PCM reading in external renderer tries to assign sample rate from WAVE file

Basic info

Bug description

Seems that when reading PCM file into external renderer, the current implementation tries to do this

args.sampleRate = inFileSampleRate;

which is incorrect as there is no sample rate from the file and the argument should be used. This is fixed simply by removing it.

Ways to reproduce

Just try to read PCM.
