We discovered /dev/audio on the Personal Iris and started playing with it. (Thanks to all who sent demo programs!) Unfortunately there is one problem that makes using it a pain: there is a lot of noise (static?) in the output, and probably also in the input. I believe that the noise is transmitted via the power supply from the CPU, since there are obvious correlations between the kind of noise you hear and what the machine is doing, especially bitblt operations such as moving windows are clearly recognizable. It's not just one unit, all the machines we tried have this. It's not impedance either, we are using an 8 ohm speaker as advised. Any hardware hacker know what to do? Or is /dev/audio only useful in the glossy folder? --Guido -- Guido van Rossum, Centre for Mathematics and Computer Science (CWI), Amsterdam guido@cwi.nl or ..!hp4nl!cwi.nl!guido or guido%cwi.nl@uunet.uu.net "Life's gotta be more than meeting pretty faces and sitting on them"
