I finally bought an audio card to provide digital i/o to my other equipment.
Thanks to advice last year from subscribers to this list, I managed to get an
RME Digi9652 card on the used market within my budget.
Now to the configuration. I am looking for a working .asoundrc file for this
card. The closest I could find was in a Linux Journal article discussing the
Hammerfall HDSP cards, which are not the same as the Digi9652. I adapted the
configuration found in the article somewhat, but wasn't able to produce
output. The kernel module is loaded and identifies the card:
0000:00:0c.0 Multimedia audio controller: Xilinx Corporation RME Digi9652
(Hammerfall) (rev 03)
and I have been able to modify the amixer settings (these are appended to this
message for reference).
My attempt at an .asoundrc file is as follows. I don't understand what the
ttable values mean and couldn't find an explanation on the alsa.org site or
elsewhere.
pcm.rme9652 {
type hw
card 1
}
lct.rme9652 {
type hw
card 1
}
pcm.adat1 {
type plug
ttable.0.0 1
ttable.1.1 1
ttable.2.2 1
ttable.3.3 1
ttable.4.4 1
ttable.5.5 1
ttable.6.6 1
ttable.7.7 1
slave.pcm rme9652
}
Note: for testing purposes this is only supposed to cover the first ADAT
interface.
aplay -D adat1
runs without error.
One possible cause of trouble is a hardware conflict I know to exist with an
EEPro 100 network card on my system which doesn't work now that the RME
Digi9652 is installed. I am working on this.
Configuration experiences/suggestions and any .asoundrc file from a working
system would be much appreciated.
Jason.
