Hi fellow gentoo'ers,
I'm running XFCE with pulseaudio.
Hardware is Asus Xonar STX II with the 7.1 daughterboard
Analog Surround 5.1 is selected in xfce4-volumed-pulse.
If I do speaker-test -c 6 all is right. Front audio is put through the
front speakers.
But if I play sound in Firefox and/or Chromium (eg. youtube) the sound
is mainly coming through the rear speakers.
Any advice? If you need more info please let me know, thanks!
Run alsamixer (media-sound/alsa-utils). Press F6, select the Xonar and
look for a "Stereo Upmix" setting.
Also, make sure you're using the "Virtuoso" kernel driver
(SND_VIRTUOSO), not the C-Media "Oxygen" one (SND_OXYGEN). The Virtuoso
driver should provide the correct mixer controls for Xonar cards.
(The Oxygen driver works too, since the Xonar cards use the Oxygen chip,
but it might not provide Xonar-specific mixer controls.)
