Connecting a MacBook Pro to WiiM Ultra?

What would be a possible way to connect a MacBook Pro to my WiiM Ultra? The only output on the MBP is USB-C.

What I’m trying to achieve is to run REW on the MacBook and measure the output from the Ultra -> amplifier -> speakers.
 
The USB or HDMI input won’t work? Toslink is what I should opt for?
The Ultra doesn’t have USB audio in, and its HDMI is for connection to a TV HDMI ARC socket, so optical is your only option (analog line in aside).

You can try Bluetooth first. It is good enough for room correction.
 
Good idea. I also have a cheap USB-C to 3.5mm headphone mini DAC that I could use, but it’s probably not even better than BT.
Or try a cheap usb c to toslink converter or a ddc, various models have been suggested around the site to look at
 
You can definitely use the HDMI input on the Wiim Ultra with your MacBook to transmit audio, assuming you're not using the HDMI output for anything else. I'm going from my MacBook to a Thunderbolt hub, then from the Thunderbolt hub to my Ultra via HDMI for audio. I'm not sure about the requirements for REW, but if all you need is audio output, then this should work fine.

How is that possible? The MacBook don't provide ARC on HDMI output and the WiiM Ultra only support HDMI ARC on input.

HDMI audio is imbedded in the HDMI video signal, while ARC is a completely separate signal on different wires in the HDMI cable. So maybe your thunderbolt hub do the conversation? Else only the TV normally do that.

I've tried it. It works fine. ARC stands for "Audio Return Channel" meaning it's a two-way transfer of audio between the two devices. In this case, we don't need two-way communication. HDMI is able to transmit audio without ARC, and that's all the user is trying to do here, as I understand it. If I'm misunderstanding and the goal is to get audio FROM the Wiim Ultra TO the Mac via HDMI, then yeah, that's not going to work. If all they want to do is play audio FROM the Mac to the Wiim Ultra, then HDMI will work just fine.


What Is HDMI ARC and eARC?​

The often-overlooked ARC stands for "Audio Return Channel," and ever since the HDMI 1.4 standard was introduced, ARC has started rolling out to new TVs, soundbars and A/V receivers. This protocol offers two-way communication between devices over a single HDMI connection. Essentially, the HDMI ARC port lets you use HDMI as both an input and an audio output.

An example of when you need ARC (or eARC) would be if you have an AV receiver connected to your TV and that AV receiver has HDMI inputs. You would have an HDMI ARC channel on the receiver that you would connect to the TV. That way, the TV and any devices you have connected to the TV's HDMI inputs can transmit audio to your AV receiver, but the AV receiver and any HDMI devices connected to it would be able to transmit audio BACK to the TV via the same ARC connection.

This is actually why I've always been confused by the inclusion of ARC on the Wiim Ultra. They don't expose HDMI as an OUTPUT, so they're really not making use of the ARC functionality. If they're offering ARC, then I should be able to choose HDMI as an OUTPUT and send the audio from any of my other sources to my TV speakers, if I wanted to.

Sorry, I think you are misunderstanding it. ARC is not two ways. It return the audio signal from a TV to another device (e.g. a soundbar) after the TV has extracted it from the digital video signal (maybe received on the same HDMI cable).

The MacBook cannot output audio on the ARC line and the WiiM only support ARC input, not HDMI audio imbedded in the video signal.

Well, damn. I was all excited to prove you wrong so I connected my MacBook to my Wiim and it doesn't show up as an audio output. It's strange, because I swear I was running that way for a while before I changed my system recently. Then again, I have a variety of adapters and docking stations, so it's possible whatever method of connectivity I was using at the time was handling passing the audio. If I get time, I'll have to try with my docking stations. Maybe I was going Thunderbolt to docking station to Display Port to HDMI or something weird like that?
