+Subject: ALSA: hda/hdmi: Add quirk for TUXEDO IBS14G6
+
+From: Aaron Erhardt <aer@tuxedocomputers.com>
+
+commit d649c58bcad8fb9b749e3837136a201632fa109d upstream.
+
+Depending on the timing during boot, the BIOS might report wrong pin
+capabilities, which can lead to HDMI audio being disabled. Therefore,
+force HDMI audio connection on TUXEDO InfinityBook S 14 Gen6.
