Hello Gerard,
Searching the alsa-user list produces a lot of confusion about using our brilliant RME
digi 96/8 card in a multi-channel configuration. You seem to be the most successful,
although I am not sure I have found the most recent messages regarding the subject.
Q1. Can you enlighten me on the current status of the alsa rme96/8 driver effort. Is
the rme96 driver appropriate at all for multi-channel use?
Q2. How do I communicate to the card that it should use ADAT 8-channel mode?
I have experimented with ecasound. I expect the following command to send a wavfile to
channels 0,1 and (duplicate) 2,3. However, it produces halfspeed audio on the s/pdif
output by interleaving the two. (apparently)
ecasound -b:1024 -r -sr:48000 -a:0,1 -i somefile.wav -a:2,3 -i somefile.wav
-f:16,4,48000 -a:0,1,2,3 -o /dev/dsp
