When I watch Netflix on my TV and try to have sound through my receiver I get background music etc fine but dialogue is quiet and sounds like it's coming through a harmonica microphone. Surround logo lights up on the amp and everything but just weirdness comes out. Because of the way my house is setup I can't connect the TV to the amp through anything other than HDMI so ARC is the only option if I want surround sound out of it.

Any tips or tricks to sort it out would be appreciated. Have messed around with settings in the receiver and TV with no luck.

5.1 through Polk 265-RT FL/FR, 255c-RT centre, 90-RT RL/RR, and a PSW10 sub (not that the speakers matter at all)

Does the sound sound correct if you just play in stereo mode?

Can you turn off surround features in audio output of TV. My Sony a1 has all sorts of sound output options including a dialogue amplify sort of thing.

?factory reset and try to output in stereo from TV and amp
.
Might help check for codex incompatibility between sound output of TV and amp input. IE the TV might be modifying it's audio output which confuses the amp.

I agree with afe66; have a read from your tv's user guide re what sound outputs do what. I'm not in front of my TV but I'm sure its outputting as PCM as its the best option for me. I googled the and found the following words I hope this may help.

'...

Bitstream sends the signal out relying on the connected equipment to understand the format.
So outputting Bitstream of Dolby True HD you would need an amp that can handle that.

If you output PCM the sound is already decoded so the receiving equipment does not need to support the original codec.

So IMHO if you have a current amp that supports all the HD sound formats then Bitstream is the way to go.

Turns out the speakers do matter. One of the mid/woofers in the centre channel has blown
