Switchology will get me every time

[GTW]

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!

Tell me Jedi Grand Master, how do you do that.

After a day of silent frustration, I observed that my firestick was in HDMI port 3 of the projector.

My brother in law gave me his old computer years ago to rip my CDs. I'd never had a computer before. It had Ubuntu 7.04 on it (so it will have been around 2007). He plugged it in, switched it on and told me not to phone him, to use Google instead.

After he'd gone I put a CD in and the sound wouldn't work. Mindful of his instruction not to phone him I searched the Web.

Over the next 2 or 3 weeks, trying to fix the sound on my own, I joined forums and IRC channels where learned all sorts of fancy linuxy stuff. I was editing start up scripts, inserting kernel modules, and patching source code. I even tried recompiling the kernel. I felt like the girl with the dragon tattoo with all these lines of console output flying up the screen.

But still the sound wouldn't work. So I gave up and phoned him. With a sigh he came over. Took a look at the computer and told me that the speakers should be plugged into the green hole, not the blue one.

The reason I had to do it that way is because the Audio Return Channel never seemed to work. After enabling HDMI-CEC at both ends, enabling HDMI ARC at both ends, rebooting at both ends, and having both sides auto-identify on both ends, sound did not connect. It wasn't until the toslink was added did the stream connect. I thought the whole point of HDMI ARC was to eliminate the need for fiber optic, yeah that's what salvaged everything at the end.
