Volume variation in voiceover on Mavericks
When do you notice this problem? Is it when media plays, right after you wake up the computer, when it is doing a lot… That kind of thing. I have never seen this on Mavericks, but if you can offer times when you can reproduce it, I can try to do the same.
As to the second problem, can you explain more in-depth? Again, steps to reproduce are also helpful.
When you say "chokes", do you mean it stutters or sounds broken up? That happens to me every once in a while, usually as or just after a webpage loads. I blame Safari, but I have nothing to base that on - it could as easily be VoiceOver.
Let me know how the ducking thing works. Again, I've never once seen that happen. Do you have the latest updates? Often, stores don't update their machines for a while. Open the App Store and check for updates (cmd-5). install any you find, especially OSX or firmware ones.
I have no issues when it comes to volume and voice over. it remain the same and nevr duds.. The music ducks and tha'ts what I want.
