 $0.60 for 10pcs on aliexpress... no USB connecttion though

 bear in mind cost-wise it's competing against the CM108AH which is
below $1 and includes the USB PHY, supports SP-DIF and other digital
PCM formats, headphone jack, line-in and out modes, microphone, and
some control/config pins.  16-bit DAC, 16-bit ADC, 44.1khz and 48khz
sampling, and a built-in power regulator so you only need to supply 5V
from USB.
