Any change to make it work like the Gne 6 wtithut > I can check specifics next week if you still can't get it working. Still no able to get it working with SOF just like how the P1 Gen does ... > Mark _______________________________________________ Alsa-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/alsa-user
