After a long wait and much anticipation Amino support got back to us regarding 10 and 13 cutting out.
Turns out it is not compatible with having AC3 turned on. Disabling AC3 in Hardware Settings seems to have cleared up the issue. At least for the 10 minutes that I watched with a customer over the phone. Usually the audio cut outs happened every minute or even every few seconds.
This can be done via VNC for the customers so please do it for them. Let them know you will remote in to the STB and update the settings for them. Then have them watch and let us know if there are any further issues.
So to fix it:
1) VNC into the STB (How to log into Entone STBs via VNC)
2) Go to Menu\Settings\Hardware Settings
3) Enter 1234 for the password (in almost all cases unless it is set differently in Minerva)
4) Scroll down to AC3 and set it to disabled.
5) Submit the changes.
Now the changes are applied.
