Hi, sorry for the late reply, I was very busy the last days. And apologies, I think I was a bit to quick in concluding that running the game at low cycle values solves the problem. Looks like it was pure coincidence. I tested now quite a bit and there is no noticeably difference, the music is always …

Sure. But before I play a game in such an tedious way, I will just turn on my windows machine. You know, I just want to get it to work in OS X. If it is a problem of the driver then everybody running OS X in combination with a sc-55 would have the same problem. If it is a problem of the adaptor I …

Same problem. At last I went down to 500 Cycles. This did not solve the problem completely either, but the …

Okay, I did a little bit of testing the last days and found out the following. 1. In all games the before mentioned problems occurs. 2. The problem is not exclusively dosbox related. I tested the sc-55 with 3 Sierra Games (SQ5, Police Quest 4 and Leisure Suit Larry 6) and one non-Sierra game ( …

The adaptor is supposed to be OS X compatible and it is visible in the audio-midi-setup of OS X. In the dosbox configuration file I set …
