Digital noise when streaming audio via USB-B.

[patkedParticipant]

Hello

The current firmware (it is almost 3 years old) does not correct the noise in streaming if you have this problem …
In any case on LINUX (I don’t use windows or mac).

The solution I adopted to stop having this damn noise is as follows:
I configure my daw (ARDOUR with jackd) ==> sound card input = QU-24 and output = standard sound card of the daw.
For example: USB streaming recording with 10-n instruments with samples being read on the daw at the same time.
I don’t have the famous noise anymore.

If you have the noise problem on Window or MAC, then try my solution which is quite simple, if it is suitable for your use. But never read in USB …

But it is a pity that A&H does not correct its firmware, which annoys a lot of people, and given the price of this mixer.
nb: I tried on 3 different PCs, with differents USB2 ports, desactivated the sound cards in the bios, bought a high-end USB cable,etc, it doesn’t change anything 🙂

So if I understand it correct: You route the multitrack instrument channels of the QU console via usb to the DAW and the output of the DAW via the normal sound card of the PC back to the mixer (then probably with a jack cable?). So the way to the mixer via USB and the way back via the jack cable? I didn’t find a possibility to set different sound cards for the input and output of the DAW in Cubase Pro, which I am using…

You route the multitrack instrument channels of the QU console via usb to the DAW ==> yes
output of the DAW then probably with a jack cable? ==> yes (mix USB/Jack)

I don’t use cubase but ARDOUR (it works on windows, mac and LINUX). according to some research it seems that 2 soundcard does not work with cubase, to check…

Ardour… I googeled a little bit… very interesting! Seems to be free and seems to have everything, you need for multitrack-recording and playback… so perhaps I will test it. I could not find so much, for me relevant, differences to Cubase Pro.
I need:
Subsequent processing with EQ, reverb, compressor, delay and all this things, changing volume of each track in the mix (perhaps with automatation for solo parts etc.) and above all also transpose and speed change without change of pitch and last but not least export to mp3 … If I got it right, then Ardour has all these features? Plus different “soundcards” for input and output, which is better than Cubase and should sovle the digital noise problem, when playing back music to the A&H… 🙂

One correction after reading more: Ardour is not free by paying, but you have different payment-opportunities and I think the price is quite fair…

If you download the source code it is free…

[FrankParticipant]

Sorry, don’t know how to work with “source code”… how do I get the program out of the code? Or is it to complicated for a non PC specialist?

[SteffenRParticipant]

for Linux it’s easy, that’s the main platform for Ardour

[FrankParticipant]

Hmmmm, I am using windows… so it is more complicated there?

Yes windoze is harder than a linux distro. I suggest ubuntu as a good choice.
It also has a lot of other problems that will bite you when you are not expecting them to hit.

they said:Source Code (download icon note)
You’ll need to build this yourself. That can be a challenging and complex process, especially on Windows and macOS. We don’t provide help for this process, and we can’t support the end result. But if you’re hoping to modify Ardour or get involved in our development process, this is where to start.

Its licensed as GPL2. I see no mention of any cost at the download site.
follow the links and answer the questions to get the right linux version

There are the cost’s

But this is manageable :-), from 1$ each month subscribing to single amout for one version, you can choose…

Hello,
Ardour 5 is free and downloadable on every store apple, win or linux. The V6 requires donating to ardour.org or compiling the sources if you are familiar 🙂
indeed, for a few $ you can get the V6. In addition ardour has a very great wealth of plugins (a hundred for reverb, comp, gate, vocoder, phaser etc etc. Including VST plugins …
For music, being under linux (ubuntu) with ardour is the best thing because you can record with latency = 0 + OS strength
ardour works with JACKD which allows to route anything anywhere
But nothing prevents to try under win$

And then ARDOR allows me to bypass the horrible USB reading bug of A&H 🙂

Ardour is free per the download site I noted.
You do not need the latest version where you have to pay a little bit to have it.

And ubuntu costs a lot less than windoze10

[patkedParticipant]

for sure
I recommend Kubuntu 20.04 (instead of Ubuntu). consumes only 600 MB of memory and is very user-friendly and configurable
On the other hand, there is also UBUNTU STUDIO which is dedicated to music.
To have formidable performance, you can also use the real-time kernel either from UBUNTU or from Kubuntu or from Ubuntu Studio.
But using the standard kernel you will have good performance anyway and much better than Win $

Just wondering if there is an update on this issue. I still get it randomly.

For me, what fixes it is changing the buffer size in the control panel to something else, then back to what it was. i.e. I go from 128 to 256, then 256 back to 128, and it works again. It seems any change resetting the device fixes. Even selecting ‘safe mode’ or unselecting it, brings it back to normal.

I tried disabling uhci in bios but it didn’t do anything. Also tried different USB ports.
