Thanks. sr.c just doesn't check whether the drive reports audio play
capability or not. It just sets it while ide-cd actually checks for
the capability. The drive is not reporting it while it can so ide-cd
needs blacklist entry for it. Now that idecd has blacklist entry, all
should be fine. Eh... I'm not sure whether we need to update sr to
follow what ide-cd is doing or not.

Thanks.
