Hi, STB HDMI output to AV receiver HDMI input, DVD player HDMI
output to AV receiver HDMI input, receiver HDMI output to TV HDMI
input. Connected like this? All devices has to go through AV
receiver, in another word AV receiver is a hub for all the
devices(audio and video). You turn off(disable) the TV speakers and
you control the volume with AV receiver volume control. Is this the
case?

Yes

The OP's problem could be related to an unstable HDMI handshake either
between the FIOS box and the AV Receiver or between the AV Receiver and
the TV. Although HDMI handshake problems usually present as the blank
blue or purple screen, HDMI also provides audio signal and I can imagine
an unstable handshake possibly affecting the audio (although it doesn't
account for the change in TV channel observed by the OP).

I had all sorts of video and audio problems when I used my AV receiver
with the traditional hook-up (as described below) in conjunction with a
FIOS STB. That was also the hook-up recommended in the manual for my AV
Receiver. By simple experimentation, I found a different hook-up that
provides no problems with either.

My hook-up: HDMI output of FIOS STB directly to an HDMI input on the
TV. Optical audio output from TV directly to optical audio input of AV
Receiver. Other connected devices with HDMI outputs (Roku, DVD, and
free-standing DVR) likewise connected directly to TV's other HDMI
inputs. Input selected with TV's input selector, not AV Receiver's
input selector - which remains on "TV". Configure settings of AV
Receiver to activate the specific optical audio input being fed from the
TV. The OP may want to try this hook-up and see if it works better with
his equipment.
