Remove duplicate surround entries. Fix for #27

[GitHub pull_request - opened]

alsa-project/alsa-lib pull request #30 was opened from DarkWav:

Try to remove duplicate surround entries to fix crashes with certain apps by changing the config a bit.
This would have multiple benefits.
1. It allows all the bonus devices (such as samplerate) gained from Version 1.2.2 to stay.
2. It still keeps surround devices around, just removes duplicate entries if they exist.
3. It fixes Issue #27 and all Unity3D-based games.
I'm not sure about side effects tho, but they seem to be reasonably low from what I've tested.
Thanks for taking a look.
