Dear all,

Here is a patch which fixes the use of gstvolume in 
gstreamer1.0-plugins-base-1.4.1.
The patch has been submitted to gstreamer1.0 master branch

https://bugzilla.gnome.org/show_bug.cgi?id=745667
http://cgit.freedesktop.org/gstreamer/gst-plugins-base/commit/?id=40f4daffd12b84dceb23942a992815e11b5a0839

Best regards.

Stéphane

Yes; this should be done in OE-Core so it fixes the problem in the
base. We shouldn't handle this in the BSP.

The volume element in gstreamer1.0-plugins-base was not working
properly on arm platform if the volume is less 1.0.
