Sound gone after installing asus xonar essence stx


First of all, let me refer to the thread I opened the 7th of November 2014:

I managed with your help to get sound to hdmi working in xbmc (not in kde, but in this htpc that’s not too important).

To get better sound, I installed a (new) Asus Xonar Essence STX, but I had no luck there. Not only there’s no sound coming from the new card (except for some clicking when I enable/disable the card in Yast), but I’ve no sound whatsoever now.; nothing.

I disabled all cards again in Yast, removed 50-sound.conf from /etc/modprobe.d , enabled the hdmi-card as the only one, and rebooted - nothing. Not even a test sound from within Yast.

Hardware is seen:

/etc/default/grub still has GRUB_CMDLINE_LINUX=“”, as was advised in the november-thread I referred too, and /etc/modprobe.d has

/etc/modprobe.d # cat radeon.conf
options radeon audio=1

What can I do to get proper sound, preferable choosable between hdmi and the Xonar?

So before you do anything, I have to ask - why did you buy a new sound card to improve sound quality when there is no D-A conversion going on?

My point being, at no point during the HTPC → HDMI → TV/Audio system is there a Digital → Analog conversion where the quality of the components would have any bearing on the quality of the sound. You’re going all digital and… bit is a bit is a bit :slight_smile:

I get your point, but I want hdmi just to be one of the 2 outputs. The other should be the Xonar, which is connected to either a very good headphone or a high end hi-fi system. Then I can choose between both, depending on the nature of the sound to be represented (just the daily news, or a Chopin-etude). Of course, if I get the Xonar working, maybe hdmi isn’t needed anymore, but that’ s another issue.

I have no experience with the hardware mentioned. Having typed thou, sometimes experience with specific hardware is not needed. My own assessment on this forum is 90% of the time sound problems are associated with understandable difficulty in navigating GNU/Linux’s relatively complex flexibility (with a miriad of settings) that is provided wrt setting up sound devices.

What could help is more information, in a format different from what you provided. Please, with PC connected to the Internet, when the sound card is installed, run in a konsole or xterm the diagnostic script:


Select the SHARE/UPLOAD option when prompted. That will upload the sound configuration to an alsa hosting site, where the link can then be shared so users trying to help can better see the PC’s sound configuration. After the script has completed, it will provide in the konsole/xterm the URL of the uplaoded information. Please run the script and post the URL here.

Maybe after looking at it we will see something obvious.
