It might be helpful if you told us
1. what audio your troublesome recordings have (mp2, aac, ac3??) -
mediainfo reports this pretty well.
2. What your audio hardware is in each case - chipset, path to the
speakers (analogue, spdif, hdmi, through an external amp or direct to
the tv, etc etc.)
3. what ALL your audio settings are.
