Could anyone help me with my problem, that I do not have any sound on V4.0 Beta 1, while sound is fine with V3.3.0? System Volume is always zero and if i raise the volume, it has no effect and is not saved. In recalbox.conf everything looks fine. Even several fresh installs (also including unstable build) did not help. I use a Raspberry Pi 2. So obviously hardware is fine, because everything works in V3.3.0. What is wrong? Obviously no one else had this problem?!
