Default Audio issues since Kit Kat

Since I've upgraded to Kit Kat I keep losing audio through Bluetooth & HDMI. Normally turning off Bluetooth then back on or rebooting the phone fixes this but there are other times that it just hangs with no audio at all. Anyone else experiencing this?

I've gone through my frozen apps to make sure there is no audio app that could cause this that has been frozen. I have even gone as far as defrosting most apps then refreezing them one by one to see if any one in particular causes the issue. No luck thus far so if anyone has any advice please let me know.

Thanks for your help!
