I have successfully recorded from my USBDualTubePre microphone preamp using the S/PDIF into my M-Audio 2496. I used mhWaveEdit. The issue was that qjackctl was displaying the Readable Clients/Output Ports and Writable Clients/Input Ports of my _motherboard_ audio, not my M-Audio 2496. A recent off list reply coached me to set the correct device in Qjackctl with "Setup | Interface | >". Early on, Len Ovens informed me that the S/PDIF inputs of the ice1712 are 9 and 10. And of course, using envy24control to set "Master clock" to s/pdif rather than a sample rate was required as well. And so, thank you to all who responded! _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
