I was wondering if Rockbox allowed playback in mono in the settings?
I was using my iPod earlier today and noticed I can't switch to mono in the settings, it's always on surround. The only solution I (apparently) have is to have a copy of every song twice, one flattened and one layered, or maybe Rockbox.
If Rockbox has this setting I'm probably going to install it on my iPod, thanks for the help!
