Soundbar 6000 making popping noise

jskamm

Have a Soundbar 6000 with wireless subwoofer, connected to a 42 Olevia lcd tv. Use an optical cable between the tv and the
soundbar. Everything worked well for 6 months, but now sometimes when changing the channel the soundbar makes a huge
popping noise then looses audio. Audio will come back on eventually, low audio at first then progressively increases. Does anyone have any idea what I can do to fix this problem.

Sorry if this is the wrong forum for this question.

Hello,
Welcome to Polk's forum, I'm sorry there's a problem. There shouldn't be any extraneous sounds when you change channels. What is your source device? Cable or satellite receiver? Can you try connecting another audio device into the SurroundBar? A DVD player?
This would show if the problem is with the bar or elsewhere.

I am using Comcast Cable as my provider. I have a Sony DVD player with an optical output. I'm assuming you want me to connect the optical output on DVD player to the soundbar? Then turn on the DVD player to test the audio. If this is the case, then how do I test the audio. Since this is an intermittent problem and only happens when changing the channel, how do I test it with my DVD player. I can't change channels on my DVD player.

Sorry, Hate to sound stupid but I'm good with electronics.

Thanks

Hello,
Correct, if the Sony has a digital audio output connect it to the bar using input 1, then begin playing a DVD and then use all of the functions on the player, "pause" "fast forward" etc to see if there's any bad sounds. If the cable box has digital audio outputs you could connect it directly to the bar as a test aw well.

So here's what I did. Connected the optical cable between the digital output on the DVD player to the source one port on the sound bar. Everything Seems to works okay. So far no popping noise. Next, connected the optical cable to the digital output on my Comcast DVR player and source one port on the sound bar. Everything seems to work fine. My LCD tv is working perfectly with no noise from the tv speakers.

So what does this mean? I'm not quite sure. Any ideas from anyone?

Thanks.

Hello,
It is possible the digital connection between the cable box and the TV isn't providing a sufficient ground. Try placing a standard RCA type cable between any unused analog connection on the cable box and with the TV. If the popping sound remains try the RCA cable between the cable box and bar.
This will give a good physical ground between the cable box and TV or speaker.

Okay Ken, I'll give that a try. One question, though. When connecting the RCA cable between an unused analog connection on the
cable box to one on the tv, I'm assuming you want me to reconnect the optical cable into the digital output on the tv and the source one input on the sound bar? Because the popping only occurs when the optical cable is configured this way. I'll try this
configuration and if the noise remains, I'll try your second suggestion. Regarding your second suggestion, my soundbar does not have a port for RCA cables. There's one digital port and what looks like two phone connector type ports. So I'm not sure how I'll connect a RCA cable between the cable box and the soundbar. Any suggestions?
Thanks jskamm

Hello,
You are correct, you'll need a 3.5mm cable to RCA type to make the connection to the bar. The goal is to make a good mechanical ground connection between components. If the TV has an RCA type connection, try connecting the cable box and it first.
Yes, reestablish the digital connections you've already had.

Ken,
Sorry, been away. I'll try your suggestion tonight and let you know how it went.
Thanks
