One driver is for the ES1370 ASIC and the other one for the ES1371 ASIC :-) The main difference between these chips is the codec interface. The latter supports the generic AC97 interface, which means it has to have built in sample rate converters. > and I have sound... kind of.

Also enable CD as a recording source. > What's the difference between /dev/audio and /dev/dsp? The default sample format for /dev/audio is ALAW (or was it ULAW?), which is not supported by the es137* drivers. /dev/dsp's default is linear 8bit. > Why do most command line sound programs want to output > to /dev/audio by default? Maybe inherited from old Sun audio hardware. > Why I'm I not getting any sound from /dev/dsp? maybe because the mixer volume is too low? > Why is the lineout channel (dsp1) so low on volume? Same as above probably > How do I tell the es1370 driver to have the joystick port > ON by default? Joystick might be a bit of a problem currently, you might need to delete the request_region for the joystick ports > How do I use /dev/midi? Nothing seems to work. /dev/midi is possibly not what you want, it is a raw interface to the MIDI UART. If you just want to play midi files, use eg. timidity. Tom
