Hi Res file downsampled to 48k on V3.5.5 from Audi/Tidal

🖥️ Audirvāna Device connectivity

Hi. All my Flac MQA Hi res files show up as 48k on my Mac Digital Preamp. If I play the files through Tidal, they show up correctly as Hi Res.

On the bottom left of the AV screen, it says FLAC 24/96, and the bottom right it says, 24/28.

Tidal is set to master and exclusive mode.

Thanks!

I’m going to assume you mean 24/48 not 24/28, You must have your DAC set to MQA decoder. So you have your DAC doing the unfold and restoring the file to 24/96

If you set your DAC settings to non MQA in Audirvāna preferences the unfolding will be done by Audirvāna

Could you share the Debug info?

MQA is 24/48. It will be decoded to 24/96.
Depending on the settings in Audirvana the decoding takes place in Audirvana, the DAC or not at all.

Is your DAC a decoder or a renderer?

Edit:
If you mean the McIntosh D1100 as a digital preamp. As far as I can see it doesn’t support MQA. Which means Audirvana has to do the decoding. In the Audirvana settings, the DAC must be set as a non-MQA device.

Thanks for helping!

My DAC is a McIntosh D150, non MQA. Tidal is set to do the unfolding.

Change this to ‘not MQA’

Where in Audirvana 3.5.5’s preferences would I find that option? I don’t see it under streaming. Thx!

It’s with the DAC hardware. It’s about specifying whether the hardware can do it. Not about the streaming service. In Audirvana studio it looks like this. For 3.5 I have to boot a old laptop.

I still have a 3.5. version installed.

You don’t find it under streaming. You will find it in the settings of your sound device in Audirvana 3.5.

Click on the speaker icon below right. After that click on the ‘>’ sign next to the name of your Mcintosch device (on my screen it says ‘Topping’ because I don’t have a McIntosh):

You see the next screen. In your case the title should be something like ‘McIntosh’ of course:

Choose the ‘not MQA’ there.

NOTE: You have to stop playing music in Audirvana, otherwise you can’t change the settings of your sound device!

Since it is not MQA, put auto-detect at off also…

The DAC finally sees the hi res files from Tidal. Thank you so much!
