Audio-Out With ASUS Xonar DX

English Hardware
1

I am using openSUSE Leap 42.2, 64-bit. The PC has a dedicated audio card: ASUS Xonar DX.

I am unable to get audio-out to the front panel of my PC whenever I plug in my headphone into the front headphone jack (the green colored one).

With Windows 7, the only way that I can switch audio-out from the rear panel jack to the front one is by using the software supplied by ASUS. Apparently the Xonar DX is unable to detect on its own when a headphone is plugged into the front panel headphone jack and switch the audio channel to that jack.

ASUS does not have a utility for Linux like the one offered for Windows. Does openSUSE have a way to tell to the dedicated audio card to switch audio-out from the rear panel to the front one?

Install if you already have not

pavucontrol

See what it says you plug into the front. See if it is detected and you can then switch output to there if it is

3

Did as instructed. In the “Output Devices” tab I cannot understand how to activate the front headphone jack… There does not seem to be an option for that.

4

If you plug in the front jack it does not show in the list???

5

No. Under the tab “Output Devices” I don’t see anything that hints to the headphones front panel jack.
And there is not audio out to the headphones, anyhow.

Would not expect output unless it is selected

So this appears to be a hardware glitch of some sort,

follow trouble shooting instructions here

Does alsamixer or amixer provide any useful options ?

I vaguely recall many user requests for support on these ASUS Xonar Dx’s, and I do not know if they are fully supported in GNU/Linux. Can you run the diagnostic script (in a konsole or xterm) as a regular user with your PC connected to the Internet (with your headset plugged in to the jack that you wish to get working) :


/usr/sbin/alsa-info.sh

select the SHARE/UPLOAD option, and let the script run to completion. After it completes it will put a web-address/URL in the konsole/xterm that you are to share with those trying to help. Please post the web-address/URL here on this forum. Maybe that output will provide some ideas as to a possible way to address this problem.

You seem to have sent me on the right track…
I ran alsamixer as you suggested. The volume control for *Front Panel *was set to “MM”. I pressed the letter “m” once and the “MM” turned into “00” and I had audio out to the headphones!
When I want to re-direct audio out to the rear speakers again, I just hit “m” once and voilà: The headphones are muted (“MM”) and audio can be hard through the rear speakers.

Excellent news .

If over time running alsamixer is too irritating, another possibility would be to use the command line “amixer” to change that same setting. You do thou need to figure out the exact syntax. Once figured out, then put the amixer command into a file, make it executable, and put an icon on the desktop that runs the executable file. Also put a second icon on the desktop (that runs a second executable file with the command to set back). That way you have 2 icons on the desktop that let you easily switch back and forth.
