Aleksander Korzynski pointed out to me the recent LAME heresy with
respect to Replay Gain: rather than using the 83 dB SPL reference
specified by the Replay Gain proposed standard, LAME uses a reference
of 89 dB as of version 3.95.1.
Combined with the default pre-amp gain of +6 dB implemented in madplay,
this often results in an over-amplified signal and clipping when Replay
Gain is enabled.
I've just released version 0.15.2b of madplay that compensates for this
problem:

Hi everybody,
I am a user of the source based Lunar Linux distro
(www.lunar-linux.org). This distro contains the mad
stuff. In order to use the alsa module (last version
1.0.2c) i use this simple patch. Please incorporate it
in the package.
Regards,
Florin
