This time I take an alternate route. Lets see if I can start jack even
without PA.
1: pasuspender qjackctl
2: Press "start" on the qjackctl ui.
3: Success.
However, now my system is back to 2005 control status. This might be
fine for some users but not for me as now I can't use skype and any apps
that are not jack aware without running the oss->jack or alsa->jack
wrappers.
Still, if the startup command for the qjackctl icon in the
"Applications->Sound & Video" menu had "pasuspender" infront of it out
of the box I would probably be happy as a normal user until I had to get
access to skype or some other non jack aware app. A relatively small
price to pay.
System load is stable at less than 10%. No sign of hald or dbus
implementation bugs here.
Winner Jack. Pulse audio gets high points for allowing Jack to take
control of the system.
Ding, Ding, Ding. Prepare for round 4.
