    Installed 1.95 a few days ago. Made a small difference, but I must emphasize small. I switched from the USB 3 to USB 2 interface. Still little change. There is change, but only a little. I’m using the QU24 as my system audio interface and the streaming noise occurs in any program that sends audio to the QU. ProTools, YouTube, Windows media etc. doesn’t matter. I’ve set all power management to never or to 100%. For Me it seems only to happen to the playback stream, however I do little in house recording. Most is done live at gigs, then imported and mixed down. Does anyone have any information as to whether switching to TC/IP would eliminate the problem, meaning it only happens with USB, and continue to use MIDI for the control if possible? Just thinking out loud.

    After some more testing i’ve noticed the same behaviour like Joeschmo. The distortion only occures on the playback stream. The recorded media is not distorted.

    Now i got this error even when disabling XHCI via BIOS on my MSI…. At least this had worked until v1.95 ..

    Is there any further information on the state of the problem? The firmware update doesn’t look like it’s fixed the problem, only minimised it. This is an issue for our SQ6. Attached an mp3 of the sounds we are getting when recording via USB-B to a MacBook Pro.

    Hooray!

    1.95 seems to have completely fixed the issue for me.

    I’m running Ubuntu 16.04.4 LTS on an Intel 4790-K, USB3.

    I’m mapping the USB sources via GStreamer as described Here and connecting into OBS Studio as described here

    Great to hear. Any word on a SQ firmware update for those of us suffering the same problem on an SQ mixer?

    My problem is when connecting my portable LaCie drive to the Qu-Drive usb, I have a digital noise in the LR master, but only on the Left. This is when the LaCie is being read only at first connection.
    Qu-16 with V1.95

    Just found that the noise is from ST3, pull down ST3 fader and the noise in main LR on the Left CH stops

    I didn’t have the problem with Qu-Pac 1.94 – Rev 4557. Then I upgraded to 1.95 – Rev 4561 and the problem started.

    Every couple of minutes the weird distortion occurs for a couple of seconds, very repeatable. I used the QU-PAC to record the signal from my speakers while playing a piece.

    I tried re-booting the computer, hard-resetting the Qu-Pac, unplugging everything etc. didn’t help. I did a firmware-downgrade to 1.94 – Rev 4557 and now the problem is gone.

    I put my information here instead of the Google doc, and I’ll happily answer more questions about my setup or try stuff.

    Mixer: Qu-Pac
    Computer: Laptop, Debian testing, kernel 4.17.0-3-amd64 #1 SMP Debian 4.17.17-1 (2018-08-18) x86_64 GNU/Linux
    Processor: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz
    USB-B is connected to the laptop directly, the only other external USB device is the mouse.
    It’s connected to a USB-3.0 port since all 4 ports are USB-3.0
    Buffer setting: I start jack like this: jackd -r -dalsa -dhw:2 -r48000 -p1024 -n3 -i32 -o32 (no realtime, 1024 samples buffer size). I also tested 256 as buffer size, no difference.
    The noise occurs during playback, I didn’t test what happens if I use a known-sane audio source for recording.
    Power Management: I’m not sure. When I leave the laptop alone long enough the screen does turn off but that’s far longer than the couple of minutes before the distortion occurs.
    Wifi: There is a built-in Wifi but I wasn’t using it (ifconfig wlp3s0 down)
    Other USB devices: The built-in video camera and bluetooth use the internal USB, output of “lsusb -t”:
    /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 5000M

    Update: The problem also occurs with firmware 1.94 – Rev 4557 but it’s _very_ rare and unpredictable (~once a day)

    I haven’t fully tested it yet but it seems I have eliminated the problem by buying a USB2 hub and dumping lots of devices onto that instead. All that goes into my motherboard now is mouse, keyboard, SQ and HUB. I used to get the problem every time I moved my mouse!

    What’s weird is, I thought I’d tried removing all ‘unwanted’ devices as part of my original troubleshooting process with no success. Maybe it is now something to do with me spreading devices across different USB controllers.

    Something worth trying if you haven’t already, even if it is stating the obvious, remove all unwanted devices for now, but spread them across ports far away from each other and try different combinations

    I’m experiencing the identical problem as junior with my SQ5. The recorded audio is distorted and garbled using both Reaper and Tracktion software.

    I’m also using a MacBook. Adjusting the buffer size does not make any difference with either software.

    I’ll update to firmware version 1.3.0 later today and see if there is any improvement.

    Here’s a sample of the unprocessed audio. The first set recorded just fine. The second and third sets were distorted and garbled.

    No changes were made … I simply paused the recording during the break between sets.

    So guys, tonight I recordered a whole live without distortion with my SQ5, using Tracks Live, my laptop is a T410 with a 120GB SSD, I’ve mapped in the I/O “Outputs/Mix Out/MAIN L-> channel 1, MAIL R-> channel 2” of the USB B source.

    2 hours and perfect recording.

    Yeah, I always told… Never problems with an Lenovo Thinkpad T410. This machine only has USB 2.0 ports… so no problems… I use it since one year and never had a problem since this time. I bought it used from eBay, pimped it up with SSD and a clean Win 7 installation, just for this purpose, beacause the brandnew expensive Lenovo Ideapad with 16 GB Ram, SSD also and i5 core, especially bought for this purpose before, alwas had this problem (only USB 3 ports!). I hope, my good old T410 will live as long as my A&H QU16. I fear, A&H will not get a better solution, beacause already they are working so long time on it now and couldn’t fix it for everybody… :-(. But hope dies last 🙂
