appletv sound problems, somewhat detailed

[guitarist]

By going to Radio Shack, you paid an extra $40 for convenience and instant gratification. If you'd had the time and patience, you could have purchased a good quality HDMI cable for 1/5 that price. But you got the problem solved immediately, which must be a relief. Next time you need an HDMI cable, you will hopefully have the time to price compare and order one online. But for now, think of it as a convenience tax, and don't worry about it.
