Switch outputs pulseaudio in Arch
I wrote this trying to automate switching to my bluetooth headset when I activate it. It works one way, changing to the onboard analog sound sink when no bluetooth is connected. Doesn't change inputs to the bluetooth sinks though. I'm at a loss as to what I'm doing wrong. I had this working fine a couple weeks ago. What is wrong with this script.
Code:
#!/bin/bash
#Tadaen Sylvermane
#mybluetooth
##### variables #####
## sink names
# onboard analog sink name
ANALOG=alsa_output.pci-0000_00_1b.0.analog-stereo
# miisport bt headset sink name
HEADSET=bluez_sink.50_19_09_00_C9_3D
# jbl charge bt speaker sink name
SPEAKER=bluez_sink.00_1D_DF_EE_00_81
## sink indexes
# active sink index
ACTIVESINK=$(pacmd list-sinks | grep index | grep "*" | awk '{print $3}')
# analog sink index
if pacmd list-sinks | grep -B 1 -i "$ANALOG" | grep index | grep "*" ; then
ANALOGOB=$(pacmd list-sinks | grep -B 1 -i "$ANALOG" | grep index | awk '{print $3}')
else
ANALOGOB=$(pacmd list-sinks | grep -B 1 -i "$ANALOG" | grep index | awk '{print $2}')
fi
# bt headset sink index
if pacmd list-sinks | grep -B 1 -i "$HEADSET" | grep index | grep "*" ; then
HEADSETSINK=$(pacmd list-sinks | grep -B 1 -i "$HEADSET" | grep index | awk '{print $3}')
else
HEADSETSINK=$(pacmd list-sinks | grep -B 1 -i "$HEADSET" | grep index | awk '{print $2}')
fi
# bt speaker sink index
if pacmd list-sinks | grep -B 1 -i "$SPEAKER" | grep index | grep "*" ; then
SPEAKERSINK=$(pacmd list-sinks | grep -B 1 -i "$SPEAKER" | grep index | awk '{print $3}')
else
SPEAKERSINK=$(pacmd list-sinks | grep -B 1 -i "$SPEAKER" | grep index | awk '{print $2}')
fi
## current sink inputs
SINKINPUTS=$(pacmd list-sink-inputs | grep index | awk '{print $2}')
##### begin script #####
btpowerup() { # enable bluetooth on login - set to run on startup
echo -e "power on\nexit\n" | bluetoothctl

for input in $SINKINPUTS
do
pacmd move-sink-input "$input" "$1"

}
