How to address the S/PDIF output ports on a SBLive!

How to address the S/PDIF output ports on a SBLive!

[Gerard Janssen]

Hi,

I am trying to send multiple digital audio streams to different SPDIF
outputs of my soundcard (SBLive! Player 1024, CT4830, Rev. 6). This
soundcard has a 40 pins external audio connector with four SPDIF outputs
indicated as SPDIF#0 - 3. 

When I use the "front" channel in ALSA, this signal is also send to the
SPDIF#0 output. When I use "iec958:AES0=0x4 , AES1 = 0x82 , AES2 = 0x0 ,
AES3 = 0x2",the signal is send to the SPDIF#1 output. Both SPDIF outputs
can be addresses simultaneously with different stereo audio streams.
However, I have not been able to send a signal to the SPDIF#2,3 outputs.

How do I address the SPDIF#2,3 outputs? Is it possible to send more then 2
(preferably four) stereo audio streams to the SPDIF outputs.
I hope somebody can help me to solve this problem.

Thanks in advance,

Gerard Janssen
