USB headset produces a periodic tick every second on Linux
Hi, I have a problem with my USB headset on Linux.
It produces a tick/pop/electrical-discharge-like sound approximately once every second whenever audio is playing.
I've reproduced it on Arch with the regular, LTS, RT and Zen kernels, as well as on Fedora, CachyOS and Ubuntu LTS, so it does not appear to be specific to my installed Arch setup or kernel.
The same headset does **not** produce the periodic tick when used with native Windows on the same hardware and also on another laptop. I also tested Windows in a VirtualBox VM with USB passthrough, and the tick occurs there too, so the Windows test only works when Windows has direct/native access to the USB device.
I've already tested this directly through ALSA (`speaker-test -D hw:2,0 -c 2 -r 48000 -F S16_LE -t sine -f 1000`), rather than only through PipeWire, and the behavior remains.
I'm trying to determine whether this is a Linux USB/audio driver issue, or something else.

Is this problem unique to one machine/device combination, or is the device broken on other machines or other USB devices broken on this machine?

this device is broken on other machines that have linux, but it works fine if they are running windows, other devices work fine on my PC

Re: USB headset produces a periodic tick every second on Linux
Try to set 'implicit_fb=1' parameter for snd_usb_audio module (Kernel_module#Setting_module_options).

Re: USB headset produces a periodic tick every second on Linux
whether this is a Linux USB/audio driver issue
Windows in a VirtualBox VM with USB passthrough, and the tick occurs there too
whether this is a Linux USB/audio driver issue
Any chance it's actually every other second?
https://wiki.archlinux.org/title/Power_ … utosuspend
Edit: still try dimich's suggestion - that "passthrough" is likely not exactly OVMF…

Re: USB headset produces a periodic tick every second on Linux
Try to set 'implicit_fb=1' parameter for snd_usb_audio module (Kernel_module#Setting_module_options).
Tried it. After a reboot, /sys/module/snd_usb_audio/parameters/implicit_fb shows Y for the card slots (including the headset's), so it was applied. No change, the tick is the same.
Any chance it's actually every other second?
https://wiki.archlinux.org/title/Power_ … utosuspend
No, I timed it and it's a steady ~1 second interval. I also ruled out autosuspend anyway:
- power/control for the headset was already "on" and runtime_status "active"
- I added a udev rule setting power/autosuspend=-1 for 0c76:1720 and rebooted, same tick
- I also booted with usbcore.autosuspend=-1 system-wide:
MmdrzaArch% cat /proc/cmdline
cat /sys/module/usbcore/parameters/autosuspend
BOOT_IMAGE=/vmlinuz-7.3.0-rc4 root=UUID=4c4a57d6-60cf-4f5e-80bd-b1ebbb8c215a rw loglevel=3 quiet usbcore.autosuspend=-1
-1Note: this boot was on 7.3.0-rc4, so the tick is also present on that kernel, not just 7.2.6.
Still no change with autosuspend off
Fair point about the VirtualBox passthrough, the host kernel still handles the USB controller there, so I'll drop that as evidence. The native Windows test on the same hardware, and on a second laptop, is the reliable comparison.
Also ruled out: unbinding the headset's HID interface, unplugging every other USB device, trying every port. Nothing appears in dmesg during the ticks.
I've also filed this on the kernel Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=222050

What about unbinding the device at large or testing in the pre-boot system?
Ie. is there an analog artifact that relies on the driver to suppress it?

Re: USB headset produces a periodic tick every second on Linux

Tried unbinding the whole device (echo '1-1.2' | sudo tee /sys/bus/usb/drivers/usb/unbind), so no driver is attached, and listened with the headphones on and the volume up: complete silence, no tick and no periodic noise. So it's not an analog artifact at idle. The tick only appears while an audio stream is playing.
During boot, I hear a few one-off pops that sound like power-on transients, but nothing periodic. In the BIOS menu itself it is completely silent. So this doesn't look related to the tick.

Re: USB headset produces a periodic tick every second on Linux
Any usbish errors in dmesg/the journal? FWIW an additional arcane module option to try is disabling the low_latency support
sudo modprobe -r snd_usb_audio && sudo modprobe snd_usb_audio low_latency=0but if that would help it's weird that a Windows VM reproduces this, assuming you properly did the passthrough so the device wasn't taken by the kernel driver

Re: USB headset produces a periodic tick every second on Linux

No. I ran `sudo dmesg -W` (and `journalctl -kf`) while playing audio through the headset for about 5 minutes, with the tick audible. Nothing new was logged after the headset's normal enumeration at boot: no urb errors, disconnects, resets or re-enumeration. I can post the full boot log if it would help.
FWIW an additional arcane module option to try is disabling the low_latency support
lowlatency=0: /sys/module/snd_usb_audio/parameters/lowlatency reads N after reboot, so it applied. Same tick.
but if that would help it's weird that a Windows VM reproduces this, assuming you properly did the passthrough so the device wasn't taken by the kernel driver
I attached the headset with a VirtualBox USB filter. Windows sees the real USBFH11, and the headset no longer appears among Linux's output devices, it still ticked in the VM though.

"when attaching the device" might also be interesting - but that tick is periodically on the second.

Re: USB headset produces a periodic tick every second on Linux

I can clearly hear 1 second ticks in sine wave but not in "normal music" and video.
By the way, intervals between ticks are roughly, in samples: 48730, 49200, 49200, 50630, 47440, 49680, 49010, 50070, 47950. So it's not exactly one second, at least not in DAC's frame of reference. Looks more like programmatical delay.
What does the headset actually look like? Does it have pluggable jack sockets? Mic or headphones autodetection artifact comes to my mind.

Re: USB headset produces a periodic tick every second on Linux

Not hearing the ticks in the video is expected as I mentioned it's not present when capturing the screen and audio using OBS studio, but the other two sound files were recorded with the headphone's own mic from the sound it was outputting, so you can hear the tick ( it is less noticable in music but I can still hear it, maybe your volume is a bit low? )

It doesn't have pluggable jack sockets, the headphone itself is a SONA T-RGH304, you can see it here:

Re: USB headset produces a periodic tick every second on Linux
https://drive.google.com/file/d/1sILpFF … gVRPp/view doesn't maybe lend itself to expose the artifact because of the "music"…
Can you hear it when muting the mic ?
Do you get it w/ playback from the multi-user.target (2nd link below, don't start any GUI to rule out -most- services polling devices)

Are there any external docks or hubs involved?

Yeah followed your link and went into TTY after a reboot, also muted my mic there too, the ticking is still present when playing the sine

Nope all devices are connected directly to motherboard/front ports ( the headphone is connected to the motherboard port, but i also tested every other port with it )

Re: USB headset produces a periodic tick every second on Linux
it is less noticable in music but I can still hear it, maybe your volume is a bit low?
Yes, now I can hear it, espessially after applying high-pass filter. However, it doesn't seem as regular as in sine wave. For example, I see two distinct clicks spaced by 547 ms (26270 samples) at the end of the file, followed by another click in 70 ms.
Maybe clicks are somehow related to RGB illumination? Does LEDs behavior differ in linux and windows?
Can you check what HID subdevices the headset registers and what drivers are used for them?

they're always on, same colors, same behavior even on my phone or with the PC powered off

Here's what the headset registers, straight from the system:
lsusb -t (headset is Dev 003 / If 0–3):
|__ Port 002: Dev 003, If 0, Class=Audio, Driver=snd-usb-audio, 12M
|__ Port 002: Dev 003, If 1, Class=Audio, Driver=snd-usb-audio, 12M
|__ Port 002: Dev 003, If 2, Class=Audio, Driver=snd-usb-audio, 12M
|__ Port 002: Dev 003, If 3, Class=Human Interface Device, Driver=usbhid, 12M/proc/bus/input/devices (only entry matching the headset):
I: Bus=0003 Vendor=0c76 Product=1720 Version=0100
N: Name="Solid State System Co.,Ltd. USBFH11"
P: Phys=usb-0000:00:1d.0-1.2/input3
S: Sysfs=/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2/1-1.2:1.3/0003:0C76:1720.0001/input/input2
U: Uniq=
H: Handlers=kbd event2
B: PROP=0
B: EV=13
B: KEY=7800000000 e000000000000 0
B: MSC=10hidraw mapping (only entry matching 0c76:1720):
== /sys/class/hidraw/hidraw0 ==
KERNEL=="hidraw0"
KERNELS=="0003:0C76:1720.0001"
KERNELS=="1-1.2:1.3"
KERNELS=="1-1.2"
ATTRS{idProduct}=="1720"That's every HID-related entry the system has for this device — of its 4 interfaces, only one (If 3) is HID, and it creates exactly one input node and one hidraw node, nothing more.
And the per-interface driver bindings for the headset (0c76:1720, all four of its interfaces):
/sys/bus/usb/devices/1-1.2:1.0 -> snd-usb-audio
/sys/bus/usb/devices/1-1.2:1.1 -> snd-usb-audio
/sys/bus/usb/devices/1-1.2:1.2 -> snd-usb-audio
/sys/bus/usb/devices/1-1.2:1.3 -> usbhidLast edited by Mmdrza (Today 16:51:48)

Re: USB headset produces a periodic tick every second on Linux
From your kernel big
Host controller is EHCI only (ASRock H61M-VG3 chipset has no xHCI). Historical kernel bugs (e.g. bugzilla #6709, #9230) describe a similar class of periodic clicking on USB audio devices tied to isochronous transfer scheduling/timing under EHCI, and a 2013 kernel commit note describes the EHCI periodic scheduler's split-transaction handling as fragile enough that a fix for one bug there previously caused audible playback regressions on other devices. I'm not asserting this is the same root cause — just flagging it as a possibly related historical pattern in case it's useful context.
Do you have access to an xhci system that you could test this on?
