-96dB must be quiet enough to be almost silent. I can't imagine when you would need total silence - turn it off.

My PGA2311 kit from E-Bay has been problematic from the start. For a start it came with no instructions other than "Insert the components as per the silk screen". I did, only to find that the PSU diodes were the wrong way round. It still doesn't work properly. It starts up OK and drops to -96dB. Then it rises to -46dB. From there I can only reduce the volume and not increase it.

the ebay controller code tends to be utter crap.

if you want, you can download my arduino source code and adapt the pga engine board to use an arduino (mine is LCDuino) controller. there is a lot more features in my code and you can change the code, too, unlike the ebay/china stuff.

' you need to modify the board a bit for this code see China_8515_sch_EDIT_THIS.PNG

Here is the code for China board using Atmega8515 fuse INT 8Mhz
download Zip file and edit PCB like in SCH

I removed the 4 sil pullups resistor network
and cut the wire at PIN 9 RESET 89C51 use reverse rest so you need to CUT here

No mine is as per your diagram. Supplied by the same Chinese supplier. I just assumed it was a PIC.
