Intel NUC - Sound output only through HDMI
« on: April 03, 2015, 06:36:38 pm »
I have acquired an Intel NUC for my current project. But this NUC doesn't have a line output like regular computers. Sound is delivered via HDMI. I have tried this:

But that won't work with my 15" monitor with resolution 1024x768.

So do any of you have a tip or a good advice for me? Maybe a cheap USB soundcard like this: http://www.ebay.com/itm/281619178703

So what doesn't work?
I had one of those and while it worked I could do almost any resolution.

I also just plugged my computer speakers into the audio jack.

There simply is no picture. I have another one but without the audio output, and that one works. Well, there may be a defect one I have got though...

The nuc might not like the adaptor or its bad.
Have you tried it on something else with an HDMI out?

Also I would try an active convertor.
One that uses a a USB port or wallwort to power it.

I bought this one for an android stick and it work well.

you must install amixer and make the following call right after booting and before call of mame:

sudo amixer -c 0 cset numid=3 1

uuuups!

my posting was under the assumption that we are talking about and raspi running with linux.

I re-read your post and of course you talking about an Intel NUC. From some pics on the internet it seemed that it has and 3.5mm audio connector.
Just for the case that this is right and the box is also under linux, my previous posting may still be valid.

Otherwise, just ignore!
