Re: Cheap Surround sound buffer/level shifter

Well the low level hum buzz is fixed but I just noticed that the surround channels were quiet...
Hard to trouble shoot with multiple moving parts in the path that could cause the issues.
I wired up an old stand alone stereo amp to some separate speakers and tried substitution.
#1 I discovered that there was no surround data coming from the optical feed from the TV monitor. The optical feed from the direct TV receiver has the surround info. This was working before so the roku enabled TV (cheap walmart house brand got stupid). It is getting HDMI feed from direct TV and auto detect only reads stereo not dolby surround. It was working just a couple weeks ago.
#2 even with the optical input changed the rear channels are still quiet so I need to debug wiring from decoder, through bump box, to hypex amps...
This is turning into a high maintenance girlfriend....
