I have installed Lucid on an old Mac PowerPC G4 desktop with a M-Audio Audiophile 24/96 soundcard. The only inputs
and outputs I can select in the audio preferences are digital ones for the digital input
and output.
"lspci -v" shows the card as so:

IEC958 (S/PDIF) Digital Audio Output
I believe it is a problem with detecting the analogue input/output. Sometimes I can get sound from the device but it is a sheet of white noise
and tinkering makes it go away again I don't know if that is a separate problem or if it is linked to not being able to see the analogue input/outputs in the sound preferences. Any help would be greatly appreciated
As for the white noise I have installed the Envy24 control panel
and spend lots of time playing with the settings but when I can get the white noise I can never get it to an quality where I can actually hear what is being played.
The internal speaker plays audio fine
and plugging in a NI Audio 4DJ via usb also plays sound, although with some static but I believe that is due to an underpowered usb2 pci expansion card not being able to get enough electricity to the device. Alternatively I have seen other people with problems with this device so it may be a bug in the driver but that is another matter. I would like to get the M-Audio card working so I can begin to enjoy my music once again.
As a note, I do not currently have any audio equipment capable of sending or receiving audio via the digital inputs
and output so I can not check if they are working. The sound preferences show a wide range of digital in
and out options with various surround sound options but no analogue ins
and outs.
