[linux-audio-user] Reading/playing a "copy protected" CD : cdparanoia seems not to help

[Sampo Savolainen]

Hello,

Do the clicks appear random or do they come at a set interval (i.e. 30
seconds apart) or are they connected to the music (i.e. a crash cymbal)?

Just to be sure, have you tried the CD on a normal CD player? Do you
hear the clicks then? If not, then you could try to find a CD player
with spdif output and, presuming you have spdif input on your computer,
record the data digitally from a normal player.
