I'm reporting a bug which we tracked down in the german rockbox forum.
Rockbox plays a loud distortion (without music) if you have bass and equalizer both turned on. Any bass setting above 0 shows this behavior.
Tested with a current build after reseting the settings. (r23566-091108)

steps to reproduce:
01. download current build
02. reset settings
03. apply bass
(no distortion this far when resuming playback via menu)
04. apply EQ, > distortion when resuming playback after stop
05. turn off bass > no distortion
   test.cfg (0.3 KiB)
This task depends upon

I think this also happened in my Nano 2G, but only once, so i didn't need to report it. Right after the last track in the playlist finished, a very loud white noise freaked me out. It didn't stop, so i just reset it.

What happens if you apply some EQ pre-cut (say, 5 dB or so)? Those EQ settings apply quite a bit of bass...

thanks, I look into the pre-cut setting.
