Hooking up external speakers to a VIZIO

Use the left and right audio out from the TV

Try a different HDMI port on your TV, or try to use RCA cables.

Without opening set, easiest thing you can do is hook up a small receiver to the audio outputs of tv and then plug your headphones into the headphone output of receiver. And when not using the headphones you can always hook up some external speakers to the receiver - they will always sound better that the speakers that come with the tv.

Hook your TV to a home theatre system. TV.s don't have enough wattage to handle several speakers.

audio output is where you should plug them in.. and the other end into a receiver (stereo system) input.....

First turn the volume all the up on the box, if that does not fix it you need new speakers.

you need a logitech sound adapter or game adapter that costs 4-10$ on ebay.

Connect LR channels using an RCA cable and hook up the speakers on the other end of the game adapter

Yes, you can. There should be a fix or variable output. I would do a variable output, so when you turn up the tv, it will turn up the speaker. If you do a fixed, you have a surround unit.

All the Vizio flat-panels I've seen have ext. line outs to run into home theater/ stereo systems, not all have the external speaker jacks. Either use powered speakers or run through an amplifier. The cable has nothing to do with the audio.

My 32" vizio I bought a week ago does the same things.

Buy an external sound system for the tv. Turn the speakers off in the TV menu. Hook the sound system up to the out speaker hookups on the tv.

You will not only have better found, you will fix the speaker buzz problem.
