I have my Samsung Harman Kardon 7.1.4 HW-Q90R soundbar connected to my epson 3010e overhead projector. The connection is made via bluetooth through my Amazon firestick, which I have plugged into my Epson projector in the HDMI 1. Everything is connected and working, however, I cannot get rid of the sound lag on the sound system. I've tried moving the sound delay to 0, and this only makes it slightly better. My Projector is about 6 years old (so not too bad I hope). It has outputs for HDMI 1 and 2 (neither labeled arc), USB, and RCA cables. There is no optical input/output on the projector so not an option.
Does anyone know how I can correct this? Is BT slower than if I try to hardline? Is there a more optimal way for me to configure and reduce the lag?
I'm sorry to hear that, what is the current firmware version on the sound bar? Also does this occur when you use HDMI?
You can see the current firmware version by using the smarthings app and gettting the sound bar connect to the app.
