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. Claude Buisson 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..
