No sound on Kicksecure 17 running on 4.2.0-rc2

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?
