Cannot load/save settings

Envy24control.
Version: 1.0.3+svn13-6 (bionic)
Section: Multimedia(universe)
Ubuntu version: 18.04 LTS

Issue present from at least 16.04,

Whilst envy24control creates and maintains ~/.envy24control/profiles.conf mudita24 fails to do so. This is the case even when the profiles.conf file is explicitly pointed to using the -f option.

In order to capture stdout/stderr messages, I start mudita24 from the command line, thus:

$ mudita24 -c 1 -f /home/fawkes/.envy24control/profiles.conf

On the profiles tab, I can see the named "Card-1" profile previously created using envy24control. Should I click to load the settings from this, the following output is displayed in the terminal window:

Cannot find program '0'.
You must specify path for '0'
Cannot restore settings for card '1' in profile '2'
Use current settings.

Likewise should I adjust settings and click "Save active profile", the following is displayed in the terminal:

Cannot find program '0'.
You must specify path for '0'.
Cannot store profile '2' for card '1'

This behaviour is consistent, regardless of the value of the -f parameter. Setting ALSACTL_PROG to explicitly point to the installed alsactl also has no impact.

As a result of this issue, mudita24 only serves as a control for the currently loaded profile. It cannot be used to create or manage saved profiles.
