SMSL SU9 Support (ES9038 Pro)

Good morning everyone
I’m planning to buy one of these

which is based on a es9038pro chip.
I was wondering if it’s supported by Volumio (sorry for opening a new topic btw but i was unable to find something similar except from some info according to su8 which is quite old)

According to this

this is the best DAC money can buy at this price point and can compete much more expensive ones.
My intention is to build a solution based on a

NUC running Volumio==>SMSL SU9 Usb DAC also used as a preamp==>Rotel RB1552MKII Balanced==>DIY 3way speakers.

Any info will be much appreciated
Thnx in advance

Kind Regards

We can’t say without more info, perhaps telling us it is for a PI or a PC or some other community supported volumio board would help us :innocent:

DAC vendor id VID (and sometimes product id PID) from the used DAC are crucial.
Without them we can’t say whether it will detect the proper DSD capabilities in the environment used.

vid/pid you will get when you do

lsusb

while your DAC is connected.

I just received an S.M.S.L. SU-9 and it does not seem to be working with volumio on RP4b. It shows up as a valid output device, but playback isn’t working. This is the output of lsusb and stream0:

I’m happy to report that I found my problem and the SMSL SU-9 is working without issue. My RPi4b case was blocking wifi signal and making everything run very sluggishly and not allowing music to play from my cifs server source. I removed the case and everything works well. Cheers and happy listening!

Correct, Thesycon (and Xmos) devices are properly registered as DSD capable since a a couple of years already. It had to be something else.

Yes it does.

Thank you . DAC will arrive in my system soon.

Hi notyad and Lacaxxaa, I am going to buy SMSL SU-9 and pair it with RPi4B Volumio like you do. Can you share whether they work perfectly together? Any small issue that I have to pay attention?

hi everyone, my smell su-9 can’t support 768kHz just shown 384kHz I use cable coming with box and installing the driver from the website
