It will do with RedOS (setting in compatible
modus) and Ropieee.
Here you’ll see in Roon two endpoints: One for the USB and one for the other digital outputs.

@Aleksandr_Levkin I²S on a Raspberry Pi? which Hat are you using, because I²S is not native on a RPI I think.
4 version of pi. Holo has designed the i2s output to sound the same as usb. According to many, I am not the only one who prefers this output.
Holo uses a Pi4 compute module with its own electronics. It is not a Pi4 in the sense of a SBC. There are important differences. For instance the Pi4 element can be bypassed when used as a DDC. This demonstrates that the electronics are totally independent of the compute module element but those electronics can be harnessed by the compute module with the right software loaded.

Is there any news on red dsd1024 support for usb and i2s?
Hello!
I am using the Holo Red into my McIntosh DA1 via USB and under DSD mode in the Holo settings it gives 3 options
PCM, DOP, and DCS.
What is DCS? I also cannot get Native to appear.
If anyone has any info, much appreciated!
It’s probably related to what is mentioned here:

McIntosh don’t have Linux support to get Native DSD, the Holo is a Linux based streamer so your limited to UAC 2 spec which is limited to using DoP only for DSD.

what was the outcome of the comparison ?
Because of the way the Red works it has two modes. One where it is transparent and references the USB DAC as the endpoint. The other is where it references its own internal USB as the endpoint. In this mode I am pretty sure it should present a Native option although that may still be limited to the maximum DOP numbers. The problem is I can’t prove it as I don’t have anything with the limitations of the DA1.
The mode I am talking about is where the Red will still be visible as an endpoint when the DA1 is switched off.
Hi Henry,
I am using Holo Red with AES/EBU connection with the Yggdrasil DAC. On AES every time I when I try to play songs that are 24 - 174 or 24 - 192, I get like 8 relay clicks instead of the normal two relay clicks from the DAC trying to lock the signal. This does not happen with USB. Does this mean that the Holo Red is the problem or the DAC? Or neither, it’s just normal behavior. I have tried different OS’s on The Red, like Roon, Volumio etc. I even tried playing local tracks and it does the same.
I use a RED into AES/EBU of my Devialet amp. It doesn’t do the same as yours, but it does seem to take the first second of a song, that is a different bit rate than the last, to ‘lock in’. Once locked into that bit rate, anything else with that bit rate plays instantly.
Long story short, I believe it’s the RED.

That strikes me as being an issue with the DAC locking on. If you had another DAC to try it might prove that. Or of course another streamer. But I don’t think it is possible to speculate as to the possible problem. Only to change things and see what happens!

Funny how we answered the same question in 180 degree different ways. Good luck finding out who’s right Flav!

I tried the same DAC with Wiim and Bluesound over COAX because they only have COAX and I don;t have this issue. I also tried the streamer on 4 other DACs and on three of them it’s making the same and on one of them is OK :)))
I ordered a new Red, actually a friend of mine and I will test with that one also. On USB it’s working ok, so no issue. I will probably have to deal with living with USB only.
I can’t speak for your DAC, but on mine AES?EBU sounds more natural so for me it’s worth the occasional stutter. If I want to listen to the first second of the song, I can always re-start it.
True, and a good idea, the only thing that messes with my head regarding this is when I leave for example Roon to play by itself, there are lots of songs that are 16-44 and then 24-192 and the lock/unlock is kind of annoying but you are right, probably I can live with it like this. As for the DAC, I honestly don’t want to change it just because of this, it’s quite a good sounding DAC for my taste at least.
Here is my problem with the possibility it is the Red. I can reproduce the problem with a Spring 3 by simply turning the DACs PLL on. Turn the PLL off and the problem all but vanishes. My point is the delay can be the normal part of the way a DAC operates but would require the Red to be faulty which would be very unusual. This does not manifest itself with USB because that is asynchronous. But an AES/EBU DAC has to slave itself to the source and if this requires a sample rate clock change this takes time. Roon comes with adjustments to mitigate this. There will be a delay but if set correctly it will not cut off the first few moments of your audio.
As an engineer I say ‘never say never’. In my view it is more unlikely to be the Red and I would play the percentages and look at the DAC first. But I’ve been wrong many a time (but right most of the time). So my instinct is to go with the percentages. Just be methodical!
Would it help to upsample everything to the same sample rate in Roon?
