-[[!meta title="Sound Support"]]
-
-The Hurd presently has no sound support. Fixing this, [[!GNU_Savannah_task
-5485]], requires two steps: the first is to port some other kernel's drivers to
-[[GNU_Mach|microkernel/mach/gnumach]] so we can get access to actual sound
-hardware. The second is to implement a userspace server ([[hurd/translator]]),
-that implements an interface on top of the kernel device that can be used by
-applications -- probably OSS or maybe ALSA.
-
-Completing this task requires porting at least one driver (e.g. from Linux) for
-a popular piece of sound hardware, and the basic userspace server. For the
-driver part, previous experience with programming kernel drivers is strongly
-advisable. The userspace part requires some knowledge about programming Hurd
-translators, but shouldn't be too hard.
-
-Once the basic support is working, it's up to the student to use the remaining
-time for porting more drivers, or implementing a more sophisticated userspace
-infrastructure. The latter requires good understanding of the Hurd philosophy,
-to come up with an appropriate design.
-
-Another option would be to evaluate whether a driver that is completely running
-in user-space is feasible. <!-- TODO. Elaborate. -->
-
-Possible mentors: Samuel Thibault (youpi)
-
-Exercise: This project requires kernel (driver framework) hacking as well as
-some Hurd server hacking; so the exercise should involve either of these, or
-even both. You could for example port some newer driver to run in the existing
-framework (see the [[device_driver|driver_glue_code]] project description), or
-try to make some fix(es) to the [unfinished random device
-implementation](http://savannah.gnu.org/patch/?6088) created by Michael
-Casadevall.
