This reminds me your note:

    PA does not make use of hardware mixing. And I don't plan to change
    that. It's obsolete technology. CPUs these days come with extensions
    such as MMX or SSE precisely for speeding up DSP tasks such as PCM
    mixing. This is way more flexible that hw mixing, and definitely the
    way to the future, both on the desktop and on embedded envs as well.


The "obsolete technology" -- who made this decision? Is it your private
opinion or any suggestion from sound card manufacturers?

It seems that HW companies still produce the "obsolete technology".
