I have ;-)

If you could try something on your system, I'd appreciate it.
Try adding
NetworkThreading=0
to your ~/.RealNetworks_RealMediaSDK_60 file

This will turn off threaded networking, which is a semi-experimental
feature at present.

I believe that the audio device implementation for some machines may use a
braindead resampler (sample repetition) which I believe could cause the
sort of aliasing you experience.  Most audio apps for linux open the
device at 44100, resulting in no aliasing.  RealPlayer chooses the audio
dev. speed based on datatype.

One way to work around this is to use ESD, which AFAIK always opens the
device at 44100.  Another is to look into whether the audio device
implementation has a quality (fft) resampler.

I'm sorry to hear that.  If you want it to work well straight away, please
try turning off threading and using ESD.

Thanks,
