It's quite hypocritical of you to use an "anti-open-source" company
(Creative) as an argument for not supporting hw mixing on one side
and then touting other "anti-open-source" companies as examples to
follow on the other.

But whatever. Just please stop imposing pulseaudio on those who don't
want to use it. For the record, I'm still considering leaving Fedora
because - as a GNOME desktop - it's becoming unusable without pulseaudio.
Making it a hard dependency for GNOME bluetooth stack in F11 went a bit
too far in my opinion.
