My community has a FIOS CHS335HDC with a P265v3, both have been used for less than 1 hour so far. The issue that I'm running into is that the cable box does not control the volume i.e volume set to 0 in STB mutes the sound, volume between 1 and 30 is at the same level (it does not increase or decrease). Remote control is working fine and it's set to control the volume through the STB. STB is set for variable volume in the audio settings.
