[Bug Report] WiiM Sound: "Stereo Group" option missing in Google Home app

[lePaulo]

Hi,
I want to report an issue with WiiM Sound and the native Google Home Stereo Group feature (distinct from Google Home speaker groups).

Context:
Google Home allows creating a native stereo pair ("Stereo Group") between two compatible Cast devices, assigning Left and Right channels at the Cast protocol level.

The issue:
With WiiM Pro, the "Stereo Group" option is available in Google Home and works correctly.
With WiiM Sound, the device is visible in Google Home, but the Stereo Group option is simply not available for it.

Summary:

Device	Visible in Google Home	Stereo Group option available
WiiM Pro
WiiM Sound

This suggests the WiiM Sound is not exposing the correct Cast capability flag that enables the Stereo Group feature in Google Home.
Is this a known limitation? Is it something that could be fixed at firmware level so the WiiM Sound properly advertises stereo pairing capability to Google Home?

Thanks

You should submit a ticket to WiiM via the more/feedback section in the WiiM home app so they can inspect your device logs.

Strangely, although I’m sure I’ve seen and used it in the past, I can’t seem to find the stereo option in either of my iPad or Android phone Google home apps for any of my WiiM devices.

Yes. To find it you have to select your device in the Google Home app, then the "Audio" option, and there you're supposed to get the "Pair stereo" option - which I have for my WiiM Pro, but not for my WiiM Sound.
I'll follow your advice and submit a ticket then.

I have a Sound Lite, and the Google Home app also lacks the "Stereo Pair" option under Device Features > Audio.
