[gst-devel] Problem with equalizer-10bands

[Yogesh Marwaha]

Hello,

Here are the verions (all are up-to-date for openSUSE 11.1): -
gstreamer 0.10.22-42.pm.1
gstreamer-base 0.10.22-42.pm.1
gstreamer-good 0.10.14-42.pm.1
gstreamer-ffmpeg 0.10.7-42.pm.1

I've installed banshee and problem exists there also.

Regards,
