Linux support and AlsaOut() backend

[PlatinumLucario]

Something I've been thinking about for quite a while, since I'm currently helping with a project. There's a function in NAudio called WasapiOut(), but WASAPI is a Windows-only API.

While I am aware that NAudio itself is cross-platform, what if there was a function called AlsaOut()? That would definitely make it more easier to program sound when targeting Linux distributions, just as it does for WasapiOut().

So instead of WASAPI, it will use the ALSA APIs instead, and support all the ALSA functions.

But what do you think? Is there anything that would also be needed for a AlsaOut() function to be added in? I'd really like to know.
