A couple people seem to have had success connecting a pi to a minisharc but there aren’t many details out there. Minidsp says that it should work on their forums.
I have volumio installed on my pi, connections have been made according to (minidsp.com/images/document … Manual.pdf).
pin 39 on Rpi (gnd) to pin 5 on minisharc (gnd)
pin 40 on Rpi (data) to pin 10 on minisharc (I2S_DATA_IN1&2)
pin 35 on Rpi (lrck) to pin 14 on minisharc (I2S_IN_LRCLK)
pin 12 on Rpi (bck) to pin 15 on minisharc (I2S_IN_BCLK)
I set the i2s driver to “Rpi-dac” in volumio (tried them all though). The minisharc is set to i2s input slave (minidsp.com/forum/suggestion-bo … -minishark).
I don’t get any input on the view meters in the minisharc software. Sending a signal into it’s spdif from a cd player works fine.
Am I missing something with volumio and the i2s output of the pi?
A pic of the setup is attached.
