ked som mal hardy-ho tak som to riesil podla navodu z http://www.automaticable.com/2008-05-28/how-to-enable-surround-sound-on-ubuntu-hardy/
konkretne (http://automaticable.com/wp-content/uploads/2008/05/ss07-channels.png) a zaciarkol som len center a surround a vsetko bolo vyriesene.
len v karmic je uz volaky iny alsa-mixer a ten nema moznost si zaciarknut center a surround.
teda je nejaka moznost ze by som downgrade-oval alsa-mixer z karmic na hardy ?
