I adjusted my radio volume by using the 3D cockpit knobs for UHF and VHF radio. also I reduced the intercom volume but after a while it was again very high, I looked at the knobs but they were still where I set them, at low volume, So I just touched them (did a left and right click) this fixed it. But after a while it happened again. Its a bug. Knobs remain where we set them but the sim forgets the volume. Touching the knobs the sets the volume back where it should be.
It was observed in KTO compaigne.
I’ve BMS 4.35 with U1 installed.
