I have several audio problems which might be related to yours:
- Static noise (3.5mm AUX)
Static noise when connecting the FP3 to external amplifiers via 3.5mm (e.g. Car stereo, home cinema system). The signal/noise ratio gets better with higher volumes, but is still completely unacceptable for enjoying music. The static noise does NOT ocur when connecting headphones - Sporadic jumps in loudness (speaker)
When playing low volume music through the speakers, the loudness sporadically jumps up and down.
Has anyone come across a fix to these problems? I fear it might be a hardware problem with the DAC :-/
And finally a wish:
It would be AWESOME if the FP3 Android ROM would offer more than 15 steps to set the media-volume. When connecting my bluetooth speakers I can not set a comfortable volume, as setting the volume to 3 is too quite and setting 4 is way too loud. I know that by rooting you can change the volume steps, but I do not want to root my phone.
My problems have also been reported on Reddit:
