Ok, looks like these messages only appear in conjunction with a
speakerbox. So...
- when do these messages appear? When playback starts or later?
- do you hear distortions when these messages appear? I mean besides the
short clicking when playback starts ( which I'll hopefully get rid of )
- any distortions at all? Since the mp3 decoder eats a lot of CPU time
you can expect echoes and skips when some other process tries to do
something IO- or CPU-intensive. Anything besides that?
- does anyone get these messages without an onboard codec? Or none of
these messages with a speakerbox?

have fun
Michael
