XPR 4550 Volume turning off

I have a bit of an odd problem. We recently updated our XPR 4550s from R01.09.00 to R01.12.15 (codeplug 11.00.10 -> 13.02.01). Now we have complaints that every few hours, about 5 or 6, the volume on the unit will just disappear. The display will light up with a call but nothing can be heard. The radios are on a single analog channel with no scan. The only solution is to power off the unit and back on, then it returns to normal. Has anyone seen this before?

Have you tried updating the radios to the latest firmware? R01.12.17.
