Hi, did this one slip past? I have not see any response. Alan.
I replied to the original e-mail. Usually, it's better to continue in a thread

Subject: [PATCH] pcm_rate: fix hw_ptr boundary wrapping issue
Date: Thu, 5 Jan 2023 15:35:46 +0000

Wrap the hw_ptr using the total position of the slave hw_ptr, including
boundary wraps. Otherwise, small errors can creep in due to residuals
(when boundary is not a multiple of period size) and which can
accumulate.

Fixes: 7570e5d7 ("pcm: rate: fix the hw_ptr update until the boundary
available")
