[meta-freescale] GstVolume with dizzy is not working when changing to a value inferior to 1

[scerveau]

Dear all,

I'm facing an issue with dizzy on imx6q and gstreamer 1.4.1. The volume 
element is not working properly.
Whith this pipeline:

gst-launch-1.0 audiotestsrc ! volume volume=0.5 ! alsasink

The sound level is equal to 0 instead of half of the standard volume. If 
i put volume=1 this is working properly.
Affter investigation i understood that it is related to this line

gstvolume.c:251 self->current_volume = volume; in volume_update_volume

If i put any log just after this line, the behaviour is coming back to 
normal. If i compile with -00 its also working fine.

CFLAGS += " -O0"

That's my fix for now ;)

Please advise on how to fix this issue because i dont know if its 
related to the compiler (4.9.1) or to gstreamer.

Best regards.

Stéphane.
