Anyone other than me notice that this guy works for HP? :-)

No. The worm driver doesn't support reading from the device at the
moment at all. I just use lose95 to read the tracks, then byte-flip them
and massage them with sox (sox -x foo.wav foo.cdr works for me) and burn
them under Unix.
Also: Go get the latest flash image for the burner.
% dmesg | grep HP
(ahc0:3:0): "HP C4324/C4325 1.25" type 5 removable SCSI 2
The "1.25" is the ROM rev. 1.25 is the latest I know of.
>Question 2: Can I burn audio-CD's under FreeBSD?
Yes. The driver as of 2.2-9610xx-SNAP has a couple of bugs that prevent
audio from working, but this patch clears it up. Track-at-a-time mode
is all that's supported at the present.
This patch also _removes_ a check that ordinarily prevents making
multi-track yellow book CDs. The old Sun Catalyst CDs used to have
a data track and a couple of audio tracks, so as long as your CD player
skiped the first one, it looked like an ordinary redbook CD. The
computer would only care about the first track, which was yellow.
Everybody won.
