sam Friday night update

[Willem van der Walt]

Hi all,
I just did another update of sam.
Playback and Capture volume controls are now handled correctly.
Also much more error checking.
Coming and going USB cards should be handled better now.

Regarding the controls:
For now, I focused on getting everything working again as I had to rewrite 
quite a bit of the code.
I am learning about Alsa and its API as I go along, and understood some 
things incorrectly at first.
There are still a lot of mysteries in my mind at the moment.

I will think about the suggestions made regarding the controls and see if 
I can get it closer to what people want.

Some of the suggestions would be quite difficult/time consuming to 
implement, given the way the current code is written.

My short-term goal will remain to get the program robust first.
Please download and update again.
The only file which has to be copied is sam itself.
One can even just run it from the extracted directory with dot slash sam.
FWIW, Willem
