[Pkg-alsa-devel] Bug#642484: Squeaky sound output when playing rmvb (Real Media Variable Bit) video format files

[雪山飞狐Flying Fox of the Snowy Mountain]

Package: linux-sound-base
Version:  1.0.23+dfsg-4

Symptom:  Squeaky sound output when playing rmvb (Real Media Variable
Bit) video format files.  However when avi, mkv, DVD are played, sound
out put is good. Seems to affect rmvb files only.  Tested with vlc,
Movie Player and KMPlayer: all produced the same symptom.
