Dear Maintainer,

   * What led up to the situation?

Playing sound via a Focusrite Clarett 8Pre USB audio interface causes
a regular glitch in the sound every ~60 seconds, accompanied by the
kernel log message `retire_capture_urb: N callbacks suppressed'.

Occasional xruns are reported by pw-top, but not consistently with the
glitch/retire_capture_urb warning.

This only seems to happen with Linux 6.12* amd64 kernels.

1. Boot a backported Linux 6.12* kernel in bookworm.

Tested with:
- linux-image-6.12.12+bpo-amd64
- linux-image-6.12.30+bpo-amd64

2. Connect the USB interface and set as the default output device.

3. Play a sound.

Tested with:
- speaker-test -t sine -c 2
- mplayer -ao alsa|pulse|jack

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Ineffective:
- Disabling pipewire/wireplumber/pulseaudio
- Changing ALSA buffer-size and period-num
- With or without threadirqs
- rtprio settings look fine and audio threads are given the same
  priorities under all kernel versions
- Using the same USB interface with a different laptop running trixie
  (linux-image-6.12.33+deb13-amd64)

Effective (this laptop):
- Playing sound through internal audio hardware (6.1 and 6.12
  kernels)
- Playing sound through the same USB interface when running a stable
  bookworm 6.1 kernel (e.g. linux-image-6.1.0-37-amd64).

   * What was the outcome of this action?

When running a Linux 6.12 kernel (backported in bookworm, or seemingly
also in trixie) playing sound in various ways through a USB audio
interface results in glitching and retire_capture_urb warnings.

   * What outcome did you expect instead?

I would expect the same behaviour as observed with Linux 6.1 kernels.

   * Further info

There are no differences in default ALSA parameters running under 6.1
or 6.12 kernels.

Diff between udevadm reported device info under 6.1 and 6.12 kernels.

The additional IRQs listed under the 6.12 kernel don't appear to
exist, only irq/155-xhci_hcd in this case.

You mean "hw_params", right?

But these are for the capture side (pcm0c), whereas I thought the
problem was with playback (pcm0p)?

[...]

They exist and have been allocated but are not used.  The XHCI PCI
driver can currently allocate multiple IRQs but only installs an IRQ
handler for the first one.  This is a bit strange but should not cause a
problem because it also doesn't configure the hardware to use the
additional IRQs.

I see some reports that the Nvidia proprietary drivers can cause latency
spikes that affect audio.  Can you please test whether this problem
still occurs when using the nouveau driver instead?

Yes sorry, here is the correct info – also with the default number of
output channels (i.e. all: 10 analogue + 10 digital). The parameters
are otherwise the same after disabling digital I/O, and has no effect
on the glitching.

$ cat /proc/asound/USB/pcm0p/sub0/hw_params

  channels: 20

Thanks. The IRQ handler also behaves similarly under both 6.1 and 6.12
kernels so this doesn't seem to be an issue.

- CPU utilisation: ~10% (top)
- IRQ rate: ~3.4 kHz (derived from: watch -n 10 -d cat /proc/interrupts)
switching to nouveau.

I also tried the following to no avail:
- reverting all firmware packages to stable versions
- blacklisting nouveau (loading only i915 for the integrated GPU)
- disabling Thunderbolt 4 in the BIOS
- turning off WiFi and Bluetooth in the Gnome system menu

It seems like the periodic glitching is related to hw_random.

A glitch happens every time the hwrng process becomes active, every ~60
seconds, and can be reproduced on demand by reading 64 bytes.

  # od -Ad -N64 < /dev/hwrng

  0000064

I can't reproduce this in 6.1.

The kernel log for 6.1 includes "No test for fips(ansi_cprng)
(fips_ansi_cprng)", whereas 6.12 doesn't, but in either case fips is not
enabled.

  # cat /proc/sys/crypto/fips_enabled

I've upgraded to trixie and can confirm the glitching is still present
when TPM is enabled on this laptop.

I'm happy to keep TPM permanently disabled and close this bug report
unless there is anything further you would like me to test?

I also found a similar issue reported with AMD, which resulted in
disabling TPM RNG use for all AMD fTPMs.
