Whether you can hear that also depends on your cans. I can't hear it
with my PX-100 (open cans). However, it is very noticable with IEM's.

The noise comes from the LCD being on and IIRC buffering.

No, The original firmware have this annoying habit of hiding and
rehiding the "Music" directory. You can either unhide the directory
(which you can't do under Linux) and rename it or create a new directory
and move your music there. I personally use "Musica".

There are patched versions that does that. You can try one of my builds
(new version in about half an hour):

This only happens with the 1.1 version of the hardware. There is a
temporary work around in my builds.

IIRC, there is talk of a plugin reorganization.

It doesn't have to be mounted when installing the bootloader (it uses
raw parition access). However, it takes a few seconds for the USB
subsystem to recognize it.
