As far as Zekr source code is concerned, I can bear witness that there
is not a single line of anything related to sound or alsa. We just use
basicplayer playback API: open(), play(), pause(), stop() and
setGain(float), which itself delegates to standard javax.media (JMF)
methods (for the case of mp3, it then finds mp3spi, which uses tritonus
and jlayer API).

question: does this problem also happens with .ogg, .mp3 and .spx files.
I want to know if this relates to jlayer API, or other libraries.
