I think some have said unplugging their amp from the mains for a short while has fixed such issues.
Even though yours is brand new, worth a shot...

Hi Team,
Please submit a feedback ticket to us if you're not receiving the subwoofer signal. This will allow us to retrieve the diagnostic log from your device, which will greatly assist in troubleshooting the issue. If you have already submitted a ticket, please provide the ticket number so I can escalate the issue to our team.

So do you hear the high pass filter acting on the main speakers?
The high pass filter yes. The sub volume doesn’t do anything. High pass filter decreases and increases bass from the main speakers
Can you tell us more about the SW model and connection status?
(We don't know how familiar you are with audio equipment.)
Yea didn’t mention that. Pretty familiar with it. DJ and radio producer since forever , been in studios and dealing with sound equipment most of my life
Sony SA-CS9 sub
I don't think you need any basic advice, but is the connection and setup of the SW like this?
WiiM amp (Sub out) >> (LINE-IN) SA-CS9
[SA-CS9]
Level > 50%
Cut off freq :200Hz
Power save: off
Also, have you confirmed that there is sound when other devices are connected to the SA-CS9? If everything is fine, it may be an initial defect of the AMP.
All ok. But no other devices connected to the sub. Speakers connected directly to wiim amp and they are working fine

Have you used the sub previously?
No. it’s brand new. Trying to get hold of another sub to confirm if it’s a sub issue or amp issue. Sub is powered on fine though

OK probably a daft question but have you tried adjusting the volume on the sub? I did say it was a daft question.
Haha. Yes. Did everything I could to troubleshoot this issue. I just want is defective. The sub or the amp
Plug you phone with a jack <-> RCA cable into the subwoofer. Final proof if it's broken or not.
Alternatively, you can check the operation of the SW in this way.

Does it make a sound when you touch the tip of the plug of the RCA cable connected to the SW?
