the subwoofer i got with my vizio soundbar cuts in and out, and its really pissing me off. is there some way to fix this?
its a vizio vsb211

hmm wired ? test connections, clean wire ends

his happens in my surround sound and i have no idea why.

i am assuming its wireless maybe you have your computer and other devices that might be clogging up the wifi .

just an idea

You either has a bad connection, the wire's are not fully inserted, maybe a break in your auxiliary used to hook it up (RCAs), maybe the speakers are blown. There are a many number of things that could be the issue.

What kind of connection does the sub have to the soundbar...RCA?

If so, unplug the RCA cable from the soundbar end (leave it plugged in on the sub end), and tap the end of the RCA cable with your finger. Does the speaker "pop" when you do this?
