Allo USBridge Signature

It would be good to know, right now, I am having to use a version of dietpi that is based on an old kernel. I found the following on Allo’s website.

http://3.230.113.73:9011/Allocom/DietPi/rpi4.14.92/ - there is a message which says -

"based on feedbacks USB dacs observed dropouts issue in 4.19.y kernel.

Dietpi OS image based on kernel 4.14.92 is available in this location for testing"

Using this build of Dietpi the popping and cracking is better but not completely gone. I have a thread open on audiophilestyle. I was also advised (as per @oneofmany above) to -

see post 913 here

Its what I did, helped another guy too. The other guy said it was the config.sys changes that fixed it for him.

I’d be curious if it makes a difference for you

I haven’t done this ‘fix’ yet as I wanted to see what Allo said about it first.

Shanti:

I quite agree. I think if i knew how big and how ugly, I would not have ordered it!

I am considering the Allo USBridge Signature, with NAA, how is that working nowadays? @jussi_laako ?

For the ones of you guys who have the USBridge Signature, any opinions on sound quality compared to other streamers?

I can’t comment on NAA, but I can say that the sound quality of the USBridge Sig as a regular Roon endpoint is shockingly good. Noticeably better than the Pi3/DigiOne it replaced.

Note that I did have issues before I started using the custom ethernet driver from Allo.

Just received my USBridge Sig. Powers up, doesn’t seem to connect to network. Using ethernet, have green light, can see it in my Comcast XFi app, can see it’s IP address. But not showing in Roon, and that IP address shows as not connected. Thoughts? Thanks.

Hi @Tim_Werner,

  1. Have you gone into settings / audio and enabled it?
  2. What OS are you running on the Sig? (e.g. Ropieee etc?). You might well need to do some config at that level too.
48

is your DAC connected and ON?

  1. It doesn’t show in Roon at all; it’s not showing as an option to be enabled in Settings > Audio.
  2. DietPi. Can’t get to interface, when I hit the IP address, I get the “this site can’t be reached” screen.

Yes, it’s connected to a PS Audio Sprout via USB.

51

… and it is ON, right?

also: DietPi does not have a web UI: you must use ssh to configure it

or… burn RoPieee to a microSD card, if your USBridge will only be used as Roon endpooint :wink:

Hi Again @Tim_Werner,

Apologies in advance if you’re across all this already. If you’re not, then I hope it will be of use. I’m running ropieeeXL on my Sig. It acts as a Roon endpoint, but the XL version of ropieee also has the option to turn the device into a spotify or airplay player – very handy.

Ropieee images are here: https://ropieee.org/software/

A great “how to” guide is at the bottom of this page (follow the link at bottom when you get there) – you can ignore all the parts about adding a display: https://ropieee.org/getting_started/

When Ropieee is installed and running (wait 5-10 mins for the fast blinking on the SIG’s LED to settle to slow 1/2 Hz), you can connect to http://ropieeexl.local/ on your network. Then make sure you have the “Audio USB” slider turned on (screen grab from mine below).

Whatever OS you have flashed to your SD card, it’s very likely that you’ll need to navigate to the SIG’s webpage, and configure it to look for your DAC. You should be able to look at your router and see the IP for your SIG, which you can then enter into your browser.
