From 216116eae43963c662eb84729507bad95214ca6b Mon Sep 17 00:00:00 2001 From: Mohan Kumar Date: Tue, 25 Aug 2020 10:54:14 +0530 Subject: ALSA: hda: Fix 2 channel swapping for Tegra The Tegra HDA codec HW implementation has an issue related to not swapping the 2 channel Audio Sample Packet(ASP) channel mapping. Whatever the FL and FR mapping specified the left channel always comes out of left speaker and right channel on right speaker. So add condition to disallow the swapping of FL,FR during the playback.
