When the hardware can only deal with a monotonically increasing appl_ptr, this flag can be set. In case the application requests a rewind, snd_pcm_rewind() will not return an error code but signal that the appl_ptr was not modified.
This modification itself is fine, but I guess that application may still move the appl_ptr directly via SNDRV_PCM_IOCTL_SYNC_PTR ioctl. We need to verify the backward move there, I suppose?
thanks,
