Title: HDMI out to HDMI monitors: Overscan vs Force-dvi audio (**Reopen 40748**) Status in linux-hwe-6.2 package in Ubuntu: New Status in xorg-server package in Ubuntu: New Bug description: This is essentially a re-open of bug https://bugs.freedesktop.org/show_bug.cgi?id=40748 What's the problem: Given a TV monitor, with an HDMI to HDMI cable, I have two options for this TV. 1. TV mode -- overscan erases the edges of what's displayed. 2. Monitor mode: No overscan (good). As far as I can tell, going into monitor mode requires using DVI mode through xrandr. But, X seems to tie both DVI mode, and "no audio exists" to the same switch. Even to the point that the DVI mode is listed as an audio setting option. Repeat-bys: 1. Full monitor quality display, audio disabled: 173 xrandr --output HDMI-1 --set audio force-dvi 2. Overscan TV quality, audio working: 174 xrandr --output HDMI-1 --set audio on What I want: DVI display with audio still enabled. Note the issue with the old bug (40748): The person had a DVI to HDMI cable, and was unable to send audio over it -- and needed a way to force the X system to treat it as non HDMI and non audio. diff --git a/drivers/gpu/drm/i915/intel_hdmi.c b/drivers/gpu/drm/i915/intel_hdmi index 226ba83..1bb6996 100644 --- a/drivers/gpu/drm/i915/intel_hdmi.c +++ b/drivers/gpu/drm/i915/intel_hdmi.c @@ -335,8 +335,8 @@ intel_hdmi_detect(struct drm_connector *connector, bool forc if (edid) { if (edid->input & DRM_EDID_INPUT_DIGITAL) { status = connector_status_connected; - intel_hdmi->has_hdmi_sink = drm_detect_hdmi_monitor(edid - intel_hdmi->has_audio = drm_detect_monitor_audio(edid); + //intel_hdmi->has_hdmi_sink = drm_detect_hdmi_monitor(ed + //intel_hdmi->has_audio = drm_detect_monitor_audio(edid) } connector->display_info.raw_edid = NULL; kfree(edid); So ... yeah, there are existing issues that need both of these, to treat it as just a DVI connection; and then, mine (a Vizio) needs it to be treated as a DVI **with audio**. In other words, the "audio force-dvi" needs to support separate "display force-dvi" and "audio off". Because, looking over docs online, it really does seem that audio over DVI can happen, and a physical HDMI to HDMI cable can, and it seems this TV/monitor wants the video signal sent as DVI, not as HDMI (which triggers TV overscan.)
