Many thanks It works just fine it's just my dazzle that refuse to grab the audio signal from the commodore (works fine for the video) with the sound command I've been able to produce a signal at about 1000hz and verify that it was really controlled by the sound command. (I also compared to the video signal...) The signal I get on my oscilloscope is roughly a square signal, between -0.3v and +0.3v Is it normal for a commodore ?

Can't find my manual at the moment, but this should give you something: VOL 6 SOUND 1,200,2000 (SOUND <channel>,<frequency>,<duration>) Hope this helps Gerrit Message was sent through the cbm-hackers mailing list Message was sent through the cbm-hackers mailing listReceived on 2012-03-14 21:00:09
