no luck with virtual multi channel devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
  i tried to start up two RME-Cards (a 9632 and a 96/8) as a
virtual multi channel device.
But no chance... several different Instructions found online, did't work :-(
i created the following .asoundrc-file with the help from:
http://alsa-project.org/main/index.php/Asoundrc

pcm.rme9632 {
         type hw
         card 1}

         type hw
         card 1}
pcm.rme968 {
         type hw
         card 0
}
ctl.rme968 {
         type hw
         card 0
}
ctl.rme_multi {
         type hw
         card 1
}
pcm.rme_multi {
         type multi;
         slaves.a.pcm rme9632;
         slaves.a.channels 16;
         slaves.b.pcm rme968 ;
         slaves.b.channels 8;
