dsp.

If the hw.snd.default_unit is set to anything except zero, /dev/dsp0 is not available to programs using portaudio, since it assumes that /dev/dsp and /dev/dsp0 are the same device.

This "fix" actually breaks portaudio that was previously working on my system.

I'm running 10.3-STABLE r306333 amd64, built 9/2/2016.

On my system, sysctl hw.snd.default_unit=2

With ports/audio/portaudio AFTER this fix, I don't get any audio, and cannot figure out how to get any audio (while other non-portaudio apps properly produce sound).

When I do 'cd ports/audio/portaudio ; svn update -r 419597 ; make reinstall' I am then able to get proper audio when running a portaudio application that uses the default configured system sound interface (in my case, hw.snd.default_unit=2). For the purposes of testing, I used one of the portaudio test application, patest_sine8.

I'm not sure if I should file a new bug, or try to reopen this PR.
