Other Parts Discussed in Thread: LM386
I'm designing a head mounted display with a sound system
I want to use an audio codec with USB interface, including speaker and microphone,
I chose the PCM2912A as the main structure of my design, but this is for a headphone driver,
So I changed the headphone output section to LM386 to drive two speakers CMS-401305-18SP (8 ohms 1 watt)
and select the ECM microphone, CMC-2742PBJ-A,
The schematic is shown below, is this correct or is there any other circuitry I need to modify/pay attention to?

I'm not sure that the pictures will broken or not, so I used the google drive to upload my design!
Thank you
Best Regard Steve
