Audio device switch

[psmbfuer]

I'm new to all of this as well, and only came up with my solution through testing, trial, and error (and of course the starting point that the previous posts provided). I have looked into your question a bit, but I only have one card, so I cannot test through this as I did for my issue.

That said, I started up a pacmd session, than enter "help" (without the quotes). From this you will see an entire list of what is possible and I wonder whether the profile names are identical between your cards, and if not whether you could still use the profile switch that I used above. If not, there is a "set-card-profile" command that would be my next area of research.

Sorry I'm not able to be more helpful.

Here is the code for switching audio INPUTS.

#!/bin/bash
## This code is for switching audio inputs.

declare -i sources=(`pacmd list-sources | sed -n -e 's/\**[[:space:]]index:[[:space:]]\([[:digit:]]\)/\1/p'`)
declare -i sources_count=${#sources[*]}
declare -i active_source_index=`pacmd list-sources | sed -n -e 's/\*[[:space:]]index:[[:space:]]\([[:digit:]]\)/\1/p'`
declare -i next_source_index=${sources[0]}


#find the next source (not always the next index number)
declare -i ord=0
while [ $ord -lt $sources_count ];
do
    echo ${sources[$ord]}
    if [ ${sources[$ord]} -gt $active_source_index ] ; then
        next_source_index=${sources[$ord]}
        break
    fi
    let ord++
done


#change the default source
pacmd "set-default-source ${next_source_index}"


#move all outputs to the new source
for app in $(pacmd list-source-outputs | sed -n -e 's/index:[[:space:]]\([[:digit:]]\)/\1/p');
do
    pacmd "move-source-output $app $next_source_index"
done


#display notification
declare -i ndx=0
pacmd list-sources | sed -n -e 's/device.description[[:space:]]=[[:space:]]"\(.*\)"/\1/p' | while read line;
do
    if [ $(( $ord % $sources_count )) -eq $ndx ] ; then
        notify-send -i notification-audio-volume-high --hint=string:x-canonical-private-synchronous: "Sound input switched to" "$line"
        exit
    fi
    let ndx++
done;

Basically it's the same code as from the original, just using pacmd list-sources (for input devices) instead of pacmd list-sinks (for output devices).

I can't quite figure out how to work with this. The card at index 0 is my ATI graphics card (ugh), which is apparently responsible for sound via HDMI out. The card at index 1 is my actual sound card.

I found this thread very helpful, but for my needs, I just set up this simple script that switches between my monitor+desktop audio and HDMI tv+HDMI audio.
Since I mostly use my TV with XBMC, I included that in the script, and mapped [Super+Enter (keypad)] to run it.
Now everything switches to my TV when I want to watch something, and switches back when I exit XBMC.

#!/bin/bash

if xrandr | grep -q ', current 1440'

	then
		xrandr --output HDMI-0 --mode 1920x1080 --output DVI-0 --off
		xbmc
		pacmd set-default-sink 0

	while pgrep -u root xbmc > /dev/null; do sleep 1; done
		xrandr --output DVI-0 --mode 1440x900 --output HDMI-0 --off
		pacmd set-default-sink 1

	else
		xrandr --output DVI-0 --mode 1440x900 --output HDMI-0 --off
		pacmd set-default-sink 1

fi

Now if I could only get Igor Cesko's COM receiver to work with lirc...
