Package: src:linux
Version: 6.12.30-1~bpo12+1
Severity: normal
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.

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

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.

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 access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 20 rate: 48000 (48000/1) period_size: 128 buffer_size: 32768 $ cat /proc/asound/USB/pcm0p/sub0/sw_params tstamp_mode: ENABLE period_step: 1 avail_min: 32640 start_threshold: 9223372036854775807 stop_threshold: 32768 silence_threshold: 0 silence_size: 0 boundary: 4611686018427387904 > > The additional IRQs listed under the 6.12 kernel don't appear to > > exist, only irq/155-xhci_hcd in this case. > > They exist and have been allocated but are not used.

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) > [...] > 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? I've removed all nvidia* packages but the problem still remains after 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 -

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 0000000 136705 146445 104226 000714 065106 122636 025711 113316 0000016 030251 142732 153350 046337 135743 007723 167576 052533 0000032 020014 064122 155565 000156 052467 105312 043434 142123 0000048 051052 142223 035427 154113 163333 154443 052143 127476 0000064 I can't reproduce this in 6.1.

One workaround is to disable TPM in the BIOS. Without /dev/hwrng and the
hwrng process there is no more periodic glitching.
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.
