Switch Pulseaudio Sink

This repository includes two tools to switch pulseaudio default output and the output for every application to another sink.

• Documentation (and FAQ – if any) can be found in this README.
• There is currently no package to install the script. You need to download the script you want directly or clone the repository.
• Feel free to file issues to report bugs, ask questions, or request features.
• Feel free to open a pull request. Please use the black code formatter if modifying python code.

pulse-audio-cycle.py

This python script aims to toggle between different outputs by cycling through different cards and profiles (A card plus profile lead to a sink). Cards and profiles can be filtered by providing a regex pattern. It can send a notification via GTK 3, if wanted.

If you do not filter for profile, the profile of the card will just stay the same.

To get a list of all Cards and Profiles:

./pulse-audio-cycle.py -v --dry --use-sink-description --with-unavailable

To get a overview of all options use:

❯ ./pulse-audio-cycle.py --help
usage: pulse-audio-cycle.py [-h] [-n] [-p CARD_REGEX PROFILE_REGEX]
                            [-c CARD_REGEX] [--use-sink-description]
                            [--with-unavailable] [--dry] [-v]

optional arguments:
  -h, --help            show this help message and exit
  -n, --notify          Use this to notify which Sink and Profile was swiched
                        to
  -p CARD_REGEX PROFILE_REGEX, --profile CARD_REGEX PROFILE_REGEX
                        With regex_for_card
                        regex_for_profile_the_card_should_get. Can be
                        provides multiple times – for different card
                        patterns.
  -c CARD_REGEX, --card CARD_REGEX
                        Regex pattern of cards to cylce through. Use in
                        combination with --profile to set profiles during
                        cycle
  --use-sink-description
                        Instead of only looking at card names, also match
                        regex against sink description
  --with-unavailable    Don't skip unavailable profiles (if they match the
                        pattern).
  --dry                 Don't change sinks or profile (Useless without -v)
  -v, --verbose         Print extra details for debugging purposes

Caveat

Unlike switch-audio-sink.sh it does not offer an interactive selection. If anybody needs it, feel to open a PR with a new option for --selection-command 'dmenu' or something of that sort. Currently I do not have a use case for interactivity.

Requirements

• pulsectl
• python 3.6 (Because of format strings)
• GTK 3.0 for notifications

switch-audio-sink.sh

This rough bash script either works interactively to offer a selection of pulseaudio sinks to switch output default to (and all running applications) or toggles by a provided regex. It cannot switch profiles.

It precedes pulse-audio-cycle.py. Since switch-audio-sink.sh offers interactivity which pulse-audio-cycle.py does not, I kept the bash script for now. If the python version ever gets an interactive mode, it will be obsolete and get removed.

Options

• You can toggle by using -t PATTERN
• You can send notification via notify-send with -n
• Show current default output in dmenu with -d

Requirements

• pactl
• dmenu if you use it interactively and not toggle trough options with -t
• notify-send if you use -n

Installing

Just put the script you need in a place you like, e.g. ~/.local/bin/.
