From b1d7e4b41fd0f72ea8149056778db5d737739305 Mon Sep 17 00:00:00 2001 From: Wu Fengguang Date: Tue, 14 Feb 2012 11:45:36 +0800 Subject: drm/i915: add a "force-dvi" HDMI audio mode When HDMI-DVI converter is used, it's not only necessary to turn off audio, but also to disable HDMI_MODE_SELECT and video infoframe. Since the DVI mode is mainly tied to audio functionality from end user POV, add a new "force-dvi" audio mode: xrandr --output HDMI1 --set audio force-dvi Note that most users won't need to set this and happily rely on the EDID based DVI auto detection.
