I am the maintainer of VLC, I have an outstanding PR (ports/162190) on the

I can confirm this issues, but don't know enough about driver access to fix

mplayer and audactiy also display issues running as non-root.
Under 9.0-RC3 r228843, I get these errors on boot with no disc present in

These ports are fairly popular, but the problems may not lie exclusively
with their assumptions about FreeBSD. I am running 10.0 on another machine
specifically to test changes under src/sys/cam.
I am worried that with the actual 9.0-RELEASE on the horizon, users will
find show stopping problems using their disc drives.
Try having users merge r228808 and r228847. If that works, then I
would press re@ produce another RC that fixes this.

PS This is coming from a user that was annoyed by this gap with the
ATA_CAM code.
As the submitter of ports/162190, I would firstly ask:
Is the problem corrected by r228808 and r228847 in 10.0-CURRENT ?
If not merging to 9.0 is useless.
If yes I could test.
There are 3 methods to access audio CDs.
- if your drive is connected to your sound card you can use the drive's
built-in audio support (if present). (used by cdcontrol)
- read raw audio data via the CAM layer. (used by cdparanoia)
- read raw audio data via the cd(4) driver. (used by vlc, libcdio?)
The first two should work. The last one has now been fixed in CURRENT,
but programs using that method also seem to use CDRIOCSETBLOCKSIZE
ioctl that cd doesn't implement. The driver already knows the correct
block size though, so it seems safe to ignore the error. With the
attached patch vlc works for me.
I just made the jump, and applied r228808 and r228847 to my sources (stable/9
dated 11/11/27 = svn r228043), and rebuilt vlc with your patch.
Conclusion: IT WORKS !! and I am currently playing an audio CD as I type this
message.
I will make a followup to ports/162190, and hope that the cam patches will be
MFCed before the release.
Thanks
