How can you expect anyone to help you if you don't at least provide the model number(?) What other AV sources are involved? Help us help you
During the F1 this weekend I noticed that the audio had somehow switched and began playing in a reverb kind of mode, this I cannot remove apart from switching audio settings to HDMI in the reciever which is apparently for TV audio only.
It sounds like any channel or disc is being played in a cathedral, any ideas?
