Hi, I'm not very familiar with the Lubuntu system scripts,
but on most Linux computers, running Alsa for the sound
manager, you can store and restore your alsa.conf settings.

Google for "alsactl store " for how to store and restore
your personal settings when you login.

alsctl store will save settings to a file you specify with -f

Then when you logon, use alsacontrol restore to reload
your setting file.
