I updated to the latest UC some time ago. Today, when I launched it, it didn't see my Quantum. The Quantum did work fine in Studio One, except the Quantum audio controls didn't show in S1.

I rolled back to the previous version (3.5.0.64605), and all was well. So, once again I upgraded to the latest, and not only did UC not see the Quantum, but it no longer worked in Studio One or as a Window audio device.

Rolled back, and I'm OK.

Now, I'm pretty sure that UC worked when I did the upgrade initially, but cannot guarantee that.

FWIW, my Quantum firmware is 1.1-22.

Any ideas?

If your device fails to show after an update, do the following steps:

1. Unplug device.
2. Uninstall UC, reboot
3. Re-install latest version, reboot after.
4. After boot, plug in device.
4a. On PC, some TB devices need another reboot after hot plug to initialize (device on).

Try that.

Hi,

I also noticed that in Windows 10, the latest Thunderbolt drivers are not compatatble with the Quantum (1 and 2). I was getting static noise and crackles in windows sound and in S1. I tried all version of UC and even back graded the quantum Firewares...

What i found that the older version 16 and 17 intel Thunderbolt drivers worked but the later DCH 1.41 series didn't work... took ages to fault find this.. but i'm happy the older drivers work and windows hasn't tried to force the new drivers on me just yet.

I still have the random pops and CPU spike problems, but that is limited to my Acer and it's CPU.. work around there is to use Throttlestop and turn of speedstep and cpu turbo and lock the clock speed to their maximum non turbo speed (34Ghz in this case)... this seems to work for the most part... but since i've updated to a newer Asus laptop aslo with Thunderbolt, this problems does not persist.

Bottom line is. With the Quantums being older tek now, it's worth experimenting with driver and Universal control versions, to find the best combination that works for you. I wouldn't update UC just because a newer version is realised.

I'm using the latest TB3 drivers with no issues on my PC. I think you have a motherboard issue. Your TB3 chipset probably needs a firmware update to support the latest Intel drivers. Doing a quick google search of that laptop shows that Acer has not updated anything since 2017, which is likely why. It's an Alpine Ridge based chipset which has been replaced by Titan Ridge and now Maple Ridge (Thunderbolt 4).

Laptops go outdated quickly. :)

Well, something similar on my side. Mojave and latest UC/Firmware.

When I’ve done the update back in September, I noticed that I had to reboot as the Quantum 2626 wasn’t seen. It was available as an audio device but UC lost it. After a reboot, it was there… phew!

No big deal as I thought it was just a glitch… until yesterday when I noticed that after sleep, UC was not seeing the 2626 except after a reboot, again. Repeatable behavior. I didn’t noticed it prior because I haven’t used my DAW a lot in the last month.

My solution for now: back to older Universal Control and obviously, firmware 1.3.91. It now behaves fine and it’s always back after sleep.
