Fire stick has got only one HDMI port, which will be connected direct to the TV. Then I will have a problem in connecting my existing 5.1 channel Home theater, which does not have Bluetooth compatibility. (please note I am looking for an Android Box just because my Jio STB does not have an Audio out port and as such I was not able to connect the 5.1 channel).
When I checked about this with other sources, they advised me to do the connection as under:
Fire stick to HT by HDMI cable, and then HT to TV by HDMI cable. In this case, I need two HDMI ports in the HT, but my HT has only one HDMI (ARC out) port and one Optical port. (TV does not have any ARC or eARC ports but has optical port).
Mi Box comes with an Audio out port from which I can connect to my HT optical port using a Toslink to mini-toslink cable and then HT to TV via HDMI cable.
