Fix ambiguous latency check

Browse Source 
Only compare playback latency, delaylines in tracks do not
push back the capture latency to the source.
The delayline on tracks sits in between disk-writer and disk-reader,
delaying input to align with the disk-reader.

Furthermore tracks may be connected to different inputs,
even though those inputs are usually from the same hardware
device, capture latency of those ports can differ.
