My Subwoofer has started making the crackling noise. When the content has a deep bass sound, the crackling has started getting real nasty!
It seems like this has been a widely complained issue with Samsung's HW-Q90R soundbar as well. Though there are like hundreds of people complaining (literally! the Samsung forum, Reddit, AV, and AVS forums are filled with such posts and threads), it is not clear whether Samsung really attempted to fix the issue.
There is even a petition appealing to Samsung to acknowledge and fix this terrible design flaw!
I have tried a bunch of things:
- Factory Reset the Soundbar.
- I already have the soundbar on the latest available firmware.
- Reser the ID for the Subwoofer and re-paired it with the main Soundbar
- My 5 GHz WiFi is already on a lower signal (44)
I cannot move my WiFi router any further away - it's not like it is right next to the Subwoofer or anything! I tried to change 5 GHz channel's bandwidth from 80 mhz to 20 mhz, but this reduced my WiFi speed big time, so had to go back to 80!
This constant issue is completely killing the soundbar for me. At this point, I really, really want to dump this soundbar unless I can figure out a solution.
Any suggestions on things I can try to fix this issue?
If you are using mesh wifi, also try a different frequency for the back haul, or use an ethernet cable.
For some people, the back haul connection was more of an issue than the router wifi itself.
@InTheBay Did this issue every get solved for you? I just purchased the 950T and am exeriencing the same issue. I thought it was a hardware issue so I exchanged it for a new unit and the same problem occurs instantly.
With my first unit i only noticed the sound when playing Dolby Atmos movies but now I am experiencing it when playing music.
The issue seems to have disappeared for now. Not sure which of the below did the trick:
- Updated the soundbar to the latest firmware version
- Changed Soundbar channel to 1. Turn soundbar on, press and hold sub volume button on the remote. Use the up and down direction buttons to change channels.
