Keyboard sound is too intermittent and laggy to be useful

Bug Description

Ubuntu Trusty r188, Samsung Galaxy Nexus

1. In System Settings > "Language & Text", turn on "Keyboard sound" if it is not on already.
2. Go to an app where you can type something, and type a sentence.

What happens: The keyboard sound plays less than half the time, and delayed by a second or more, such that it does not give useful confirmation of typing. For example, I just typed "Hello are you there", and the sound played eight times.

What should happen: The sound plays within about 200 ms of every keypress. And if it ever lags, it catches up rather than just dropping plays.

On a Nexus 4 the difference is far less noticeable. When typing really fast I can see that some key presses can not be heard, but it doesn't seem to be problematic - have to check how this looks like on Android. But the delay of key press sound should be anyway fixed indeed.

I've proposed a branch that should improve this, however I only have a Nexus 4 to test with so it'd be useful if someone with a Galaxy Nexus could also test to confirm whether the improvements are adequate.

  * Gradually decreases the interval between word deletion when
    backspace is held down, allowing for fast deletion of large blocks
    of text (fixes bug #1289374). (LP: #1289374)
  * Reduce latency for key press sounds by switching to a SoundEffect
    element (lower latency and better at simultaneous sounds than Audio)
    and triggering the sound on key press rather than on release. (LP:
