I have a WiiM Pro Plus connected using analog cables to a pair of Bang & Olufsen Beolab 6000 powered/active speakers. Every hour or so (it's not regular), the speakers "pop". It doesn't matter whether we're using a streaming or analog source (there's a Rega P3 turntable attached to the Pro Plus). This didn't happen with the WiiM Mini the Pro Plus replaced. It seems to be a common issue. Any thoughts? I tried switching the SPDIF Output Resolution to "Fixed Resolution" today to see if that helps.
