Configure your mp3 player to play at a rate lower than 44.1kHz, eg try > mpg123 -2 foo.mp3 > > 3. Configure your mp3 player to use /dev/audio rather than /dev/dsp? And try playing the same file. > mpg123 -a /dev/audio foo.mp3 None of these scenarios work. In each case, the behavior is the same: mpg123 appears to be playing the file, but no sound comes out. Oddly, you can specify a non-existent audio device (like /dev/blah or something), and mpg123 doesn't complain at all. It still appears to be playing the file. From a truss log, I never see it opening /dev/audio. Instead, it's loading a lot of ESD-related stuff. So maybe that's not a good test... Hmm. Okay, I see there's a command called 'playwave'. Running playwave with a 2.5 second wav file, it doesn't appear to run -- it exits (with return code 0) immediately. A truss does show it opening and ioctling /dev/dsp, at least. On the other hand, I can do something like this: 'cat <file> > /dev/audio', and static does come out of the speakers. Same with /dev/dsp. -David.
