PCM2706C: master volume control

Volodimir Bondarenko

Part Number: PCM2706C

Hello,

I am designing a custom USB to Audio interface board that will be installed in the embedded system running Linux.

I would like to make sure that the chip I have selected (PCM2706CPJTR) will work with Linux and the audio volume will be controlled from the OS.

The board will not implement any elements of HID.

The board will use only this chip (working as 16 bit DAC ) and an analog power amplifier.

Thanks

Volodimir
