Well the default is to obtain the channels signal. most channels over the world their audio output signal is mono. Rare tvs have the ability to save indivisual channel to their memmoty. Read the tv prospectus!!!

Here is what I found out. I had this same problem. I have cable TV and the signal coming into my house was not very strong. They 'boosted' the signal and this problem stopped. Along the way, they tested that the cable line had been passing through a splitter, so that to the house the signal was good, but by the time it passed all of the splitters, the signal was not strong enough. Now all is well and the problem does not happen anymore.

For some using composite wires instead of the coaxial may not be a possible because you use the red,white,and yellow spaces for your xbox or playstation. Here is another solution if you use digital cable or a similar cable box. This may work for many other cable boxes. Go to your cable box's settings and look for an option to change your "Audio Range". which is probably right now set on either "normal" or "narrow". If this option is on "narrow" then change it to normal and monitor the results. If you continue to recieve this problem then change the setting again to "wide". This should eliminate the box all together. If anything you might only see it once or twice in the entire day instead of ever 20 secs like mine was. I sincerely hope this is helpful.. Let me know.

SOURCE: mono/stereo keeps flashing...

so for us not using cable for this, what do we do? even plugging a game console into this plug will have same results. keeps switching from mono to stereo making the sound stutter. why does the TV get to decide on its own? who thought of that? is there a setting to choose for it so it doesnt have to bother?
