Slices passed to the callback don't provide enough data in stereo mode.
The patch provides a sine.go test running in stereo and a fix for the problem.

Just a quick note - this is a great little project.

Might want to drop a hint in your readme that to get it to compile in Ubuntu 
you need to

`apt-get install portaudio19-dev`

When I run eg. examples/enumerate.go, I get a panic.

Looks like I have two audio devices found by portaudio;

1. OSS
2. ALSA

The first one does not have a input or output device at all. This is version 
19+svn20071022-3.2 of portaudio found on Debian Squeeze.

Using the latest version from SVN only shifts the order of them.

Am I not supposed to have a device like this? Attached is at least a small fix 
to the problem.

To make this work with Go 1 required a lot of changes.

See the attached patch.
