I was suspecting that much, however this sounds like "who cares about
this 1%" -- I say: "it may or may not be 1%, and they probably care" ;-)
Yes, I understand why users want software mixing if their soundcard
doesn't support hardware mixing. I was there once. I support effort of
getting it working out of the box for them. But I wouldn't like for
Fedora to forget about those who build their machines to have better
support just to discover that a year later their distro takes away
support for their harware (or gives them hard time to get that support
working right again).

Always good to hear :-)

That would be great! And that's what I would expect to happen if
implemented correctly, not less.

I understand that there are some technical difficulties and sometimes
developers need time to figure out how to do "the right thing" in all
possible hardware/software configurations.
That's why I'd be happy if there was clear and documented way of turning
software mixing off if the user wishes. That should also keep it off
after some related packages get upgraded.
Kind regards,
Dariusz
