From aae7e412b0ec0378e392b18c50b612dae09cdb74 Mon Sep 17 00:00:00 2001 From: V sujith kumar Reddy Date: Wed, 23 Nov 2022 17:49:08 +0530 Subject: ASoC: SOF: amd: Fix for reading position updates from stream box. By default the position updates are read from dsp box when streambox size is not defined.if the streambox size is defined to some value then position updates can be read from the streambox.
