Problems Playing CDs with the SB Live. Using "kscd"

[James Courtier-Dutton]

Hello

I have trouble with playing CDs with the SB Live.
The alsamixer "CD" volume control adjusts the volume and the sound comes 
out the the headphone socket.

I want the sound to come out of the SPDIF socket.

If I play a .WAV file, the sound comes out the the SPDIF socket if I 
toggle "IEC958 Optical Raw" so "MM" appears.

No matter what I try, CD audio only ever comes out of the headphone socket.

Another point: -
I can be playing a DVD is AC3 passthru mode which disables all the 
alsamixer controls, meaning that .WAV files will not play while AC3 
passthru is playing.
Even in this mode, the CD still plays via the headphone socket.

Cheers
James

did you adjust "AC97 Playback Volume"?

hmm, which output do you mean as "headphone socket"?
is it a jack on live drive, or a jack on the CD-ROM, or..?

It's ok, CD is connected to AC97 codec which drives only analog outputs 
and contains analog mixing of inputs and outputs. Assuming you're using 
the standard analog output. SB Live cards with LiveDrive has also 
additional digital output which is driven differently.

All? I don't believe. Only controls associated with S/PDIF should be 
locked. The analog outputs from AC97 should be working properly.
