Bug Description

Since I upgraded to UBUNTU 14.10, I finally had to reinstall ubuntu for half actualiazción error, the computer has been moved. Appear either audio controls on the system configuration, but no sound.
Found that:
is using the sound card (Asus Xonar) and not the motherboard, so it appears in Sound settings.
the speakers are on and in correct volumes.
In windows (another partition) still works

And the fact is that they do not try to touch or configuration.

Using QasMixer to change the analog output to multichannel fixed the the no sound problem for me. It was set on headphone FP.

I can confirm that using QasMixer to adjust the configuration settings fixes the incorrect default configuration. It looks like Ubuntu configuration ships by default to send audio on this sound card to the front ports (if they exist), rather than the rear ports (that always exist), and then does not provide a clear path to the relevant configuration setting. Installing QasMixer allows easy GUI access to the necessary configuration settings.

This is just my intuition, but it appears to be a bug within the default "Sound" panel under "Settings": the Input tab correctly lists both the back and front panel microphones, but the Output tab only lists the back panel speakers (which actually aren't the back panel speaker jacks, but instead sends the audio to the front panel jack, as revealed by QasMixer). I may be entirely incorrect, perhaps it's a driver issue!

Hope that helps someone? If I knew anything about programming, I'd take things apart and look myself. Since I don't, I figure I'd add as much detail as I could imagine would be useful in order to help someone else get up to speed on the issue. If anyone has any questions or problems, I've subscribed to this bug report and will (eventually) respond to requests for more information.

still not working on ubuntu 16.04

using qasmixer to change "headphone" to "multichannel" fixes it

p.s. you could also use alsamixer - f6 select the xonar - go to tab <analog out> and use up/down to change output...

This bug is still present on Ubuntu Mate 17.04 in 2018 with Xonar DG card. I used the alsamixer technique described above for making the rear panel work.
