Wiim pro plus & Leak Stereo 130 optical sync issues

[Urfe]

I'm having an issue with a Wiim pro plus hooked up to a Leak Stereo 130 via an optical connection. The audio drifts slightly in and out of sync with my other Wiim devices when using Airplay speaker groups. My other 7 devices are all pros, the only one with a sync issue is my pro plus. None of my other devices have sync issues. I'll fix the sync using the calibration tool, it will work for a min or two... and then drift slightly out of sync again.

Has anyone else had an issue with this hardware combination? I previously had a Chromecast Audio setup for all these same speakers and the sync worked perfectly with optical (no calibration too lol), so maybe it's a Wiim compatibility issue? I have a bunch of systems and it's definitely the pro plus that is drifting.

Have you tried using one of the other Pros in place of the Pro Plus in the Leak system? If that does not improve the situation then that would suggest there is something going on with the DAC in the Leak. (Since you are using an optical connection to the Leak that means it is using the Leak's DAC.)

OTOH, if using a Pro in place of the Pro Plus fixes the problem that suggests you need to file a warranty ticket on the Plus with WiiM.

I agree with @mlsstl's suggestion.

I also read that the Leak Stereo 130 has a direct mode.

Please try connecting the Pro plus and Leak Stereo 130 with RCA cable, and see if turning on direct mode solves the sync issue.
