From 3e9582267e3a06bfd9622dbd2304a8cfac977b43 Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Fri, 2 Dec 2022 16:28:28 +0100 Subject: [PATCH] ALSA: hda: Interrupt servicing and BDL setup for compress streams Account for compress streams when receiving and servicing buffer completed interrupts. In case of compress stream enlisting hdac_stream for data transfer, setup BDL entries much like it is the case for PCM streams.
