Oh. Then your problem will *NOT* be solved by changing the encoding of
the files, because it is an electrical problem. The headphone socket is
*NOT* compatible with a line-in or line-out socket:

S/PDIF is a digital protocol, carrying digital bits, between two
compatible sockets. No wonder it works.

Um, yes. If it doesn't have a line level output (aka line-out) then,
indeed, it isn't designed for that.

Are you sure you will not burn out the input on your amplifier? That
is, in fact, a genuine risk of what you are doing, although it might
work, more or less...

This will not help. You have an electrical problem, not an encoding
No, seriously, fix it by getting a playback device that is compatible
with your amp, or vice-versa, not by pushing the volume up until you
burn out the amplifier or the iRiver.
