There are three wm8960 codecs in my paltform. I want to test playing music of these three cards at the same time.
But I do not know how to realize this idea by alsa tool aplay. Can someone give me some hints?
Best regards,
Yuejuan

How many DMA controllers (PCM devices) are there? Show the output of "aplay -l".
Regards,
Clemens
