Thank you. I tried that but on starting a playback it gives me an error that the device is in use and does not playback. Should i be enabling anything else for my .copy function to be invoked and successful playback to happen?

Hi,

Can anyone help me - I need to modify an existing driver such that a new .copy function is invoked. how to make sure that mmap is diabled?

Remove SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_MMAP_VALID

from the struct snd_pcm_hardware.info initialisation.
