Chord devices ASIO native DSD512

Dsd over pcm 1.1 will do 512 on PC. And yes it is dsd.

Cool, thx. But the issue with DSD512 is still there: I can’t play it natively.

DoP 1.1 (DSD over PCM) is a PCM carrier file format for transfer of native DSD data… The DoP 1.1 PCM carrier sample-rate for DSD256 is 705.6kHz… the DoP 1.1 carrier sample-rate for DSD512 is 1411.2KHz

You can’t play DSD512 via WASAPI as shown in the screenshots.

Nope, I can’t play DSD512 with native ASIO (as show in the picture it is seen as compatible). With WASAPI, it is converted to PCM because Audirvana sees it as not supported. So the issue is with ASIO, cause that’s what I’m using.
If I play with ASIO, like I said, it’s either playback error or stuck at 00:00.

Have you downloaded the Windows driver for Hugo available on the Chord site?.. The ASIO handshake report in Audirvana is showing PCM sample-rates to 1536kHz… This does not look correct if the Hugo 2 is spec’d to 768kHz … I got tripped-up by the ASIO handshake report, when stating you could support DSD512 via DoP 1.1 … It appears only raw native 22.4MHz DSD512 is supported. The DAC needs to support 1411.2kHz for DoP transmission of DSD512.

From the Hugo 2 description on the Chord site:

PCM support: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz, 717.6kHz, and 768kHz. 16 – 32bit

DSD support: Native playback supported. DSD64 (Single) to DSD512 (Octa-DSD)

@Antoine - This appears to be a bug in Audirvana:

@TheSpidyFlash, you should not be seeing the “Native DSD streaming method” option in ASIO, only in WASAPI. But when you first go to WASAPI settings, then to ASIO, Audirvana retains the “Native DSD Streaming Method” option in error. (Also erroneous resolutions are reported, like 1536kHz PCM for Hugo.) Try going to Kernel Streaming, then switching to ASIO and see whether you still have the “Native DSD Streaming Method” option or whether it has been (correctly) eliminated and whether Audirvana is now showing correct PCM and DSD resolutions highlighted for your DAC.

Hey @Jud,

Nope, it doesn’t work. Whatever I do, that 1536kHz PCM and Native method option is still there. And yes, I already stated that I installed the official drivers, without them there are no ASIO drivers available.

Do you have any other suggestions?

LE: I reinstalled ASIO drivers, and made sure that they were uninstalled (so no ASIO driver found), but it’s the same error.

Thanks,
Robert.

Just wanted to confirm that DSD512 is working fine on my Hugo 2 :slight_smile: .

As you can see, it plays perfectly with JRiver with Native DSD.

Hi @TheSpidyFlash,

I need to contact Chord regarding this, it seems something is odd with their ASIO driver when we look at it with a Chord device in our development environment.

Thank you. Please keep me posted.

You may also want to contact Chord about your issue… :wink:

I did. I’ll wait and see if they can help.

From Chord:

Thank you. We are now working directly with Audivarna on this.
All the best

Yes, I’m in contact with the technical manager on this case :wink:

Cool. Please keep me posted.

Hi @TheSpidyFlash, just a quick note to inform you I sent an email to the technical manager of Chord, hope to get an answer from him soon.

Hey,

Any updates on this?

Hi @TheSpidyFlash,

We sent technical information to Chord in December, but I couldn’t follow up as I’ve been bsuy since then. I will ask them if them found time to look on this.
