My DAC supports DSD yet Audirvana says not supported

I’m wondering why the Audirvana settings say my device SMSL USB Audio doesn’t support native DSD?

You selected dsd over pcm 1.1 in dac preferences little speaker icon at bottom right of main window?

Yes I had no choice because the settings says native DSD not supported.
I’m wondering do I need to update the USB firmware for this SMSL M500 DAC. I’m having trouble doing that on my MAC.

OK maybe I’m misunderstanding . If I choose DSD over PCM1.1, then that is using Native DSD? I thought there was a setting for raw Native DSD so that I didnt have to convert to PCM?

Audirvana doesn’t detect every dac in the world by default… mine isn’t either, i select dsd over pcm 1.0, because my dac stop at dsd128 if yours go further, select dsd over pcm 1.1. It is dsd playing, not converted, you can surely see that on your dac window when audirvana is playing

Thank you that helps grow my knowledge of this software. I still have a question though. Why is only PCM formats shown on my debug window? Shouldn’t I be able to play DSD formats directly?

SMSL USB AUDIO… Every input port supported DSD streaming, coaxial and optical supported to DSD64 by DoP technology via 24bit/176.4kHz SPDIF frame… Amazon your dac?

Your Debug:

Active Sample Rate: 768kHz
Hog Mode is off

DSD capability: Unhandled

Here is my debug while playing a DSD64 file… my dac is directly connected by USB
on my DAC window it is DSD64 playing
can’t tell you more… Maybe @Damien3 or others can help you more with Debug :slight_smile:

Audirvana display on my TV from Mac Mini without screen USB connect to DAC
DSD shown in, out, from Audirvana to dac display also…

Thank you for this. I’ve just discovered also on another post that MAC doesn’t support native DSD. So that’s why I can’t see it in the debug info I suppose.

Have you installed the ASIO USB driver?

No. Is there a dedicated USB driver for better data transfer to my DAC? Can you give me some more information?

You can download the Windows USB driver from here:
https://www.smsl-audio.com/upload/portal/20200511/202005111058548271.rar

Also make sure you’re running the latest firmware version.

Its a Mac and yes I have the latest firmware for that device thanks.

On the Mac just select DoP 1.1. You should be good up to DSD256.

Yes Thank you I’m really just wondering is there a loss of quality in not having native DSD and converting to PCM because of limitations of the MAC .

DoP is not converting to PCM. It‘s just packaging native DSD stream in PCM words.

Ok not sure what that means but it sounds like conversion to me. I will keep researching but haven’t decide whether purchasing DSD music is any better than PCM if I continue using Audirvana and my mac.

Nope, it just packs the unaltered DSD stream in PCM data packets. There is a a header that identifies it as DSD so that the receiving DAC can extract the DSD content.
