Just to be sure, I just made the test, and the answer is: NO

I have already written that vlc writes a susccession of messages

[0x2caf2a3c] cdda access error: Could not set block size
[0x2caf2a3c] cdda access error: cannot read sector nnnnn

incrementing each time the sector number.

So I infer that vlc cannot set the correct (audio specific) sector size for the
cam device.

Thanks for your attention.

P.S. As I can see reading GENERIC, ATA_CAM will be the default for 9.X so there
is a risk of complaints from FreeBSD workstation users (who cares ?) after the
release..
