HW-Q90r subwoofer distortion

JUMP TO SOLUTION

Hello,

 

I purchased the Q90R soundbar a few days ago and so far so good.  But I have had a few occasions where there is some noticeable distortion from the subwoofer.  I haven't been able to pinpoint specific content as it just seems to happen randomly.  I'm suspicious of a bug or Bluetooth issue but no way to confirm.  

I confirmed that I have firmware 1008 installed and otherwise have default settings.  Soundbar is connected via hdmi arc to my Samsung qled. No issues with the rear speakers as far as I can tell. 

Just wondering if maybe I have a lemon.

This thread can be closed as I am fairly certain that the issue is resolved.  

After upgrading my HDMI cables I decided to relocate the subwoofer closer to my TV stand and reorienting so that it fired towards the center of the room rather than into the wall.  Seems like that did the trick as I've not had the distortion since.  I suspect that something is interfering with the wireless signal but don't have a measurable way to confirm.

Are you able to describe the distortion? Is it a static type sound? http://www.samsung.com/us/support/troubleshooting/TSG01109855/

I wouldn't say that it's a static sound. More like a low, dull and hollow sounding bass frequency at a time when I would expect more of a bold punchy sound.  It's entirely possible that it could be due to the signal being sent.  It doesn't happen often, but I have had it happen from both my FIOS tv and Xbox One X sources.  And I have tried HDMI into my Q90 qled using arc as well as going directly into the soundbar.  

The sub is about 4-5 ft from the soundbar so I don't suspect distance is the problem.  If I can I will try to capture an audio sample and upload to YouTube for reference.

That would be amazing! If you don't mind providing a sound clip, the model of the TV and the software versions of each? I will be able to research this further for you.

Have you tried using a different cable and have you tried a different source?

I can confirm that the distortion occurs on other sources such as Xbox One gaming and my Verizon TV FiOS.  Regardless of source it seems to be a random occurrence.  

As far as cabling goes I have not tried different cables.  I am currently using the HDMI cable provided with the Q90R soundbar.  And the Xbox and Verizon devices are configured with their included cables.  

I will purchase a better quality cable to replace the HDMI cable connecting the ARC ports between the TV and soundbar to see if there's any improvement.

I replaced the cable today between the sound bar HDMI arc output to the TV HDMI arc port 3.  Unfortunately I did experience the issue again shortly thereafter during some general TV programming. 

In case anyone is wondering, the new cable is one of the Belkin high speed HDMI 48Gbps.

The next step would be service, since you did say that you just recently purchased it you do have two options you can send me a private message with your full serial number we can get you set up for service, or you can take it back and try for an exchange?
