Run alsamixer (media-sound/alsa-utils). Press F6, select the Xonar and |
20 |
look for a "Stereo Upmix" setting. |

Also, make sure you're using the "Virtuoso" kernel driver |
23 |
(SND_VIRTUOSO), not the C-Media "Oxygen" one (SND_OXYGEN). The Virtuoso |
24 |
driver should provide the correct mixer controls for Xonar cards. |

|
26 |
(The Oxygen driver works too, since the Xonar cards use the Oxygen chip, |
27 |
but it might not provide Xonar-specific mixer controls.) |
