Can you re-check if you run the same samplerate on the IdeaPad and are not running into some 96kHz multiplexing issue? Not that I think if it I remember that I had dead channels just like you on the same interface when I borrowed it a year ago for a few weeks but on the analogue outputs I think. Not much of help I am afraid... best, P _______________________________________________ Linux-audio-user mailing list -- linux-audio-user@xxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to linux-audio-user-leave@xxxxxxxxxxxxxxxxxxxx
