tpmmld 1.1.3

ThinkPad mute-mic light daemon

tpmmld

tpmmld is the ThinkPad Mute-Mic Light Daemon. If you have a certain ThinkPad where you have a mute-mic indicator led on the F4 button, this daemon will control it, based on the current PulseAudio mute state of all input sources (So all input sources mute, all input sources unmute).

When the daemon runs, it monitors for mute state changes on any input source. If any input source is muted, all input sources are muted by the daemon, likewise with unmuting, if any input source is unmuted, all input sources are unmuted.

Note: to enable/disable the led, the sudo and tee commands are used. I'm sure there's a better way, but I didn't want this program to run with elevated privileges itself. You have to configure sudo in such a way that you can run echo 1 | sudo tee /sys/class/leds/platform\:\:micmute/brightness non-interactively (i.e., without a password prompt).

Install

Ideally:

pip install tpmmld

However, If it's not available there for whatever reason, you can also get it going yourself, directly from the git repository:

git clone https://github.com/rubin55/tpmmld
cd tpmmld
python -m venv .venv
pip instal -r requirements.txt
bin/tpmmld.sh -s # shows available input source devices, with index number
bin/tpmmld.sh    # run tpmmld in foreground
bin/tpmmld.sh -d # run tpmmld in background

Usage

$ bin/tpmmld.sh -h
usage: tpmmld [-h] [-a] [-d] [-i INDEX] [-s] [-l {WARNING,ERROR,INFO,DEBUG}] [-v]

options:
  -h, --help            show this help message and exit
  -d, --daemonize       run in background (daemonized mode). If not specified, the process will run in the
                        foreground output to stdin
  -s, --sources         show list of sources, with index numbers
  -l {WARNING,ERROR,INFO,DEBUG}, --loglevel {WARNING,ERROR,INFO,DEBUG}
                        specify the loglevel to use, defaults to 'INFO'
  -v, --version         show program's version number and exit

Build

Since this is a python package, you don't really need to build, but if you would like to build the pip packages, you can do that as follows:

python -m build

You will then find the pip package binaries in dist/. You can install them using pip.
