* We now disable audio down/up sampling when all the constraints have been passed in gUM.

** Update: We need to disable TMMBR due to a regression (video freezing under certain conditions). We're still investigating. Once we have a fix, we'll land it in Fx50 and pref on there. If the fix is safe to uplift to Fx49, we'll do so and then pref TMMBR back on in Fx49. (See {{Bug|1279039}}.) | |||
