I updated to version 3.6E and noticed some audio issues (via optical output):
There is harsh treble and sibilance, which makes the sound slightly unpleasant and fatiguing to listen to. The tonal balance feels too bright and piercing. Previously, I had tuned the DSP based on version 3.6, and the sound quality was very good. I recommend fine-tuning the system to reduce the harshness and brightness in version 3.6E.
Additionally, I’m unable to adjust the speaker power output. Although I can move the slider, it has no effect (specifically in the “Advanced Sound” settings on the head unit). In the previous 3.6 version, adjusting speaker power levels worked as expected and took effect immediately. (Dudu7 7870 -12.3')
