>Stereo Audio Codec with Stereo Audio Amplifier uses ES8311 'Low Power Mono Audio CODEC' http://www.everest-semi.com/pdf/ES8311%20PB.pdf http://www.everest-semi.com/pdf/ES8311%20PB.pdf, Mono DAC with differential output. I dont even understand why someone would do that, yes its a $.3 part but real stereo codec from TI (TLV320AIC320x) is just $.6 Edit: looking at BOM it might be caused by Made in China 2025 and trying to get as close to 100% domestic part list for some subsidies.
