My A1200 is connected to a 1084S using the standard RGB cable for video and a set of phono leads for sound .
With the phonos plugged in L+R on both ends 80% of the time the sound is coming from 1 speaker with half the sounds missing (as it does) .
Its not the leads (i tried others) , niether the monitor (i tried another too)
When i unplug one plug of the phono leads (not sure which one) from the amiga`s side , the sound works perfectly (no missing music or sounds) but obviosly from 1 speaker only .
Could it be my amiga has something wrong ?
