Alsaplayer is not that smart in choosing which parameters to use to open 
the soundcard with. So the default might work on one soundcard and not on 
another. You have to see what is failing and tune the parameters by hand 
(there are command line parameters to do that). When you use jack it is 
much simpler because alsaplyer does not have any choice, just uses what 
jack was started with.

I don't know of any and I don't think you'll find one. They reflect the 
structure of the alsa mixer and that in turn reflects what the hardware 
can do. Soundcard hardware usually does not have support for "hardare vu 
meter" monitoring... the ice1712 chipset is one that does and you have 
envy24control for it.
