# This script toggles video and audio output between two setups:
# 1. monitor with stereo speakers on desk
# 2. TV with 5.1 surround sound
# only one of these screens is enabled at a given time
# It can be mapped to a key combination to be able to switch between the screens without having to turn on the currently active screen only to switch to the other.

# To accomodate for your own setup you would need to change:
# - video output names (determine with `xrandr`)
# - display resolutions, refresh rates
# - audio sink names (determine with `pacmd list-sinks`)

# switch to desktop screen if TV is the primary screen
if xrandr | grep primary | grep "HDMI-0"; then
        # switch to desktop screen
        xrandr --output DP-1 --primary --auto \
               --output HDMI-0 --off
        # wait until the HDMI audio output for the desktop speakers is available
        sleep 7s
        # first switch back from 5.1 surround to stereo profile
        pacmd set-card-profile 0 output:hdmi-stereo-extra2
        # switch audio output to desktop audio
        pacmd set-default-sink "alsa_output.pci-0000_02_00.1.hdmi-stereo-extra2"
else
        # switch to TV screen and force refresh rate (necessary for my TV)
        xrandr --output HDMI-0 --primary --rate "59.94" --mode 1920x1080 \
               --output DP-1 --off
        # wait until the HDMI audio output for the TV is available
        sleep 7s
        # configure audio
        # first try stereo audio output for TV in case surround output is not listed
        pacmd set-default-sink "alsa_output.pci-0000_02_00.1.hdmi-stereo-extra1"
        # now try surround output
        pacmd set-default-sink "alsa_output.pci-0000_02_00.1.hdmi-surround-extra1"
        # switch to 5.1 surround profile
        # see https://www.whatsdoom.com/posts/2015/12/01/configure-pulseaudio-output-via-command-line/
        pacmd set-card-profile 0 output:hdmi-surround-extra1
