I’m having trouble using the Transport Pi Digi streamer with Volumio. The set up- UcPi for power, Rpi4 loaded with the latest version of Volumio, Transport Pi Digi on top. The DAC is a Denafrips Enyo (no I2S input).
I’m trying to connect the streamer via SPDIF coax to the Denafrips. There is no option to select SPDIF output in the Playback Options tab, only HDMI and headphones. I previously had the same DAC connected to the RPi via USB and everything worked as it should. The reason I bought the HAT was to use it via SPDIF for the benefit of reclocking the signal. I have searched the forums, no joy. It seems this may not be compatible with Volumio but, I hope so.Thanks in advance for any help.
Thank you for the reply. I did see that but didnt know what is was.
I’ll try it out when I get home.
Worked for me!

I’m subscribed to the trial period on Volumio Premium on a rPi4B, Ian Canada TransportPi Digi/II plus HdmiPi Pro II outputting I2S into a Gustard X30, DAC in Volumio is set to HiFiBerryDigi plus, as specified in Ian Canadas Quick Start guide for TransportPi Digi/II - all I get is Alsa error. Factory reset - same problem. Switching to headphones and back to I2S DAC - same problem. I am very close to deleting Volumio, cancelling the Premium account and looking for something else more reliable (although maybe that doesn’t exist, who knows), currently I think Volumio is unusable for IanCanada streamer…
Have you tried the bèta what @Darmur suggest.
Yep, I tried updating to the 3.758 beta, no change, I still get “alsa” error when I select Hifiberry Digi+ Pro as the DAC
you could try hifiberry digi as a driver.
If all jumpers, clocks and connections are correct on both Ian Canada boards, and the power supply has enough volt and amps then I don’t know.
Using “HifiBerry Digi” gets the same “alsa” error message as “HifiBerry Digi+ Pro”, although using “Generic I2S DAC” works albeit I don’t know how well it is working…
The only jumpers I changed were on S1 on the HdmiPi Pro II to set the I2S pins to match the Gustard X30 input.
The only connections are the master clock from the HdmiPi Pro II to the Transport Pi and the Mute link.
Am I missing something?
If I’m not mistaken generic i2s is hifi Berry dac.
If it works I would leave it that way.
or else ask Ian Canada why it doesn’t work with digi+ pro.
I wasn’t wrong it is listed as hifiberry dac

Many thanks for this…
you could pin your problem down to the beta kernel 6.6.
then select hifiberry digi+pro and try to play something, as soon as you get the error make and post a log there.
This way you also help the beta test kernel 6.6.
