HDMI audio output?

Hello

Has anyone gotten HDMI audio output working with the framework?

I have tried different monitors/TVs. It doesn’t show up as a sound option in Windows 10, and it doesn’t transmit anything. I’m using the same HDMI cable I use with my camcorder for video capture where it carries stereo 16 bit/48 KHz PCM audio.

I installed the driverpack on this website, and also tried driverpack solution too just to see if anything was missing. I am using the USB-C/HDMI adapter that comes with the laptop and plugs into the side, not my own.

Thanks!

Just tried real quick, and my XG270HU monitor is recognized as a sound output for Windows without issue, either over the HDMI expansion card or through my generic USB-C hub.

Does this occur as well with the Beta driver bundle here: Public Beta Test: BIOS v3.03 + Driver Bundle 2021_08_31

No change.

I checked device manager. When I tell it to show hidden devices, intel hd audio shows up. Which I imagine is HDMI audio, but windows update cannot find a driver for it. Same if I use Intel’s own tool on Intel® Driver & Support Assistant - it says I already have everything, besides some unrelated bluetooth driver that could be updated. I’ll keep digging.

Thanks!

A hah, fixed!

I removed the Intel High Definition Audio manually by right clicking it and going uninstall, after going view → show hidden devices in device manager. I went to Download Intel Drivers and Software and grabbed the beta driver for the Intel Iris XE for my version of windows 10, and it worked. The driver support/assistance page/application was useless, but the Download Intel Drivers & Software page led me to the ability to manuallyu download & install the driver I needed and it worked. I have HDMI audio now! I hope this helps someone else.

Thanks!

No HDMI audio for me either on Windows 10 or on Ubuntu 21.04. I tried Louis’ fix and did not work for me. I do have a workaround though…I have a Lenovo USB C Hub w/ a HDMI port on it. This works fine on my Framework and I get audio over HDMI on both Windows 10 and Ubuntu 21.04. Hope a fix is coming for the Framework HDMI port audio as I was hoping to get away from carrying around a hub by being able to choose my own ports.

I also get no sound via the Framework HDMI card on some devices. It works on my monitor and fairly old Samsung TV, but it doesn’t on a newer TV (LG C1) and older AVR (Yamaha RX-V781). Doesn’t matter if i output via the AVR or TV speakers. It works with my deskop PC (nvidia HDMI output).

I tried multiple GPU drivers (101.1121, .1404, .1631) and even upgraded from Win10 to Win11 in between. It works from a USB-C HDMI dongle, but of course thats not a solution.

When i’m connected to the AVR, it just doesn’t play sounds. When i’m connected to the TV an error comes up, when i try to play test-tones “Failed to play test tone”.

Any ideas?

I too am having difficulty with my HDMI. I can get picture on my TV, but no sound. I have reported this and they are sending me lots of tests to do. However nothing seems to work. I suggested that they send me another HDMI port. But they say i have to do more tests.

Has anyone got it working OK?

My old Toshiba laptop has no problems with HDMI, I can play video on the TV from that laptop. With no sound issues.

They now are sending me another HDMI socket.

We will see how I get on with that.

Unfortunately that HDMI socket arrived today, and is worse than the one I got previously. So I have told them, and sent a photo of the image on the TV. And there is no sound to the TV.

I hope i get it sorted soon

It’s been working perfectly fine for me strangely.

Very good Shiroudan.

I hope mine gets sorted soon.

They sent me some more tests to do. However the original HDMI socket is now as bad as the new one, in each socket.

The old Toshiba is working fine.

They are now sending me another HDMI attachment.
