Thanks for testing ! I was just doing the same test, it works with aplay -Dplug:default good_music.wav
but there's a violent hang (kernel stops, no trace) when I try the record : arecord -v -V stereo -Dplug:default -f cd -t wav -c 2 /tmp/toto.wav last thing I see is : dma dma0chan3: atc_control (3)
I'll try to trace that.
Best regards, Richard.
