vihurricane Posted July 16, 2023 Share Posted July 16, 2023 (edited) For the last 2 years, I’ve been dealing with an intermittent issue on my Klipsch Cinema 800 sound bar. It is connected to a Sony Bravia XBR65A8H via HDMI eARC. I also have a pair of Surround 3 speakers. The soundbar powers on and off with the Bravia. Every so often, the speakers will emit a low squealing noise when they turn on with the tv. The display comes up and I am able to change the volume, but there is no audio from the content on the tv. I have tried to power down the soundbar while it’s in this state, but the eARC connection causes it to power back on automatically when it recognizes the active input on the tv. The only way to reset the soundbar is to unplug it, wait for a few seconds and plug it back in. It works for 1-3 weeks and then it happens again. I’ve reached out to Klipsch support about this but they seem to be bewildered by the cause. I’ve done factory resets, firmware re-flashes, and changed the HDMI cable twice. Has anyone else experienced this and found a resolution, or does anyone have any ideas on a potential cause for the issue? I’m thinking I could use an optical cable, but then I’m limited on audio format support to Dolby Digital and not Dolby Digital Plus.

Have you tried optical yet, just for the trouble shooting? Thanks! Quote Link to comment Share on other sites More sharing options...

I tried optical as an alternative last year and ended up with a weird echo as sound was being output from my tv and the soundbar simultaneously even though I set the tv audio output to be External Speakers only. I’m willing to give it another go, but worrie that I’d lose support for Dolby Digital Plus (heavy Netflix user) by not using eARC. 1 Quote Link to comment Share on other sites More sharing options...

I’d normally agree with you except the noise only emits from the soundbar and not the surround speakers. I’ve experienced the squeal and pop noise from the surround 3 in the past and realized it was interference being caused by the Wi-Fi router. That has since been resolved by relocating the router. But you do have me thinking if there is a chance the transmitter for the Surround 3s are a potential cause? 1 Quote Link to comment Share on other sites More sharing options...

Well, the tv is connected via Wi-Fi, but it’s been my experience that interference yields pops and crackles. I’ve never had the soundbar fail to operate due to interference.

johndt Posted July 18, 2023 Share Posted July 18, 2023 I have the same problem and must unplug and then restart the bar to resume audio. I have no other solution, but I wonder if this problem is more widespread. Quote Link to comment Share on other sites More sharing options...

DanQ Posted July 21, 2023 Share Posted July 21, 2023 I have the exact same problem with my Cinema 800 and it has been this way since I bought it in 2021. I also have the surround 3s but I am using an LG C1 for my TV. I have seen this reported for the Cinema 1200 as well but I have yet to see a root cause or a fix identified. I have done troubleshooting with Klipsch support but nothing resolves the issue. Quote Link to comment Share on other sites More sharing options...
OO1 Posted July 22, 2023 Share Posted July 22, 2023 how is your router configured (both 2.4 ghz and 5 ghz) Quote Link to comment Share on other sites More sharing options...
DanQ Posted July 22, 2023 Share Posted July 22, 2023 I have 2.4 and 5 GHz wireless signals but I am skeptical that this is an EMI problem. Quote Link to comment Share on other sites More sharing options...

I have done troubleshooting with Klipsch support but nothing resolves the issue. That’s interesting. The Bravia A8H and LG C1 share the same panel, but they use different electronics for processing a/v signals. I feel like that makes our issues related, but can’t quite figure out the connection. It’s sad to hear that the 1200 experiences this issue as well. I may have to look at other options to enjoy surround sound at home. Quote Link to comment Share on other sites More sharing options...

I do have a wireless AP nearby (~6ft) so I turned the transmitter power down on both bands and will see if the problem resolves itself. The squealing problem is intermittent so it will take a while to test but I will post back with my results. Quote Link to comment Share on other sites More sharing options...

vihurricane Posted August 18, 2023 Author Share Posted August 18, 2023 Unfortunately, my Wi-Fi router isn’t close enough for me to test this using an Ethernet cable. I appreciate the suggestions, but I really think it’s something to do with the interaction between the soundbar and the tv. The issue only occurs during the Power On sequence when the the TV sends the Powe On Command to the soundbar via HDMI CEC. I have a sneaking suspicion that whatever app was last use on the TV output, some type of invalid signal when the TV power is on that causes the sound bar to glitch,”. Unfortunately, I can’t think of a good way to test and validate that theory. The good news is Klipsch has offered to send me a replacement because it sounds like there’s been other issues with the 800 series. I do appreciate their customer support.

vickeyduck Posted November 26, 2023 Share Posted November 26, 2023 I'm facing an issue with my Cinema 700 system (Costco version of Cinema 800), which is connected to a Sony X91CJ TV. Recently, I added a pair of Surround 3 speakers to the setup. However, I've been experiencing audio issues even before integrating the Surround 3, and this persists when WIFI is disconnected, suggesting that signal interference is unlikely to be the cause.
