audio (acdt01) dump broken? (BETA4 (5))

Hello,

tonight I wanted to consolidate (for an upcoming trekstor i.beat organix) 
my oggs and therefore eval the difference between reencoded 
ogg_at_320vbr->ogg_at_112 and the original reread wavs(tracks)->ogg_at_112vbr.
Unfortunately I couldn't grab my CDs anymore. I can remember I had used 'dd 
if=/dev/acd0txx of=/tmp/track.xx bs=2352' but this doesn't work anymore. I 
can't replay the bits and with oggenc I get:
ERROR: Input file "track15.wav" is not a supported format

_But_:

cdda2wav -D2,0,0 -t 15 -Owav is working fine!
Result is:

[...*SNIP*]
recording 217.8666 seconds stereo with 16 bits _at_ 44100.0 Hz ->'audio'...
percent_done:
100%  track 15 recorded successfully

What am I missing?

Thanks in advance,
