ALSA Sequencer Connection Keeper

aseqkeeper watches for the connecitons on the ALSA sequencer, and it tries to keep them connected.

The two most common situations where this is needed:

  1. is when a device is disconnected, and then connected again
  2. when the system reboots

If the user manually makes an ALSA sequence port connection (aconnect or qjackctl), it notices and stores it into a file. The same if the user manually disconnects the sequencer ports.

But if it is the system because of an exit (in ALSA terms), it keeps this memory of a previous connection. Next time the same device connects (checked by name), aseqkeeper performs the connection for you.

Also if the daemon stops (for example shutdown of the computer), it keeps this file and on next run (system boot) it uses this knowledge to set up again the ports, and check for more connections.

Compiling

cargo build --release

Running

target/release/aseqrunner

Installation

You can directly system install it with:

make install

It will compile aseqkeeper and install a systemd service file to keep it running. It will ask for your passsword to be able to install the files. It will run as the installing user.

It will not enable it by default, so on reboots it will not automatically start. To enable it:

sudo systemctl aseqkeeper

And to run it (will not run at enable, and can be run not enabling it):

sudo service aseqkeeper start
