Hi Sascha, have you tested capture direction on an i.MX27 based board? I have been testing your patches in the place you suggested and playback seems to work fine but I have several problems with capture stream. I found a BUG in the audmux_v1 code and I have fixed it but I am still having problems with capture. The file keeps empty and nothing is recorded. Please could you try the following on an i.MX27 based board? arecord -t raw -c 1 -f S16_LE test.wav Thank you. -- Javier Martin Vista Silicon S.L.
