Sound settings crashing when entering "Input" submenu

[PawelLawrynowicz]

What Happened?

After entering sound settings and entering the "Input" submenu the entire window crashes.
I am unable to enter the sound input setting because of that.

Steps to Reproduce

1. Open "System Settings"
2. Select "Sound"
3. Select "Input"

Expected Behavior

The window should not crash and I should be able to adjust my sound settings from the "System Settings" window.
The workaround is to use pavucontrol or alsamixer.

OS Version

7.x (Horus)

Software Version

Latest release (I have run all updates)

Log Output

EDIT:
Assertion 'name' failed at ../src/pulse/introspect.c:1647, function pa_context_set_source_mute_by_name(). Aborting.

Then reproduce the crash and post the terminal output here.

@PawelLawrynowicz I created a branch to fix a crash. Not sure if it works though. Can you test it please? I'll list the instructions below.

1. Open Terminal from Application Menu
2. Type in Terminal sudo apt install git
3. sudo apt build-dep switchboard-plug-sound
4. git clone https://github.com/elementary/switchboard-plug-sound.git
5. cd switchboard-plug-sound
6. git checkout lenemter/try-fix-crash
7. meson build --prefix=/usr
8. cd build
9. sudo ninja install
10. io.elementary.switchboard

This will download required dependencies and install the development version of the plug. Thank you in advance.

@lenemter I followed your instructions and now it doesn't crash anymore.
I also checked if the settings are working correctly and it looks like everything's in order.
Thank you!
