Linux: No HDMI Audio with Intel UHD Graphics 630

[Major-Mayer]

Hi everybody,

I have the problem that I don't get any sound from my Intel UHD Graphics 630 (Core i5-8600K) when connecting a display via HDMI.
Video is working without any problems, but the display just doesn't appear in the audio device list:

As you can see, other devices like my AMD graphics card work without any problems.

I am using Manjaro Linux on Kernel 6.6.32, so pretty up to date:

Operating System: Manjaro Linux
KDE Plasma Version: 6.0.5
KDE Frameworks Version: 6.2.0
Qt Version: 6.7.1
Kernel Version: 6.6.32-1-MANJARO (64-bit)
Graphics Platform: Wayland
Processors: 6 × Intel® Core™ i5-8600K CPU @ 3.60GHz
Memory: 31.2 GiB of RAM
Graphics Processor: AMD Radeon RX 6800
Manufacturer: Micro-Star International Co., Ltd.
Product Name: MS-7B46
System Version: 1.0

The kernel driver is i915

```

00:02.0 Display controller: Intel Corporation CoffeeLake-S GT2 [UHD Graphics 630]
       DeviceName: Onboard - Video
       Subsystem: Micro-Star International Co., Ltd. [MSI] Device 7b46
       Kernel driver in use: i915
       Kernel modules: i91

```

Any help would be very appreciated.

Edit:

Maybe some logs could help for easier debugging:

So as you can see, the Intel audio device is not listed.

It's also not the cable, because when I plug it into my AMD card, the video + sound works just fine.

hello there Mayer

I noticed that the video is working fine, but the display doesn't appear in the audio device list. Other devices, such as your AMD graphics card, work without any problems. The kernel driver in use is i915, and the Intel audio device is not listed in the logs.

Given this information, it appears to be a specific issue with the Intel audio device on your system. Since the cable works fine with your AMD card, it's unlikely to be a cable issue.

To troubleshoot further, you may want to consider checking for any driver updates or compatibility issues with the Intel UHD Graphics 630 on Manjaro Linux. You can visit links below which other customer reported similar issues:

• No audio from port of external monitor connected via HDMI cable 
• HDMI output profile unavailable, No HDMI Audio 
• Sound not working properly after using HDMI output
• HDMI/DP output device not recognized

Additionally, you could try reaching out to the Manjaro community or forums for assistance, as they may have encountered similar issues and can provide more tailored advice for your setup.

Hi Williams,

I appreciate your help, but actually I wanted to delete this thread, since i've found a solution myself (It was not possible, since the thread was marked as spam).

It turned out that sound via HDMI actually works, the problem was just that the profile was hidden in one of the devices, which I didn't expect ("Internes Audio Analog Stereo" or "Internal Audio Analog Stereo"):

Using this profile, the sound actually comes through.

Thank you anyway 🙂
