USB sound keeps cutting out

[hotmitts]

I have the Behringer UMc404HD 'U-Phoria' which connects via USB

I know people hate on behringer by the way, but this has been working great for years.

Now suddenly everytime I plug in another USB device (external drive, game controller) the sound drops out. Unplug something and it's back.

I tried everything on this list:

I don't think it's the sound device, i think it's windows [or my PC) deciding to cut it. The sound device has it's own power so it's not a power issue, even though I tried changing power options for the USB device behaviour.

Anybody else have this?

I just got a hunch it's a recent thing to do with windows or my PC but it was all working fine for years and now this all of a sudden

Please describe how you connect all the devices, hubs etc and what mainboard you have. And what those other devices are.

One question is whether the other devices have power on their own.

It's an ASUS board, I'll have to double check the model, nothing unusual, and I've tried plugging in to board, or case ports, or powered USB hub. Different combinations and just ordinary USB devices like game controller, external storage drive....always the same.

But only started happening recently. Weird.

- Make sure the motherboard BIOS is updated and clear the CMOS.


- It is AMD motherboard? Make sure to use the latest chipset driver
https://www.techpowerup.com/download/am ... t-drivers/

- Disable Windows Hibernate
https://www.elevenforum.com/t/enable-or ... s-11.1894/

- Make sure:
USB selective suspend setting = Disabled
PCI Express Link State Power Management = OFF


- Make sure USB polling rate is not higher than 500Hz, the default is 125Hz.
Razer/Logitech/Steels series/etc mouse/game controller utilities may change the default polling rate.

- Try a different USB port.

- Try with a different USB cable.

- In the BIOS set C-states disabled

- IF the motherboard is from ASUS, you should uninstall ALL the harmful ASUS bloatware
like MyASUS, ASUS System Control Interface v3, Armoury Crate Control Interface,
Armoury Crate & Aura Creator Installer.
In the BIOS press F7 and go to the:
Tool>ASUS Armory Crate>Download & Install Armory Crate app = Disabled
You do not need any ASUS bloatware to control the fans.


- If all fail, do a clean Windows installation from scratch.

And do some tweaks.

IF it still does not work, reseat(remove&plug again) all the PSU cables on *BOTH* ends
and reseat the CPU. What is the CPU model?

Yes, most likely the change is Winblows updating the chipset drivers and overriding good ones with bad ones.

Thanks for the suggestions, trying everything

Wait, isn't it a known problem that Windows update has bad AMD chipset drivers for a while now? I seem to recall.

Check if you/your pc recently installed the 24H2 update. Theoretically they fixed the known USB connection issues but you never know.

Yes!
I encountered this problem around early 2023, where my Linux distro upped the polling rate for a more or less USB3 world. Meanwhile my server board and CPU are ~2013 tech, with USB3 as a once newish feature ... Basically, my RME UFX--which had worked great up until--started having bizarre, inconsistent underrun issues, out of nowhere. Then I noticed my BT stuff (also USB), plus mouse/keyboard began to stall/disconnect in a similar way .....

The fix (Arch Linux):
Testing

Code: Select all

sudo modprobe usbhid poll=8

1 → 1000 Hz (1 ms)
2 → 500 Hz (2 ms)
4 → 250 Hz (4 ms)
8 → 125 Hz (8 ms)

Persistent

Code: Select all

echo "options usbhid mousepoll=8" | sudo tee /etc/modprobe.d/usbhid.conf

You can use udev for finer control.

Other observations:
The RME UFX is a UBS 2.0 device and regardless of what port it's plugged into (USB2/3), the problem occurs if the polling rate is not addressed. Which I don't quite understand yet.
Meanwhile, a USB3 audio device, like the RME Babyface Pro worked all along.

Which is why my instinct at the time was, it must be failing hardware--either the USB2 controller on the board, or the UFX. After all, it's a build that's going on nine years old, and my UFX is roughly the same age ... Nope, low and behold it was the polling rate of usbhid which crept up/caught up.
Amazing

Thank you for reporting!
USB 1.1/2.0 Low Speed is 125Hz
USB 2.0 High Speed mode is up to 8000Hz

Higher USB pooling rate was known to create problems until Microsoft fixed in the
Windows 11 build 22621.1926

It's not 100% perfect yet and we can still have issues today, maybe faulty drivers.

Did you solve the problem?

It's better, thanks, the USB does cut out briefly sometimes but overall much better.
I tried several things at once but I reinstalled the chipset drivers which may have been the clincher
