I tested the audio driver with aplay and then suspended to ram (using echo mem > /sys/power/state). After pressing wake to resume, the audio does not play unless aplay is closed and re-run. Do we expect the audio suspend/resume to work? In the platform trigger part I am doing nothing and in case of cpu(i2s) , just disabling the i2s. Best Regards Rajeev
