I am using what came with SW7.1 cdrtools, which appears to be 1.9.2.
SW8.1 seems to have 1.11a24.  I did not find source code for a later 
version (or a cdda2wav home page).  What libc is your version compiled 
for?

Sounds like any other evolutionary race.  So that is why we are advised to 
get recent versions of cdrtools.

We don't lack a cable, it was just not playing through it one day.
Would you like me to send you a cable?  We have extras.  You can plug your 
speakers in through the jack in front of most CD drives.

This happens even when I tell it to just record the last track.


I was going to ask why a Windows music CD copier (Nero) worked when the 
linux cdda2wav did not - Nero must also have bypassed the copy protection.
Are there newer CDs that the newer cdda2wav still cannot handle?
