Tried it on two different PCs with |the same result. I can hear the au files perfectly well on my Macintosh |so they are not corrupted or anything like that. | |Is there a way to set the volume or any documentation on this. I have |tried the handbook, faq and the archives without much luck. I'm going to hazard a guess there isn't. As I recall from my old DOS days, the original PC audio hardware was really primitive. It only had a single bit to twiddle for the speaker. 0 = move the cone in; 1 = move the cone out (or vice versa). No control to vary the degree to which the cone is moved in and out. The speaker was/is real tiny anyway, so low frequencies didn't fare well. So you could generate simple tones by adjusting the rate you twiddled this bit, but generating complex harmony or reproducing recorded files was not done originally. [I still remember the first game out there that did the latter (MeanStreets) to play prerecorded files and how cool that was at the time.] 'course, this anemic original design was one of the reason for the success of the original Sound Blasters.
