It appears an HID status register exists but no information in the datasheet that would allow external reading of volume level. Is there a way to read the static volume from a PCM2705 using SPI?

Hi Dale,
No, it is not possible to directly read the internal volume register on the PCM2705 using SPI. The SPI 's functionality is limited to being used to write HID-type commands (volume up, volume down, mute, etc.) to the PCM2705, or for programming the device's descriptor.
