Wintel Mini PC HDMI Not Working With XMC-1

[bvanfleet1]

First, sorry if this isn't the best place for this, gotta start somewhere.

I'm working with my dad on his home theater (he's using the XMC-1 connected to a Sony projector). He recently bought a Wintel mini PC that's running Windows 10 on it. However, it's not syncing with the XMC-1 properly. Initially we were having issues with it not working entirely. However, it's currently progressed to just the audio not working over HDMI.

We've isolated to the XMC-1 by connecting the PC to the projector directly, which worked without issue there. We've also confirmed that audio works when the XMC-1 is bypassed.

Last night we completed a round of updates to the PC and played with the startup order. The order we used to get video playing was: 1. Begin with everything turned off; 2. Start the PC; 3. Start the XMC-1. Outside of this, both the XMC-1 and the PC seem to work fine (my dad's been using the XMC-1 for some time with different accessories).

Has anyone else had any luck with Windows 10 on a mini PC and an XMC-1?

Hey bud,

So there are many variables to consider, but what comes to mind when reading your issue is whether the HDMI version of the PC supports the HDCP version supported by the HDMI card you have installed in your XMC-1.

The lack of audio suggests that perhaps an issue with copyright protection compliance exists.

That said, I have some fairly complex HDMI configurations happening with my XMC-1 and it is not without it's quirks. Especially when you have to use HDMI converters to downsample content for other HDMI/HDCP versions, Ambiglight clone setups (fancy LED backlight lovelyness), etc...

Anyhoo, best of luck!

My W10 HTPC works fine with the XMC-1. First, I would check out the sound device configuration. I recommend the old sound control panel, not the new settings panel that is useless/incomplete. Not sure what variation of W10 you are on, but I can reach that through:

Settings->System->Sound->Sound Control Panel (on the right)

Check out the HDMI audio device properties. The "Supported Formats" tab will let you know what was negotiated. Hopefully you'll get 8 channels, HDCP, HD audio formats, etc. The Advanced tab has a button for testing output. After closing the properties window, you can use Configure to make sure the channel count and whatnot are correct.
