Polk magnifi max SR

Options
I have some troubles regarding Wi-Fi connectivity and the left SR1 wireless surround speaker that continues to make a crackling sound no matter what I try.

When setting-up the magnifi max I couldn't add the device to my Google home app. But when I go on any mobile device to YouTube and want to stream it allows me to do that through the embedded Google chromecast in the soundbar. So something is going on here but I can't seem to figure out what.

The left SR1 wireless surround speaker I already brought back to the retailer for repair. Once it got back it seemed to work for a while but after some time it started to make the all to familiar crackling sound like it did before. To me it looks like a syncing problem but I can be wrong I read here and there online that this is a regular problem with the SR1 surround speaker.

Any ideas on this?
