My guess is that 4.1.0 kernel module became heavier on CPU and this
impacts sound. I keep seeing this. This is probably general vbox bug,
not FreeBSD port one.
Could you also publish port directory for 4.1.0 virtualbox-ose?
I ran Android-2.2. It runs ok, but no sound. The reason is that VBox
only has OSS option enabled (probably because your build has
--disable-pulse) and Android only supports ALSA and PulseAudio (through
patch).

The ports are available in a tar.gz archive and you find the link to it in the cft mail at the bottom.
I have also seen some audio jitter with Windows guests and 4.0.x but only with the default audio implementation. The problem was gone by switching to Intel HDA.
