To automatically detect the UUID of the USB drive and mount it on insertion, you can modify your script and udev rules to use the UUID instead of relying on device names like /dev/sda1.

Here's an example of how you might approach this in Python:

1. Install the required libraries:

If you haven't already installed pydub, you can install it using pip:

pip install pydub

2. Load and concatenate the alphabet sounds:

Here's a simple example:
