RPI4 + HiFiBerry Digi2 Pro causing music playback problems

I have a Mac running Audirvana 3.5. My music files also reside on the Mac. Initially I used Volumio with a RPI4 USB connected to a DB Lab DAC and then analogue to the receiver. Playback through computer or Audirvana remote was flawless. However I have since developed a problem with the DAC therefore I decided to purchase a HiFiBerry Digi2 Pro and connect it to the RPI4 which allowed me to connect my setup optically to the receiver and use its DAC. Since doing that I now get a “pause/skip” at the beginning of each songs playback. Can anyone suggest a cause/solution to this problem?

Hello @mozart,

Can you send us a copy of the “Debug Info” when you have this issue? You can get it in Audirvana Settings>My account

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Dear Antoine, I forgot to mention that I control the Audirvana app on my computer by using your Audirvana A+ remote. As I pointed out in the aforementioned problem while using the A+ remote I had no problem with the RPI4 alone with my DAC, I only developed the problem when I switched over to RPI4 + HiFiBerry. Therefore since I am using the remote how can I see the debug info?

You can’t, you need to go on your Mac to get it.

Dear Antoine, Here is the debug info you requested but first a couple of things. I went back to the USB DAC approach albeit with a borrowed DAC and it works fine. So, somewhere in the middle of the debug is when I had it running with the HiFi Berry attached if this means anything. Also I have to have the volume set low because my receiver’s zone two cannot handle the volume w/o popping. Don’t ask, there are a lot of problems I am working through with my system. I may soon be at the point where I will replace everything and start over. Otherwise let me know if the “debug” info shows anything.

Max. memory for audio buffers: 29696MB is to much. You must try a much lower setting of the socalled “memory for audio buffers”
Try something in between 1048 and 2048Mb
Your operating system will be much more happy and will react positive to it.
Succes

Dear Mollie, I can see how it will improve my OS but are you suggesting that it might solve the problem of why my songs “pause/skip” during playback?

You can always try. In any case, it can’t hurt.

Yep, probably it will solve your problem.
When most memory is in use for Audirvana, there is most of the time not enough left for proper functioning of the operating system, especially in case of havy o.s. trafic!!!
Anyway a try-out is costing nothing and could be reversed in case it does not help.
Succes, cheers and happy listening!!!

I took your rather good suggestion and attempted to try it. However, now I cannot get the HiFiBerry portion of the assembly to play at all. Seems I have bigger problems here. I may have to go with an all in one streamer. perhaps I have too many components in the equation (Mac computer running Audirvana through a RPI4 with a HiFiBerry Digi2 Pro playing through a Volumio encoded SD card connected to a Cambridge receiver).

I see at your debug info that you seems to be using Volumio 1.0 which is very old.
At the moment Volumio software is up to version 2.9.15 !!!
Please update the rpi/volumio software to the latest version when the above is true!!!
How are you controlling the audio volume? By Audirvana, by Volumio, or by your receiver?

Do i understand right that you connect the rpi/dac (fixed) analog outputs to your receiver?

By which way is the output from your computer connected to the rpi/dac?

Hopefully we can figure out what the real problem is.

Cheers, mollie

Have a look at this too
URGENT UPDATE FOR 2.xxx USERS: please see this topic

It seems that using the hifiberry OS loaded onto the SD card is friendly to Roon however not to Audirvana which would explain why playback creates issues. Whereas Volumio loaded onto the SD card is friendly to Audirvana but not to hifiberry. This would explain why Audirvana plays through RPI with Volumio but not through hifiberry berry with hifiberry OS. What I’m trying to do now is to see if there is a work -a-round to get HiFiBerry to use Volumio. This would allow me to use the optical out on the HiFiBerry without having to change over to Roon.
