The process I used is this. I'll also attach an abbreviated log of the output.
1. Make sure you have an audio cd installed. The command cd-info will verify
you this (just so there's no confusion here). It will also give you track start
information. That is:
cd-info -A --no-device-info
You should get output like this:
Disc mode is listed as: CD-DA
CD-ROM Track List (1 - 22)
#: MSF LSN Type Green? Copy? Channels Premphasis?
1: 00:02:00 000000 audio false no 2 no
2: 02:28:45 010995 audio false no 2 no
2. Run cd-read to dump a small bit of audio info. I usually choose track 2.
cd-read --mode=audio --start=10995 --number=1
You'll see output something like this:
0x0000: eeff 78ff eeff 74ff f4ff 74ff f0ff 76ff ..x...t...t...v.
0x0010: efff 72ff f0ff 74ff e9ff 78ff e8ff 73ff ..r...t...x...s.
0x0020: e8ff 75ff eaff 74ff ebff 74ff f0ff 74ff ..u...t...t...t.
0x0030: efff 72ff e9ff 72ff ebff 72ff e3ff 72ff ..r...r...r...r.
Eject the audio CD. Let's say the above was on a Solaris box where things
aren't working. So now run it on a computer where things are working. In my
situation this is what I get from GNU/Linux.
Here's the corresponding output:
0x0000: 2100 b4ff 1f00 b3ff 1e00 b1ff 1f00 b2ff !...............
0x0120: eeff 78ff eeff 74ff f4ff 74ff f0ff 76ff ..x...t...t...v.
0x0130: efff 72ff f0ff 74ff e9ff 78ff e8ff 73ff ..r...t...x...s.
0x0140: e8ff 75ff eaff 74ff ebff 74ff f0ff 74ff ..u...t...t...t.
0x0150: efff 72ff e9ff 72ff ebff 72ff e3ff 72ff ..r...r...r...r.
0x0160: e7ff 6fff e2ff 6cff dbff 69ff deff 65ff ..o...l...i...e.
0x0170: e2ff 69ff dcff 68ff dcff 6eff dbff 6bff ..i...h...n...k.
0x0180: d7ff 6bff daff 69ff d5ff 6bff d9ff 6eff ..k...i...k...n.
0x0190: d6ff 71ff d3ff 6eff d6ff 72ff d5ff 72ff ..q...n...r...r.
Note that on GNU/Linux things have been shifted by 0x120. But the important
part is that the data is the same: 72ff f0ff remands that rather than ff72 fff0
