Need to test mixer app using new Pulse and 4a architecture

Close for EE RC5

Works in latest build

Can't reproduce this issue, wait for more explanation.

I do not see that error (on Intel) on master.

If you configure the HAL correctly see my emails in the mailing list with 4a tricks, it does work.

Please note that w have a HAL conflict between Intel Minnow and Intel PC which is not yet solved and needs a Manuel renaming of the unsused HAL. see #SPEC-1190

Below is a captured stack trace on loading the Mixer application. As you can see it failing in an assert in alsa-lib
