Thanks.
I can't see how that code works. It looks like only the upper bits of the D/A register are being stored the ADCH. I can't see where ADCL is being used.

This however doesn't explain why your silence is wrong. It should be in the mid range. If not you have lost the negative half of the cycle and you can never recover that.
In addition the large deviation for two samples every four. It should not do that.
