Posting this as RFC because I can't verify this actually fixes the regression as I don't have a ZynqMP. So Rahul, could you test if this fixes the issue and report back?I tested this patch on my ZynqMP platform.
Can you help reproduce the issue at our end. How does your setup looks like? Is it dependent on PL design ? Unless there is some dependency I can try and triage it.
Unfortunately, the issue still persists. Cyclic playback fails after the first buffer period. Regards, Rahul Navale
