From 8903376dc69949199301b290cc22dc64ae5d8a6d Mon Sep 17 00:00:00 2001 From: Kai-Heng Feng Date: Wed, 18 Aug 2021 22:41:18 +0800 Subject: [PATCH 1/2] ALSA: hda/realtek: Limit mic boost on HP ProBook 445 G8 The mic has lots of noises if mic boost is enabled. So disable mic boost to get crystal clear audio capture.

However, I forgot that the dma_addr field is still not set up for the CONTINUOUS buffer type (that this driver uses) yet in 5.14 and earlier kernels, and it resulted in garbage I/O. The problem will be fixed in 5.15, but we need to address it quickly for now. The fix is to deduce the address again from the DMA pointer with virt_to_phys(), but from the right one, substream->runtime->dma_area.
