I have recently purchased the q990c and it seems there are some factory issues with the right rear speaker. The speaker is producing a "crackling" sound inwhich is not apparant in the left rear speaker. This crackling sound is only apparent when I played specific types of music/notes (e.g. Minecraft by C418). I have tried many solutions and none seem to fix or alleviate this issue.

Here is a list on what I have tried:

1. factory reset the speaker by holding the + and - volume buttons for more than 5 seconds

2. connected to my smart things app and conduct a firmware update

3. played different types of music/movies in different sources (bluetooth, HDMI eARC, etc.)

4. resetting wifi connection

5. relocating the rear speakers and sound system

6. switching off and on the power of the rear speaker

Is there anything I could do to fix this? I only just bought this soundbar set 2 days ago and I prefer not to repack the whole set and return it...

Here are the soundcloud links to show the issue (the issue is in the right speaker):
