All of the CD-playing apps are still failing to work properly. Some slight improvement, in that most of them are now at least recognizing an audio CD in the tray, but they still won't play it. -- Conrad J.

Claude, Thanks for digging into this a bit. I just added some code to make it easier for applications to detect at runtime if ATA_CAM has been configured in the kernel: http://lists.freebsd.org/pipermail/svn-src-stable-9/2011-October/000114.html I am not 100% sure how the CD driver works with ATA_CAM. I think you might need to look at: src/sys/cam/scsi/scsi_cd.c and also read the cd(4) man page. We may need to extend scsi_cd.c, but I'm not sure. -- Craig Rodrigues rodr...@crodrigues.org ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
