Splitting a digital usb audio signal possible?

[muslhead]

Is it possible to split a digital audio signal from a streamer without degradation of performance or signal?
I want one path to go to a separate dac (2 channel stereo) and the other to my A/V system. The goal is to use one streamer for both systems instead of having to purchase 2.

What is your communication link(s)?
HDMI? USB? coax?

Provided length/distance is not excessive, there should be no dropouts. Degradation of digital signals is not really a thing...

cat6 internet into the streamer and USB out.
What's the splitter look like? something like this example from Amazon work?

Looks like that device only passes data on one connector - the other is power only, for charging.

The closest I know of would be a USB hub. May not work the way you envisage.

yah, that was a bad choice, thanks.
This one looks better but still not sure if its intended for audio signals

Splitting USB is not possible. Switching it is. If you only want to use one DAC at a time, that is the way to go. If you want to send the same signal to both DACs at the same time, you'll have to use S/PDIF (or another source synchronous interface).

One dac at a time is fine. what do i use to do that? just a usb hub with switches?
Alternatively, in case you know, on a raspberry pi4 there are 4 usb ports, are all of those ports active at once if not, which one (If there are more than one connected) gets the signal since there are no switches? Sorry for the misdirection but i thought i would toss it out there in case you know.
Thanks

Topping d10 has usb in, toslink, coax, and rca analog out. All three are acrive during playback.

yah, already have my dacs. there are digital interfaces that do that same thing but they dont have 2 usb outs, just 1 with toslink, coax rca.

If you connect multiple DACs at the same time, e.g. via a hub, the operating system will present both to any applications. Your streaming software might support selecting which one to use, or not. If not, a USB switch may be the most practical solution. These can be found on Amazon at little cost. There is nothing audio specific here.

You need a USB Switch. I have this one...

It works well, I used this to share a keyboard, mouse and USB headset between my personal PC and work laptop during the early days of lockdown (I have the same functionality built into my monitor now).

i have one i just wasnt sure it worked with audio but as mansr stated, there is nothing audio specific here.

That's the opposite of what the OP needs.

You think the streamer is going to act a USB host?

The rasp pi4 has 4 usb (2-3.0 and 2-2.0) ports. I couldnt find confirmation but i am assuming they are not all active at once. If i had 2 dacs i would test it.

They are all active at once. Your DAC and AVR will be seen as separate devices by what ever streaming software you are using. You just need to select the output in the software.

Here's MoOde giving me the option of outputing to HDMI, headphone jack, Topping D50s (USB) and Tempotec Sonata HD (USB)...

thanks but if they are all active why do i have to select one?

That's what they are.

The USB ports are all active, by you need to tell the system where to send the audio data.
