Looking for better firmware

[Rich62]

HI,

I'm looking for a *better* firmware for my mp4 player - the one installed is producing noise while playing music: whenever the animated image showing some bars changes it's shape I hear some high frequency noise. Even though the noise is not loud it still is very annoying - even when the display gets dark I can hear it.
I think that if the image does not change I might have a chance to get rid of that noise.
My player uses a ACTON Chip ATJ2091N, the display is a 2" screen.

ic version = 0x000B
storage info = 0x0602, 0x0000, 0x0000, 0x0000
device = 'S1 Mp3 Player'
manufacturer = 'Wilson Co. Ltd.'
bootflash type = 'F285'
brom version = 3.0.80
firmware version = 9.1.52

The unit looks like that:


Thanks a lot!
Regards
R.
