I should ask what kind of Which sound card first off. Assuming the system
uses pulse for something before controls is started, Pulse will turn the
audio card up... if it knows which controls do this. So my old Delta 66
has never come up on a new install with sound coming out unless I turn it
up using mudita24, alsa mixer or qasmixer. It may be reasonable to allow
qasmixer to be opened from within controls for this reason.

On first startup, jackd should not be running but pulse should be. Once
controls is used start jack, it should be running on the next boot if it
was running at shutdown.
While my personal opinion, is that the most stable way to run audio is to
always run jack as the backend for pulse, there may be those who's main
focus is graphics, animation or video and would like to have every bit of
cpu possible available for rendering. These people may want just pulse on
their system and probably do want hyperthreading and Boost enabled, both
of which are bad for low latency audio. (USB is bad for low latency audio
as well, but that is what we are generally left with that most of us can
afford) So there need to be choices and sane defaults. In the case of jcak
starting at session start, My feeling is that in most cases the user needs
to set latency and device the first time they run the system anyway (the
default device on my system has no speakers hooked to it as it is only
used for it's MIDI port)
