I've got a CD32 Rev4.1 board that has bad audio from the RCA & headphone

Very low audio and noisy on the two channels R & L

I've replaced already U38B & U15A with no success

U15A is just behind the PAULA chip U3
U38B is just before RCA & headphone output

Wich component is the sound amplifier ?

Is PAULA dead ?

I don't know what to check, change U31 or U38A & U15B ?

Can someone gives me another diagnostic on this problem ?

Audio schemes attached,

Thanks
