About the sound of volumio

Volumio Information

Volumio Version:2.699
Hardware: pi4 * 2 pcs
DAC: hifiberry dac

hi volumio team

volumio’s hifi effect is very good!
But I found that volumio has a strange phenomenon…

I have two pi4s. When I install volumio on one pi4(A), everything sounds perfect…
But when I inserted the (A)SD card into another PI4(B) to play…PI4(B) sang very well.
Not at all like the effect of PI4(A)… Excuse me, what is the reason? What should I do?

PS. I only have one power supply, one SD card…two PI4

2 same dac?
Same amp?
Same speakers?
Same room?

Your description of this is so vague it’s hard to know where to start.

Can you more clearly explain the issue?
How was the sound different?
Are both the R Pi 4s the same model and configuration?
Was the same DAC used? How is the DAC connected?

My device is:
pi4 *2
sandisk 16g *1
hifiberry dac 2
Headphone amplifier
1
akg 702 *1
I just pulled out the SD card from pi4 (A board)… inserted into PI4 (4 board)

If you want PI4 (B board) to play the effect of PI4 (A board)… SD card must be re-swipe IMG and RUN on PI4 (B board) for the first time!

I want to know. What did the system do when VOLUMIO was turned on for the first time?

The. First time you use a fresh install of Volumio, it performs a resizing for a partition in order to be able to use all the space to store your music.

I think you didn’t understand my question…
I am the same sd card… The same volumio system is used between two pi4!

The docs say what happens.

I still don’t know why the same sd card exchanged with different pi4 affects the sound…

I think you should do an experiment.
Get a second micro SD card, create a fresh image from the same download you used for R Pi A
Boot R Pi B to that fresh image and allow it to complete first boot.
Then see how it sounds running that second micro SD card VS R Pi A running the original card.

Report back on your findings.
Try to describe what is different about the sound instead of saying “sounds perfect” vs “sang well”.

这个方法我已经试过几次! 结果一样!
似乎声音的完美只能是sd卡第一开机引导的pi4 !

你也可以试试看我的方式… 用一张sd卡去引导pi4-a卡…
在将sd卡插入另一张pi4-b卡!

I have tried this method several times! The result is the same!

It seems that the perfect sound can only be the first boot of the SD card pi4!

You can also try my way. Use an SD card to guide the pi4-a card

Insert SD card into another pi4-b card!

I can’t understand either.
Where is @volumio when you need explanations for the weirdness?

The question is still are the both Raspberry Pi 4 the same. Please give which version number you have and ram seize. see https://tutorial.cytron.io/2020/02/22/how-to-check-if-your-raspberry-pi-4-model-b-is-rev1-2/ how to find out. next is to see if there is a different in the eeprom bootloader https://www.raspberrypi.org/documentation/hardware/raspberrypi/booteeprom.md . The firmware should be the latest, as there are many changes compare the first release.

The question I asked has nothing to do with the hardware version !

Because I’ve confirmed. Both raspberry pies have the same hardware version!

I’m curious. Why didn’t the volumio team answer this question? Was it busy? Or didn’t think it was a problem?
