Hello All,

I am new to this forum and I was hoping I can get some help on this annoying problem that I have.
First let me explain what device I have. This a car head unit that runs on Android 2.3.4. (The head unit I have is called AVIN, see www.avinusa.com)
Anyways, every now and then I get this problem where the volume stays at a constant level and cannot be changed. When I try to adjust it, I can see the bar going up and down, as I increase it and decrease it, respectively, but the volume does not respond to the change.

I don't think I will receive that much help as this is a new hardware that no one has probably heard off, but I figure that I ask.
I will mention that a hard factory reset solves this problem, but then I have to reinstall all apps and change all my settings, which I do not want to do every time.
This device is NOT ROOTED.

Thank you in advance,

Andrew
