Yep, it sucks.  The impossibility of making in-kernel OSS emulation with
the advanced features of ALSA is probably the #1 unresolved sound issue
afflicting the Linux desktop.  The only solution I see is to get these
apps fixed.  Skype and Macromedia (flash plugin) have been promising
native ALSA support for some time now - maybe that will happen
someday ;-).  We should try to educate closed source vendors that OSS is
not a reasonable option.

You could help by trying to figure out why these apps won't work with
aoss - there are a few open ALSA bug reports with lots of info already.

I don't think anyone has designed a new hardware mixing device in years.
It's all single-access with software mixing these days because it makes
the hardware cheaper.  The Envy stuff will never support hardware mixing
because it works on Windows without it ;-)
