Your process is more or less correct but if you need the sound for low end audio equipment you need compress the dynamic range (less quality but more volume after normalize).
Then:
- You don' need remove DialNorm, NicAudio don't apply DialNorm.
- Open with BeHappy-NicAc3Source(DRC), Configure at (...)
Then the high volume are attenuated and low volume amplified (Dynamic Range Compresion)
- Downmix
- Normalize at end (must be the last DSP function).
Now are max amplified without overflow
