Streaming Roon via ethernet to A6, connected via USB out to Hugo TT2.
Is it possible to configure Eversolo A6 (1st Gen) and/or Roon, to stream upsampled PCM(768/705) or DSD512, via ethernet?
Thanks
As far as Roon is concerned, it will allow you to send what the streamer self-declares as being accepted. As far as the TT2 is concerned, it will accept DSD as input but is not cappable to use it without converting to PCM first IIRC.

It seems tha the A6 is identified by Roon as hanving max DSD256/PCM384.
Guess it may be difficult to be fixed via mere firmware update.
Using the “driver less” USB Audio Class 2 (UAC2) is not allowing for more. If Eversolo does not include a driver for the TT2 for whatever reason (maybe no driver exists) then that is what you get.

that’s not true, there isn’t such a limit.
The problem seems to be more on the DAC/USB side and not in Roon or the Eversolo.
For sure there is. UAC represents the USB side. There was UAC1 (for USB1, 96 kHz 24 bit) first, then an improved UAC2 (for USB2, 384 kHz 32 bit). If you need more, then this is outside the standard’s definition (and driver implementation) and you need to provide a driver for the audio device.
PS: UAC3 exists too I’m aware. IIRC does it have the same limits as UAC2 though and is not as widespread as UAC2. UAC4 is even rarer (currently non existent in personal audio (versus professional audio) devices AFAIK. It supports a far as I’m aware 768 kHz sampling rate (and DSD512 {DoP}).
No, why should work otherwise DSD512 or DSD1024 or PCM 1536 on a linux through standard ALSA over USB class 2?
You don’t have here any special driver.
Only for my exaSound e68 I need a special USB driver (also ASIO for the Mac), that it can handle DSD256 with eight channels.
No, the problem here is the Hugo DAC.
More like: The driver is already included in my Linux distribution. Also many Linux based streamers come with additional drivers included. But there isn’t a driver for each and any DAC in existence. The Hugo TT2 might be one of them. But why does it work then at all? Because a device independent standard (here UAC2) and standard compliant drivers exist.

Please understand my purpose.
I wanted to stream dsd512 or pcm768 to my A6, then connect a SRC-DX to the A6 usb out, and via the SRC DX’s double BNC to play dsd512 or pcn768 via the TT2 DBNC input.
You should ask Eversolo what drivers are included in their product or if they can name devices that support those formats and sample rates over their USB output. Ask about the SRC-DX if that is the device you want to use. That aside, the SRC-DX does not support DSD at all (according to its documentation).
I have ROON/A6 (1st gen) flawlessly up-sampling to DSD512 via ethernet (albeit over powerline adapter which is really NOT recommended by ROON)
I am quite happy with this setup … so far so good!

Can you specify how you connect your setup, from the Roon server, till the A6.
I have the Roon server conncted via mesh wifi netwok to the A6, from which I feed a TT2 dac via its A6 usb out
Please show your signal path as Eversolo capped its Roon support at 384/24 DSD256. This isn’t the first device to have less than stated specs when used via Roon due to stability issues. FiiO s15 is the same as are all their DAPs. Other streaming DACs also have this and only get max via using it as a DAC or via the internal player. To my knowledge this restriction is still in place for the gen 2 and no update was made to increase it.

In this case you are using the A6 as a DAC as well.
How and where in the chain are those powerline adaptors connected?
Thanks. Very strange and goes against what even Eversolo state.
He’s using its Roon Ready network input so the internal DAC according to signal path. Powerline adapters make no difference to a signal path they just convert network signals to travel over power lines.
