Hello I've noticed that volume control acts differently on the internal speakers vs internal speakers.
Primarily the fact that the built in audio uses some sort of multiband compression or volume dependent - dynamic equalization and other DSP modifications (I'm guessing a slight reverb as well)? The volume control seems to control dynamics at the lower levels and keeps the frequency response relatively balanced for all volume levels for human speech (preventing overall muddiness or overwhelming sibilance) at the expense of dynamics,
Whereas the external output sends the pure signal and the volume control modifies the gain. A lot of youtube and video content is either poorly mastered and consequently suffer from a lot of boominess, and sudden loud noises, and sibilance. Which are pretty bad when using headphones or nice external speakers.
Consequently I was wondering if there were a way to keep the CoreAudio running? Either by spoofing the internal speakers through the headphone jack or software solutions. Thank you
