Hi!
After i upgraded to buster two weeks ago, sound mixer applet stopped saving/reading its settings, so every time i boot my pc i am presented with "Select Mixer" and have to set channels again. There is kmix_panelapplet_0evyw8vqwb0hupdm6thw_rc in ~/.trinity/share/config with the timestamp of update and simingly correct values, but its not read or something?
