My v90 started to develop a similar problem where the left side speakers were very quiet. After some time I tracked the problem to the volume control on the stereo, and in particular it is linked to the automatic volume control which adjusts the volume in relation to the speed. I stripped the radio and cleaned the switch with maplin switch cleaner. Problem dissapeared for a year or so but returned, so, as it is probably impossible to buy a new control for the radio, I just turn the volume control round and round rapidly until sound returns.
