In Ubuntu Lucid (10.04) if you try to use Brasero to do a straight 1:1 copy of an audio disc, it will complain of missing ‘cdda2wav’.
cdda2wav is provided by icedax; you can install icedax using Synaptic or the following command:
sudo apt-get install icedax
However, you’ll still get a warning. This time brasero will tell you that something is missing, but it will not say what it is.
This is reported to Launchpad, against brasero, as bug #592626: brasero can’t copy audio cd (useless error message).
If you’re willing and able, I would encourage you to stop by the Launchpad site above and lend a hand towards getting this resolved. If you’re not able to do that, and just want to get things working, I actually suggest using k3b. As long as you don’t mind all the kde dependencies, it’s a great program.
Install k3b using Synaptic, or the command line: sudo apt-get install k3b
UPDATE: According to Launchpad’s bug report, this has been fixed since brasero 2.32.0-0ubuntu2.2. Users who continue to experience an issue should make sure they’ve updated, and then file new bug reports.
