Why not use the STM32F072 for audio on the laptop?
not good enough dynamic range and quality, and it is still necessary to have a amplifier. i tried doing audio on an STM32F103RBT6 - i learned that it would not be enough. i *almost* managed it though.
http://www.henryaudio.com/ - the components used in this device would be my inspiration when it comes to audio quality

$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.
