I just got a clip and it worked fine for about one week. But now whenever I turned down or up the volume the system turns off or freezes what’s going on and how can I fix it. I’ve tried updating it and holding down the power button for 20 seconds to reboot, but none of this has worked.
I have the same problem - if you find the solution please let me know!
Return it. It’s defective. There’s nothing you can do to fix a hardware problem like this.
Also with the greatest respect and admiration to my esteemed colleague Miikerman , the OP stated he had already updated the firmware and nothing had changed. That’s why I recommended he/she return it as it seems it is most likely a defective unit. 
I have a similar locking up issue although mine happens at random, not just when adjusting the volume. Bad thing is it’s out or warranty but it worked fine for quite a while. It has the latest firmware, reformatted the memory 2x, tried everything, just about ready to throw it away. Any other ideas to try?
