Software? No. Electronically clamped. Something outside VIDC pulling the signal. For example if the OpAmp had died and was pulling its input low.Clamped by ? Is this a software configuration ?
Do you really mean Desktop, or just when "RISC OS" has appeared?... when the sound system has been initialised and audio DMA's happening. Because that's what I'd expect. I don't have a RiscPC in a position where I can verify this myself just now though.No I don't see any change in Ws, either in 16bit or 8bit modes, it's a 20KHz 5v square wave all the time (doesn't seem to change when I try the button to make the beep). On power on it's 5v, then when the Desktop has initialised, it's 20KHz.
