I’ve scoured the internet for a solution but have come up empty. Im on Fedora 42 Workstation on a Dell Latitude 7420. I use a portable Fosi DS2 usb dac for my IEM’s. My problem is that when using the dac the sound cuts out or stutters every minute almost like clockwork. IIf I plug the headphones directly into the 3,5mm audio jack on the laptop it sounds fine. I suspect it might have something to do with the usb port but I just don’t know anymore and I’m reaching out for help.
Could it be that power management is cutting power to the USB port?
Thank you for the suggestion. I feel like you might be right. Unfortunately I’m getting this …
bash: /etc/udev/rules.d/50-usb-power-always-on.rules: No such file or directory
You’d need to create that file. It would define a custom rule to disable USB power management.
To undo the change, just remove the file.
Also, You’ll need to run sudo udevadm trigger to trigger a re-evaluation of the rules (or reboot).
Ok, done, but unfortunately its still cuts out =(
It’s time to dig though the log messages then to figure out what is really going on. 
Try leaving sudo journalctl -f running in a terminal window and watch for error messages around the time the problem occurs.

Ok, so. I tried listening to some music on youtube and there were no problems. It works fine! I then started up Spotify which is what I primarily use for music listening and I get the following below.

It looks like there might be a solution posted here:
I fixed the crash and dump issue with Spotify using the link you provided. I’m still having the audio hiccup problem. I also seem to have celebrated too soon regarding audio through Youtube. After an extended listening session, I heard it again.
journalctl looks clean. I don’t see any errors when the hiccups occur.
Thank you for all your help. I’ll just stick to the onboard audio for now I suppose. I might just go back to Linux Mint
