Different Volume Levels On Different Computers

Connection with external Audio Devices Streamers
1

Hi,
I have Audirvana installed on my two Macs, an iMac and a Macbook Air. Using the remote app on my iPad I compared using the two of them with exactly the same settings, retrieving the same tracks from my network NAS and playing through my network streamer to my RME ADI-2.

I was very surprised when I heard a very apparent volume difference between them. When running Audirvana on the iMac it was a lot louder than running it on the Macbook Air?

I have checked all the settings and they are exactly the same, volume is 100% on both and there is no volume levelling engaged.

Any ideas? Am I missing something obvious here?

Hello @ctrlm,

Can you send me a copy of the “Debug Info” for your two devices? You can get it in Audirvana Settings>General>Debug Info

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

If you don’t use the ToneBooster Equalizer, does the volume is the same or not?

Hi Damien,

that’s a good point, I will try it later and let you know.

I appreciate your support, even though it’s not exactly a major issue.

Cheers
Mark
