I just received my Ultra 2 days ago, and was struggling to get firestick audio into the digital preamp. My 4K projector has a virtual switch to enable optical, but the Ultra wasn't receiving.
After a day of silent frustration, I observed that my firestick was in HDMI port 3 of the projector. After reconnecting to HDMI port 1 (HDMI ARC), optical came alive.
There's nothing wrong with the supplied speakers on my 4K projector, but having it in the entertainment system is better. The AV sync tools and room fit tools matched it all up in seconds.
I'm a vintage audio guy, this Ultra digital interface gave it all a new lease on life.
Thank you WiiM!
