  7. # This script upgrades ALSA on Ubuntu and Linux Mint systems from 2.6.24-28 (non)-ubuntu kernels onwards and is not following
  8. # official Ubuntu/Debian package handling rules
  9.  
  10. # This script is not compliant to Ubuntu official .deb package handling. This script overwrites the existing files and modules.
  11. # You won't see any changes on the revisions if you run e.g. synaptics..
  12. # If there are official ALSA updates supplied by Ubuntu repositories or kernel changes, these will overwrite your manual ALSA upgrade -
  13. # you need to re-run this script in this case.
  14. # You can check the Alsa revision by typing "cat /proc/asound/version" or "alsactl --version" or the utils by "aplay --version"
  15. #
  16. # Note: As usual  I'd like to recommend that you make a backup of your drive first. I don't guarantee for anything!
  17. #
  18. # The script compiles all drivers by default.

  22. # You might want to go through the script and try to understand what it is doing. It's not rocket science. It's not a must though.
