32-bit acorn hardware • Archimedes 410 Sound ?

Hallo,

I have an Archimedes 410 with 8mb and ARM3 and Beebug VIDC Enhancer which unfortunately has a sound problem.
the small speaker hums or makes strange noises the same happens with headphones.

What have I done so far?
Enhancer deactivated and de-energised and of course set jumper for the Vidc, starts properly but sound problem remains.
Checked power supply, values OK, still installed one from 310, still same error.
Jumper checked seems to be OK as far as I can tell.

Capacitors look good, now I don't know what to do.
Does anyone know the problem or does anyone have a solution?

Thanks
Thomas
