Default soundstream picasso no output

I have a soundstream picasso that has very small output. signal is getting out of the preamp but not getting out of the amplifier stage. it seems that mute circuit is not working right. I don't have a schematic to troubleshoot this unit. Does anybody out there has an schematic I can borrow or have any idea where the problem could be. Any help would be greatly appreciated. there is an I.C in the power supply section HEF40106B HEX INVERTER that i'm not sure what it does.

Thanks in advance
