That is a clever workaround. Somehow it seems ironic, given that I ran Squeezelite for years before Roon existed, and now it’s being suggested as a workaround for Roon flaws. LOL. Thanks @Nickpi.
Have taken this up over at this thread, and the problem appears to be with RoonBridge. It has some known issues that are being investigated now. Will wait for a fix. Thanks.
