I've noticed an audible difference between the quality of the audio output passed through the 3.5mm jack on the Dell XPS 15 9550 versus the 3.5mm jack on the back of the TB16 dock.
The audio passed through the TB16 sounds flat with minimal bass, whereas the audio played direct from the onboard 3.5mm jack sounds bright and rich.
Upon further research it appears that none of the MaxxAudio adjustments are being applied when the laptop is connected to the dock.
I've already ensured all of the drivers are up to date, including going to the relevant component manufacturer.
Is there a way to rectify this and have the USB audio from the TB16 dock sounds as good as the audio from the onboard jack?
Equipment:- Dell XPS 15 9550, TB16 Dock, external 2.1 speakers (via 3.5mm jack)
