Trying with wav is likely not worth your while. Though it would make sure that it is not a flac issue.
I did try brasero audio burning with wav and flac today on the daily live 20091026.2 karmic-desktop-amd64.iso on an extensa 5635Z. Worked fine all three times. So it is definitely not a general problem with brasero on karmic.
If you would try brasero from a current karmic live system that would tell us whether it is a configuration problem with your installed system or some hardware-specific issue.
If you use grub2 as your bootloader (the karmic default now) you could simply boot the live iso via grub2 loopback from the hard disk.
I can give you details if you want to.
