So you will need to combine those cards into one. There are various way to achieve this. I suppose the appropriate solution here would be to use pcm.multi. see http://jackaudio.org/multiple_devices and http://www.alsa-project.org/main/index.php/Asoundrc#Virtual_multi_channel_devices and HTH, robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
