I would like to test the audio side of my graphics card (Radeon HD 5450), but how to activate it? In Audio settings of Linux system it is recognized ("HDMI Cedar audio"), but cannot be activated - the only option to choose is 'OFF'! I'm sure someone here told me that the audio of graphics cards is supported in Linux....
I have also a Envy24Ht card and it can be chosen, but it still doesn't work, not even with the latest kernel versions (4.14.20, 4.15.4, 4.16.0-rc2). BTW, also the 'memory bug' which prevents from using the whole RAM with RTL 8169 is still present in all those kernel lines...:-/

Re: HDMI audio of graphics cards
Have to ask the basic questions to start.
Is your Monitor HDMI capable and are you connected using the HDMI port of your video card ?
Can you try with my latest kernel (4.15.5).It is working for me (Radeon RV620) .

The Radeon HDMI sound support is built-in so no modules needed .
Just needs to be configured in Sound preferences to be Digital Stereo (HDMI) output and default device for sound output
in the Output section of Sound Preferences .

Re: HDMI audio of graphics cards
No... I will have to use a HDMI adapter with a separate audioconnector to get the sound to my monitor which has only DVDI/VGA connectors and a 3.5 mm sound plug. But I suppose the cabling does not effect directly on the available options in sound prefs...?Spectre660 wrote:Have to ask the basic questions to start.

I downloaded it and tested... No change.Can you try with my latest kernel (4.15.5).It is working for me (Radeon RV620) .

The problem is that there is nothing to select... There are no settings profiles available for Radeon sound, only 'off', See below:Just needs to be configured in Sound preferences to be Digital Stereo (HDMI) output and default device for sound output

Re: HDMI audio of graphics cards
Apparently HDMI needs EDID info from the Monitor about both its Video and Audio capabilities to set both signals. So if it is not getting any audio capability info from your monitor it will not enable the audio.
