"Ich (mein Sohn) verwende(t) einen schon in die Jahre gekommenen Sony PCG-GRT 816 M (das Teil hat schon gut 6 Jahre auf dem Buckel!). Umso verwunderlicher, dass es dafr noch einen Treiber fr die Soundkarte gibt!!! Nun denn, vielleicht werde ich ja nun auch noch einen Treiber fr die GeForce Go5600 aufstbern. Ein herzliches Dankeschn an DriverGuide!"
