From 130bce3afbbbbe585cba8604f2124c28e8d86fb0 Mon Sep 17 00:00:00 2001 From: Rander Wang Date: Mon, 30 Sep 2019 09:29:45 -0500 Subject: ALSA: hdac: clear link output stream mapping Fix potential DMA hang upon starting playback on devices in HDA mode on Intel platforms (Gemini Lake/Whiskey Lake/Comet Lake/Ice Lake). It doesn't affect platforms before Gemini Lake or any Intel device in non-HDA mode. The reset value for the LOSDIV register is all output streams valid. Clear this register to invalidate non-existent streams when the bus is powered up.
