I just bought a UMC404HD. I did some research before buying to make sure it was well supported under linux. Most posts say its working great. So i've plugged mine in expecting things to just work but that has not been the case.
I plugged it all in and found that it stutters every second like a scratched cd would. I've played around with the sample rate and settings but have not been able to fix it.
- There are no Xruns.
- There are not error entries in syslog or jack log.
- The CPU is running around 5% and does not spike
- I'm dual booting and this device works flawlessly in windows. I've also tried on MacOS Monterey and also works fine.
- Tried different USB cables
- I've tried standard and low-latency kernels (5.4.0-107-lowlatency)
- I'm running Mint 20.03 but have also tried Ubuntu LTS 20.04 and Ubuntu Studio.
Here is some information on the device:

Has anyone seen something similar? Am I in the correct forum? Is there any further information I should provide?
Thanks!
