WMA2 mono radio stream leads to crashes

mms://170.155.145.40/AM_Provincia

This is reproducible on Windows (DirectSound) and OS X/iOS (AudioUnit, AudioQueue), but surprisingly not with PulseAudio (adummy is ok, too). Due to bad timing, we resample this source a lot, the resampler complains "Cannot resample: Input and output data arrays overlap."

It terminates here:

This is a regression from 2.1.
