No Volume control with MyTV online and Terrarium

While running Terrarium with some files I have no volume control no matter what I set the control to. It will stay the same volume till it goes all the way down to mute. Tried installing the new audio codec file from addon linker but that didn't seem to help.

I'm running MX player 1.9.17 (ARMv7 NEON)

I also noticed that some channels on MyTV Online have no volume control as well. No matter what I set the slide to up or down I get the same volume till it goes all the way down then it mutes.

It is HDMI. The sounds works on alot of the channels and alot of the videos but some I have to use the volume control on the tv.

Update.... I did a factory reset on the box and it seem to take care of the problem I just went through 30+ channels and all of them I could control the volume.
