# This script toggles between stereo and surround output.
# It is useful e.g. if you your AVR only provides matrix-decoding of surround
# sound for stereo sources.
# The sink name might need to be changed based on what `pacmd stat` lists as
# the default sink for the desired output device in stereo and surround
# configuration

# use `pacmd list-cards"to determine correct values
CARD_INDEX=0
STEREO_PROFILE_NAME=output:hdmi-stereo-extra1
SURROUND_PROFILE_NAME=output:hdmi-surround-extra1

# use `pacmd stat | grep "Default sink name:"` to determine correct values for
# each configuration
STEREO_SINK_NAME=alsa_output.pci-0000_02_00.1.hdmi-stereo-extra1
SURROUND_SINK_NAME=alsa_output.pci-0000_02_00.1.hdmi-surround-extra1


# switch from stereo to surround
if (pacmd stat | grep "Default sink name: $STEREO_SINK_NAME") > /dev/null ; then
  pacmd set-card-profile "$CARD_INDEX" "$SURROUND_PROFILE_NAME"
  pacmd set-default-sink "$SURROUND_SINK_NAME"

# switch from surround to stereo
elif (pacmd stat | grep "Default sink name: $SURROUND_SINK_NAME") > /dev/null ; then
  pacmd set-card-profile "$CARD_INDEX" "$STEREO_PROFILE_NAME"
  pacmd set-default-sink "$STEREO_SINK_NAME"
