At the Vin stage, I have a voltage divider dropping down the voltage from around 3-3.5V to 300-350 mV. (I'm not in front my circuit, but I believe the voltage divider is a 100k (R1) and 10k (R2) connected to the high end of the 10k pot. It's not shown in this schematic, but this is essentially the same idea minus the divider.
At one point, the volume sounded very loud and clear. Now, I'm left with about half that volume. I thought it was the 10k pot, so I changed it out, no difference. When I run my meter on pin 3 to check the voltage at the input, I'm getting a lot of noise and reading no voltage. When I place my fingers on the shell of the 10k pot, I also get a lot of noise.
Can anyone provide me some insight on what may be the problem?
