No DSD output via optical

Kamin68 · March 7, 2023, 8:02am

Hello,
I searched the forums and the Internet but couldn’t find an answer.

I have a Douk AUdio Pro DAC (Douk Audio U2 PRO XMOS XU208 USB to COAX/OPT/HDMI Converter Digital In– doukaudio) connected to my Mac Studio (M1 Max). My DAC is connected to my amp via optical out. I tried many settings but no sound will come out of the device event though my DAC is DSD compatible.

Any suggestions?
Thanks

Optical output is not DSD capable.

Kamin68 · March 7, 2023, 12:21pm

Thanks, I didn’t know that.

Any recommandations to link my Mac Studio to my amp in order to play DSD files?

bitracer · March 7, 2023, 1:43pm

USB is your best bet. If you have multichannel amp then HDMI is also an option.

Kamin68 · March 7, 2023, 8:57pm

I only have RCA line in input and optical.

Am I out of luck or is there a way to use an adapter of some sort?

bitracer · March 7, 2023, 9:02pm

You can always convert DSD into PCM on the fly in Audirvana.

Kamin68 · March 7, 2023, 9:17pm

Yes I can. But by which means do I send the audio out to from may DAc to my amp since I only have opticaé and line in?

bitracer · March 7, 2023, 10:13pm

It will be sending PCM, so yo can send it via the optical cable. It will the depend on the max sampling rate supported on that interface though. It’s worth a try.

Kamin68 · March 8, 2023, 5:32am

Ok so we’re back with my original question.

I already set Audrivana to send via DoP (PCM 1.1) and I have no sound coming out. Evrythong worked fine when I was on iMac (2015), but not anymore with my Mac Studio.

Any ideas?

bitracer · March 8, 2023, 10:22am

You need to set “convert DSD to PCM”.

Kamin68 · March 8, 2023, 10:28am

It is already set.

bitracer · March 8, 2023, 12:12pm

Not DoP. That’s DSD over PCM. It’s DSD encapsulated in PCM words. You need to really convert DSD to PCM.

Kamin68 · March 8, 2023, 1:36pm

Convert to PCM isn’t working either.

I must be missing something. Does my setting look ok to you?

Thanks for your help by the way

RunHomeSlow · March 8, 2023, 1:41pm

Can your turn hog mode on?

bitracer · March 8, 2023, 1:47pm

Reduce the pre-load cache to 4000MB.

Kamin68 · March 8, 2023, 2:22pm

Turned Hog mode on, same result and reduced pre-load cache. Here is my debug info updated:

Have you tried using this setting? I’m not sure what your system is capable of but perhaps give it a try.

DOUK info:

I2S output supports all sampling rate while S/PDIF supports 192KHz and DOP DSD64 at highest.
The pins of 12S is suitable for the HDMI interface of most PS decoders (not guarantee 100%).
Please set the volume of operation system to maximum(100) if you want to listen to DSD music.

RunHomeSlow · March 8, 2023, 2:43pm

You are playing a 352 pcm file or is it a DSD256 converted in pcm?

OffRode · March 8, 2023, 2:50pm

With USB input and TOSLINK optical / coaxial /HDMI 12S output(can output at the same time), can work well with DAC, preamp, amplifier or speaker. Adopting XMOS XU208 chip solution, with 1000MIPS random access memory much higher than U8 (500MIPS), and more stable than Italian Amanero solution and coaxial output supports DSD DOP.
Output interface with DSD ON function can match the decoder that needs DSD ON signal to decode DSD songs, supporting 44.1K-384KHz/16-32 Bit sampling rate and DOP DSD256 at highest, better signal process brings higher sound quality.
High-quality components are used to ensure better performance, such as ultra-low noise LDO regulated power supply, LVDS differential chip, gold-plated coaxial interface, OS-CON solid capacitors and Panasonic FC filtering and decoupling capacitors, the contact internal resistance is smaller and the data transmission is more reliable.
USB interface can be used as signal input and power input at the same time, and with external DC 5V input (with priority) that can be powered by phone charger or power bank, easy to enjoy HiFi music any time and any where.
Mini size with exquisite design, with PCM and DSD indicator easy to show the output format, black aluminum alloy cases look more cool and fashionable, very suitable for desktop audio device to use.

I’m not certain what the ad copy is exactly saying, I must need some more coffee or a translator or perhaps both

@Kamin68 maybe you need to be plugged with coax cable?
