Support for USB DAC inline AmpUSB?

HI,
NEW USER question:
I want to build a headphone amplifier using this USB-DAC:
https://www.inline-info.com/en/products/input-output/headphone-amplifier/9909/inline-ampusb-hi-res-audio-hifi-dsd-headphone-amplifier-usb-dac-384khz/32bit.
Couldn’t find any reference in support threads. Is anybody using this USB-DAC together with volumio on PI?
Thanks for help
Hans

We would need more specifics from that DAC, like the USB vendor and device ID and the output from “lsusb -t”.
I admit, a bit difficult in your case when you don’t have one.
Best advice: get in touch with the supplier and ask if he can give you the info.

Looks like it’s a Cirrus Logic 4392 device from the spec-sheet; I haven’t seen that many CL devices in the RPi audio world except for the Wolfson card…

Hi all,
just bought this USB-DAC (similar to first post + tube amplifier)

works out-of-the-box for most audio formats:
PCM: upto 384KHz
DSD over PCM: DSD64 +DSD128
DSD native : not working (only short tests)
