After upgrading to 4.2 I decided to dis upgrade also my kicksecure templates. Everything was upgraded and seems to work fine. But there is no sound. On Whonix 17 sound works.
Did you use in-place upgrade tool (4.1 → 4.2), or did you do a clean 4.2 install?
In-place tool. After that I also used In-place tool for Kicksecure (16 → 17).
Later I just morph freshly installed debian-12 template to kicksecure-17 and sound works. Where I should report issue for kicksecure in-place dist upgrader?
