Hi Dom,
your mods are working fine, the problem is on the firmware side. More in detail, now we're using a filtered PWM signal to generate the demodulated audio, but the analog path from the PWM filter to the speaker introduces a good amount of attenuation. There is an alternative path which uses the HR_C5000 but I didn't worked on it yet because of lack of free time. In any case I hope to work on it soon.
You can also try this mod travisgoodspeed/md380tools#98
