Yesterday received and connected my new Vivaldi DAC .
My Fanless PC with JCat network card and USB card connected to the 2.0 USB input and everything worked fine right away.
Roon also immediately recognized the DAC and plays all formats well.
So Windows 10 Pro automatically recognized and installed the Vivaldi DAC.
But when I look at in my PC by the ādevice managerā, I see that there is an error message: The drivers for this device are not installed (code 28)
So I installed the dCS driver as stated in the manual but the error message remains.
What can that be?
I see that the audio path does recognise the audio-class 2 device, and I assume you get sound out of the DAC. It even reports the correct name. So far so good.
Iām suspecting that what you see in āOther Devicesā is not the audio part of the Vivaldi, but another device on the same USB bus for some other purpose. āDFUā could mean Device Firmware Utility, but Iām guessing here. Contrary to Rossini, since Vivaldi DAC does not have a network connection, firmware updates have to be done through the USB port so there must be a path inside the equipment to enable that - thatās my guess.
I donāt have a Vivaldi DAC in front of me currently, but Iām guessing that this is partially due to MQA support in the DAC. Weāre required to present an additional interface via USB that the player can query in order to find out MQA capabilities and get MQA status. It presents as an HID device. Iām wondering if on first connection Windows didnāt recognize it and that didnāt get overridden when you installed the dCS driver.
You could try uninstalling the dCS driver and deleting the device in device manager. Pull the USB cable, then install the dCS driver. That might get it going correctly.
Regardless, this has no impact on playback so unless it causes concern Iād just queue up another track and enjoy it
