Radial play and clicking noise in the outer ring of the Amp Pro volume knob

[hgb]

Hi everyone,
I have a WiiM Amp Pro and I notice some radial play in the outer ring of the volume knob (around ~0.5 mm upward).
It’s directional (top/right only) and comes with a small contact clicking noise when just touched laterally (just touched, no pression). The encoder itself works fine; this seems limited to the outer aluminum ring.
I’d like to check:

• Do other Amp Pro owners experience the same thing?
• Or is your volume knob completely solid with no lateral play/click?

Trying to understand if this is normal tolerance or a unit-specific issue.
Thanks for your feedback!

It‘s a plastic knob, not aluminum. It‘s stuck onto the axis with a rubber link. The clicking you have mentioned is probably a rubber squeeking/snapping noise. Nothing that will compromise the functionallity. Not nice bit that‘s just the price for the price.

Apologies. You are right that is a plastic ring. Is that radial play and rubber squeeking/snapping noise typical on most units?

My Ultra doesn‘t have it. But I‘ve read of others with the same issue on this very forum.

Yes, if I (gently) "wobble" the amp pro volume knob it moves by maybe 0.5 mm and makes a clicking sound.

Attached a video of play/clicking noise. Is it common on most Amp Pros?

Does pressing the corner pause or resume music playback? If so, that's normal.

No. Pressing the center button does that. For the ring it is a radial play (am not even pressing it, just making a contact), bottom and left part of the ring are fixed but not upper and right part of it, like if it was slightly broken or something

I checked my Amp Pro. On mine, the bottom part of the knob has the most play.

There seems to be some variation between units, but I guess this is likely within the normal range. If you're concerned, I recommend submitting a ticket so our team can review your video.

Many thanks for having taken the time!
Indeed seems similar ring play but weirdly not similarly localized
