Topic: ADI 2-DAC sound breaking up

I'm using the ADI-2 DAC connecting with the computer by USB. From the beginning, I found some ''pop'' noise when playing music, but it can solve by install the driver. Unfortunately, after installing the driver there is the other problem which is the sound will be breaking up when playing music. I tried to set the buffer size to 2048 samples in the driver software but it does not work. Someone knows what the problem is and how to solve it? Thank you.

Driver version: 0.9700
Firmware: V.33

Re: ADI 2-DAC sound breaking up

You provide only very few information about your setup
- hardware (CPU, Memory, Mainboard, Graphic card)
- operating system (i.e. which exact version of Windows 10)
- what application are you using for audio playback
- does this application support ASIO and did you really select the RME ASIO driver
- what sample rate is in use for your audio content ? The usual 44.1/48 kHz or higher ?
- what USB cable you are using
- to which USB port you connect the ADI-2 DAC

Did you try a different USB cable ?
Did you try all USB ports on your computer ?
The USB ports that come from the chipset of your mainboard are usually the best.
I would try all USB2 and USB3 ports.

How is the CPU load on your computer when you playback audio ?
Which Energy Profile are you using (assuming you use Windows) ? Can you try full power for max performance ?
Are you browsing the internet when the pop appear ?
Do you use Wireless or do you have cabled network access ?

Did you check your system with tools like LatencyMon, how much headroom the CPU has, to transport audio.
If the kernel latency timer values are too high or have high spikes, then this means that a process or driver is consuming too much cpu time and blocks the CPU for too long. If the audio driver or process is on the same core, then audio loss is much likely. LatencyMon also supports you to find drivers, which run for too long.

Computer spec:
CPU: AMD Ryzen™ 5 3600
RAM: Corsair VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 3200MHz C16
MB: ASUS Tuf B450m pro gaming
Graphic card: Powercolor Red devil RX5700XT

Operating system: Window10 professional (ver. 1903)
Audio playback software: Foobar2000 v1.5.1 with ASIO
The sample rate of audio: 16/44
USB cable: FURUTECH GT2 PRO connect with Computer mainboard USB port (i tried all the USB ports on my computer)

About the CPU load when playing music by foobar2000 just between 3~6% (didn't use the other software but with a cabled network)

The LatencyMon said ''your system appears to be suitable for handling real-time and other tasks without dropouts'', It is means there has no problem?

Not so convinced, you need to look at the values.

Re: ADI 2-DAC sound breaking up

I have the same problem with ADI 2 DAC-fs. Especially when I stream music through the windows app Deezer, but it also happens when I listen music locally through the Foobar 2000. About every 2-3 minutes it stops for 1sec. Like buffering.

Search for X99 and its various problems in this forum.

Re: ADI 2-DAC sound breaking up

As far as I can find on the forum the problem is with Asmedia usb drivers. And I should find a usb port that is on an intel controller. Am I right?

Thanks

Re: ADI 2-DAC sound breaking up

Thanks for the answer, just one more question. Would it help to insert a pci-e usb hub card without changing anything in the bios and around the graphics card driver?

I found in the forum that people are suggesting sonnet cards for similar problems.

Re: ADI 2-DAC sound breaking up

What mainboard do you have ?

You could either use this sonnet USB3 card, which you mentioned above (https://www.sonnettech.com/product/alle … 4port.html) where 4 ports share one USB3 controller.

But then you should not connect other devices to this card, so that the USB3 controller is really dedicated to the recording interface. Or you need at least to turn off devices, while recording.
For this card the requirements for PCIe sockets are not so high, PCIe 2.0 x1 (x1 means only one PCIe 2.0 lane from CPU or chipset required).

Alternatively you could also use an USB 3.1 gen 2 card with UASP support. This card here has 4 ports and 2 USB 3.1 gen 2 controller (ASM2142). https://www.startech.com/Cards-Adapters … EXUSB312A2. So only 2 ports share one USB3.1 gen 2 controller.
But for this high speed card you need PCIe 3.0 x4 sockets (PCIe sockets with at least 4 PCIe 3.0 lanes from either CPU or chipset). Preferred from CPU.

With such an USB 3.1 gen 2 card supporting UASP you would be more flexible.

Then you can isolate a recording interface behind one controller and then you can use the other two ports
of the other USB controller for other stuff like high speed backup to an external USB3 disk.
If you plan to make use of this, then you need a case that also supports USB 3.1 gen 2 and UASP like this here:
https://www.startech.com/de/HDD/Gehause … ~S351BU313

ASMEDIA controller are also fine, only the initial / old USB 3.0 controller (now being called USB 3.2 gen 1) had issues.
Here an overview about old and new naming and capabilities:

Re: ADI 2-DAC sound breaking up

Hi Ramses,
thank you for answering.

Only ADI 2-DAC will be attached to the usb hub.

My mainboard is:

CPU: i7 5930k
RAM: Corsair 32GB
Graphics: RTX 2080

Re: ADI 2-DAC sound breaking up

You have a workstation board with a lot of PCIe lanes and free PCIe sockets.
If you only need it for the recording interface, then simply take the sonnet card with FL1100 chipset.
I hope the FL1100 chipset will work also very good in USB2 compat mode.
I would give it a try.

Re: ADI 2-DAC sound breaking up

Thanks Ramses, I'll try with that solution.
