This has been discussed before. Hardware mixing is obsolete
technology. Mixing audio on the CPU is cheap and usually done with
better and more reliable quality. Unless someone contributes a patch
PA will not support hw mixing. I am certainly not working on a feture
like that.

As soon as we have revoke() in the kernel the processes of inactive
sessions will kicked from the devices as soon as they become inactive.
