source-output: do volume_factor_source application before resampling

Browse source 
Applying the volume after resampling means mismatch between the volume
channel map and the data channel map.

volume_factor_source is not currently used anywhere, so this bug
hasn't been causing any problems. I noticed it while reading the code.
