Xonar DGX, no sound

no_sound · May 7, 2017, 3:52pm

Hi,
I have trouble getting sound even though the soundcard is recognized.
System: Leap 42.2, KDE, fully updated, no external repositories added
Soundcard: Asus Xonar DGX
Setup: Headphones are plugged in the back, no frontpanel installed

Sound is working fine on Windows 7 and Archlinux.
Also the built-in soundcard works fine.

What I tried:

Yast: The quick-setup tried to use snd-virtuoso instead of snd-oxygen -> I deleted /etc/modprobe/50-sound.conf
Forced loading of snd-oxygen by adding an entry in /etc/modules-load/ -> module is loaded and card is recognized by pavucontrol and pactl
Activated and configured card through pavucontrol -> volumebar moves if music is played through Amarok or Firefox

I suspect the card sends the output to the frontpanel. Is there a way to verify/change that?


cat /etc/modules-load.d/50-sound.conf
snd-oxygen

Greetings,

This may not be helpful but what Desktop Environment are you using?

KDE has a great management for sound output. That combined with the KDE Audio control you can drag and drop audio streams to specific sound devices.

Admittadly, that may not be your issue.

I do have an issue with one machine that plugging in headphones doesn’t automatically switch the sound from speakers to the headphones. Not sure if it is a hardware or a driver issue but I can manually select Headphones output using Pavucontrol.

Hope that helps, at least a bit.

This may not be helpful but what Desktop Environment are you using?

KDE

KDE has a great management for sound output. That combined with the KDE Audio control you can drag and drop audio streams to specific sound devices.

All streams are configured to use the DGX card, in Pavucontrol and the KDE tool.
It is set as default as well and configured as “Analogue Stereo Duplex” under the “Configuration” tab and the port “Headphones” is the only one to choose the “Output Devices” section.

I do have an issue with one machine that plugging in headphones doesn’t automatically switch the sound from speakers to the headphones. Not sure if it is a hardware or a driver issue but I can manually select Headphones output using Pavucontrol.

I do suspect it is something like that. On the other hand it does work in Archlinux and Windows 7 without changing anything on the hardwareside.
Just to clarify: The headphones are plugged in the stereo output on the back of the card (the green one which is for left and right in 5.1-mode, i think). Also i checked if the sound is redirected to any other analogue port, which it isn’t. I have no way to test the digital output.

I searched for differences in the configuration on Archlinux and Leap but the only one I could find
is the index of the card and the field “Subdevices” in the output of aplay -l.


Leap:
aplay -l
card 0: DGX [Xonar DGX], device 0: Multichannel [Multichannel]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: DGX [Xonar DGX], device 1: Digital [Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
----snip----

Archlinux:
aplay -l
----snip----
card 2: DGX [Xonar DGX], device 0: Multichannel [Multichannel]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: DGX [Xonar DGX], device 1: Digital [Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I don’t know if that could cause the problem.

From what I can tell with my system, the card number doesn’t matter. I really think it sounds like a KDE configuration issue.

Have you gone into the KDE Systemsettings > Multimedia > Audio and Video settings and looked at what the priority of the output devices are there? Perhaps adjusting the order will change what output device is used.

I have multiple devices and this is how I set their priority to ensure that sound goes where I want it to go. I also have it set to not automatically change this: Systemsettings > Multimedia > Audio Volume > Configuration Tab

Hope this helps,
-Nathan

Solved it.
Alsamixer is able to switch the output from the frontpanel to the back side (press F6 to select the soundcard).
Thank you for your support.
