Automatically switching tv layout and sound hardware when connecting HDMI

acid_kewpie · 09-19-2011, 04:57 AM

Howdy,

Does anyone know if there are any shortcuts to automatically enable video and audio through HDMI when I plug my laptop into my AV Receiver?

Currently in Gnome I go into system settings, displays, enable the new 2nd screen and set the resolution and apply. then I go to sound preferences and change the hardware from internal analog duplex to hdmi output.

I'm not that fussed about it all configuring by itself, but I'd really like to be able to script the config changes at least.

Any clues?

since you are a moderator...forgive me for asking but have you considered creating an udev rule?

acid_kewpie · 09-20-2011, 01:32 AM

to do what? I can certainly fire off a bunch of commands when I plug my TV in, but what would those commands actually be? TBH I'm not even sure what controls the sound config these days. I've been "just using" fedora for so long I've paid so little attention to what's under the hood!

sorry I don't use fedora but until you get a better reply try this when you get a chance pls

1) with laptop not plugged into device....consider posting the output of your xorg.conf
then plug in to device......if xorg changes post both before and after files pls.......we can use them to create an udev rule.

2) Not sure why gnome uses for sound....do you have pulseaudio running? or oss or alsa?

You may wish to double post to http://forums.fedoraforum.org/?

sorry I am having trouble with my browser which I have reported.

we will also need the output of

lspci

2) Can you also have a look at where your udev rules are pls

mine are at /etc/udev/rules.d

Pffft! Why is it so so often the case that I can't make any progress until I ask for help then work it out myself anyway???

Code:

#!/bin/sh
if [[ $1 ]]
then
  xrandr --output HDMI1 --off
  pactl set-card-profile 0 output:analog-stereo+input:analog-stereo
else
  xrandr --output HDMI1 --mode 1280x720 --right-of LVDS1
  pactl set-card-profile 0 output:hdmi-stereo+input:analog-stereo
fi

Hurrah. job done. I don't know if it's feasible to make a udev rule for removal as my laptop seems to screw up royally if I try to look at the display layout if the TV is configured but absent. Nice enough start though. Thanks for the mind nudge.

ok I think I found my udev for my sound elsewhere at

/run/udev/data/~soundcard and its contents are

I:5497203
E:SOUND_INITIALIZED=1
E:ID_VENDOR_FROM_DATABASE=Intel Corporation
E:ID_MODEL_FROM_DATABASE=N10/ICH 7 Family High Definition Audio Controller
E:ID_BUS=pci

I'm having the same problem except it only happens with the audio. The video is automatic but i have to go into sound and change it manually when hooked up to hdmi. I don't want to screw anything up so if I use your code and just leave out the video settings will this work or do I have to change any of the values?
