You've probably come here because somebody asked you to provide Alsa information to troubleshoot an audio issue. To begin, open a terminal by pressing Alt+F2 and entering 'bash' (without apostrophes) as the command.

For Ubuntu 12.10 and above, enter this command in the terminal:

  /usr/share/alsa-base/alsa-info.sh

For Ubuntu 12.04 and below, enter these two commands in the terminal:

  cd ~/
  wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

You will be prompted to upload the information or save it locally. The easiest way to share the information is to automatically upload it to the alsa-project server and copy/paste the address you're given. You can also choose to save the information locally, and alsa-info will output a text file in /tmp . You can then upload that file to whoever wants it. (Remember: files in the /tmp directory will be removed on every reboot.)

Thank you for helping!

Note: If you're working with pre-release hardware, where hardware details cannot be made public, make sure you DO NOT upload it to the alsa-project server.
