nejaky navod je na SuSE

Trosku vyhoda nebo nevyhoda je, ze audio vystup je analogovy, ze se cele radio nepripojuje jen pres USB sbernici, ale potrebuje jeste jeden vstup na zvukove karte. Na druhou stranu, jej lze pripojit primo do externiho zesilovace a ovladat jej z PC. Neni potom ale lepsi koupit radio nezavisle na PC??

V mdk90 se mi po velkem boji adapter podarilo rozchodit. Driver sice je, ale je trosku problem s user space aplikacemi, vetsina je neaktualnich a nejdou snadno prelozit. Podarilo se mi prelozit plugin do xmms a gradio. Jinak by mela fungovat kazda aplikace podporujici radio pres v4l api.
