I don't remember what I fixed in quakeforge1 to >get it working, but it was something like the above. sorry, but your fix was incomplete. the problem is not the ioctls, but the mmap() call on -STABLE needs read/write access to the sound-device (don't ask me why). the problem doesn't occur on -CURRENT. see the thread on -multimedia "mmap'ed sound buffer doesn't work in -stable, but works in -current" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
