Is it 16-bit or 8-bit, stereo or mono, linear, mu-law or A-law encoded, and if it's 16-bit, is it big-endian or little-endian? When you open /dev/audio, the driver sets it to 8kHz, mono, mu-law encoded. It's possible that the mu-law decoding is stuffed, I've never used it myself. I just tried catting a .au file to /dev/audio and it worked fine, though. > Also, if I send a sound to /dev/audio, it plays through both internal and > external speakers.

You can use one of the many mixer programs to set the volume levels for the internal speaker and the headphone output. Paul. [[ This message was sent via the linuxppc-dev mailing list.
