Phosh quick menu System Volume slider disabled

[Torbuntu]

In the drop down quick menu on Phosh the system volume slider is missing the knob to adjust volume.

This makes it impossible to change volume from Phosh.

@Torbuntu IIRC you have a partial answer to that

This is all I really know. Looks like something to do with gvc, but that is the bulk of where I got with this issue.

I see that the libgnome-volume-control commit on the phosh repo is a few releases behind Fedora.

A few commits ahead of the one they use is this: https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/commit/3f457453f031a2936ff267348107e6513be3aa27 which looks like it added the error I am seeing. This doesn't mean that it created the error, but maybe just exposed it. Still unsure what is missing/broken here.

I updated the libgnome-volume-control to the latest commit on the Phosh repo, which did not solve anything.

more errors when playing with sound in gnome settings:

Jun 26 22:35:03 localhost.localdomain phosh[1034]: g_signal_handlers_disconnect_matched: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

I see in phosh's settings/gvc-channel-bar.c https://source.puri.sm/Librem5/phosh/-/blob/master/src/settings/gvc-channel-bar.c this define:

#define ADJUSTMENT_MAX_NORMAL gvc_mixer_control_get_vol_max_norm(NULL)

Which corelates, at least in name, to this error I see in journalctl -e | grep phosh

Solved by reverting the libgnome-volume-control dependency to the same version used in the phosh repository. Updated the spec file to fix it.

Fixed in phosh-0.3.1-3
