Hi… I was very excited to receive the IQAudio Pi-Dac in todays mail. Unfortunately, the Raspberry Pi Volumio1.2beta distribution does not support the Dac without modifications. There are also features in MPD that don’t work just yet. The necessary audio drivers are not in the kernel. After several hours of working through updating the kernel and firmware I am now listening to high quality audio from the Raspberry Pi with the IQAudio Pi-Dac attached. I have not yet enabled hardware volume control, but that will be a future task. The IQAudio Pi-Dac uses the I2s interface for flawless audio. Possibly as the Volumio distributions mature this Dac will be supported directly. I surely recommend the audio quality and easy hardware installation. This Dac provides an alternative to the HiFiBerry, also a wonderful addition to the Raspberry Pi and it supports 24-bit / 192kHz Flac files. There is much more to be done. This is just a first start. I hope this Dac will be supported in future releases of Volumio.
The MPD Configuration under Audio Output does show ‘sndrpiqaudioda’ as the output option.
/etc/modules was edited by hand:
In MPD System settings do not Activate I2S driver as it will overwrite the /etc/modules file with the HiFiBerry values.
