>Originator: Masahiko KIMOTO
>Release: FreeBSD 4.1-RELEASE i386
>Organization:
Tokyo Institute of Technology
>Environment:
FreeBSD 3.x, 4.x and current.
Linux Emulation base-6.1.
Any SoundCards, Any Sound drivers.
>Description:
RealProducer doesn't work on linux emulation on any version of FreeBSD
because of lack of a ioctl for /dev/mixer which is used by RealProducer.
>How-To-Repeat:
Install RealProducer, enable linux emulation and run realproducer.
It terminates with error message of 'ioctl is not implemented'
>Fix:
Simply add the conversion of the ioctl to linux emulation module.
The following patch for FreeBSD 4.1-RELEASE solves the problem.
Please apply it to current.
