Bug description:
[Impact]
* As the status of the jack-midi and pulseaudio-jack bridges are not
updated correctly from the config file, users have to open
ubuntustudio-controls to set the required status every time they
login/logout/reboot.
* The bug is very annoying for users that need to adjust their jack
settings to cater for different audio software and hardware.
* The statuses read from the config file are a string. When
converting from string to boolean to set the check button status in
the gui, python will always evaluate the boolean as "True" for any
string except "None". Now the strings are parsed with some if/elif
statments to set the correct boolean status for the check button.
[Test Case]
* Run ubuntustudio-controls
* The first time ubuntustudio-controls is run, the 4 tick boxes in
the gui (e.g. "Auto Start Jack at Session Start") should be set to the
recommended defaults for Ubuntu Studio. Change the tick boxes to
something else (e.g. all off).
* Click Apply Audio Settings (saves the settings to a configuration
file).
* Close Ubuntu Studio Controls.
* Restart Ubuntu Studio Controls. The previous settings should be
remembered. Previously to the fix, the recommended defaults were set
(ignoring the settings saved in the configuration file).
[Regression Potential]
* The changes are limited to the ubuntustudio-controls app, and this
package is only ever installed for Ubuntu Studio users, or users that
want to add the Ubuntu Studio settings to their favourite flavour. The
only reverse dependency is the Ubuntu Studio meta-package.
* The changes have been tested in my ppa
(https://launchpad.net/~rosco2/+archive/ubuntu/testing) for Disco with
no apparent regressions.
[Other Info]
* The same changes (uploaded to Eoan) have been backported in our
Ubuntu Studio Backports PPA (https://launchpad.net/~ubuntustudio-
ppa/+archive/ubuntu/backports) and is therefore already in the hands
of many users.
[Original Description]
Several users on the Ubuntu Studio list have reported that they only
want the ALSA Jack Midi bridge to be active sometimes.
When switched off in ubuntustudio-controls it always restarts with it
enabled again which is very inconvenient.
