I have installed Volumio 2 Beta on a raspberry Pi 2 with a Audiophonics isabre ES9023 TCXO DAC. I edited the /boot/config.txt with dtoverlay=hiberry-dac. The Volumio 2 Web ui works well but there is no sound. I have read through several posts on volumlo 2. It is unclear if the i2c driver/module has been implemented in Volumio 2 at this time. Does anybody have any insight into the situation. Any help would be appreciated.
