I have installed
Raspberry Pi 4 Modell B 4 GB RAM
HiFiBerry Digi+ Pro
Pi4 is with ethernetcable online
Roon shows unit and is playing
But here is no audio out signal on coax and optical
Roon-setting and Ropieee setting
Coax and optical cable are ok
RME adi-2- Pro does not show any input signal
Do i have to do any setting to enable audio output on Hifiberry digi+ pro card?
Have you tried disabling volume control? So setting it to ‘fixed volume’?
Can you send me feedback? You can find that option on the ‘advanced’ tab.
Also, have you tried different sample rates?
No this is a HAT with coax/spdif out.
44,1/16 is working
192/24 no output
Ich will do some more testings, what is working and what delivers no output.
192 will for sure not work on optical. That’s usually limited to 96k.
Im am using both - optical SPDIF and coax AES
Testfile
Mp3 44,1
Both outputs are fine with volume control- fixed volume
Volume control DSP - terrible noise on AES
FLAC 96/24 - fixed volume
No AES, SPDIF OK
FLAC 192/24 - fixed volume
No AES, NO SPDIF
Judging from the pictures above I think you have to change SRC setting on your ADI-2-PRO to SPDIF?
SRC is fine - i am using both inputs
AES for headphone (Rasperry-RME-(StaxAmp)-Headphone)
SPDIF optical for loudspeakers (Rasperry-Antimode-RME-Amp-Loudspeaker)
AES should work with 192
SPDIF optical with 96
If i plug out headphone, RME automaticall switches from AES to optical for loudspeakers.
Each setting has different DAC-Settings and PEQ-Setting on RME - this is a great feature.
So Roon should set ist to 96, or Ropieee should do so.
AES should work with 192.
I think the Digi+ will just output SPDIF over toslink or cinch? The RME is a great device but it is also complicated (I tried it briefly). It think it requires to disconnect the Sample Rate Conversion from the AES input by setting it to SPDIF to work with your Digi+ HAT.
From the ADI-2 manual
8.6 SRC (Sample Rate Conversion)
different clock-sources. For example having the ADI-2 Pro synchronized to an AES signal, a CD player connected to SPDIF input can only be used when the SRC is set to SPDIF. It then decouples the clock of the non-synchronizable CD player, preventing clock problems and drop outs. As the incoming clock phase is no longer fixed when the SRC is activated, the SPDIF Sync state in the State Overview screen will always show lock.
I now updated the kernel, but problem still exists
There is also crackling noise on AES
What do you mean with ‘updated the kernel’?
I made some updates on Rasperry with max2play after reading this information (link below)
Hoping to get also rid of the terrible click noise on AEs
Now i have kernel version 5.4.81-2-SPCKFSH-v7l+
as per manual it should be set to spdif?
