Subject: [PATCH] Remove some of DShow-dependent in AudioCaps.

This code was used to loop over all the audio devices and print their
names to a log file. No other initialization or parameter setting was
done. I'm quite sure the world will continue to operate without device
names printed out to an encrypted log file. ;)
