Re: [BUG] xHCI: AMD Strix Halo [1022:158b] isochronous full-duplex USB audio instability (frame active: -18)

Hello,

I enabled the requested dynamic debug:

echo 'func handle_tx_event +p' > /proc/dynamic_debug/control

The frame active: -18 line came from snd-usb-audio dynamic debug:

echo 'file sound/usb/pcm.c +p' > /sys/kernel/debug/dynamic_debug/control

specifically from the retire_capture_urb() debug print:

sound/usb/pcm.c:1336 [snd_usb_audio]retire_capture_urb =p "frame %d 
active: %d\n"

With handle_tx_event() debug enabled as requested, I reproduced the 
issue again.

Test setup for this run:

Machine: HP ZBook Ultra G1a
Platform: AMD Strix Halo / Ryzen AI Max
Controller: 0000:c5:00.4 AMD Strix Halo USB 3.1 xHCI [1022:158b]
USB path: usb7 / 7-1
Device: Audient iD14 MK1 [2708:0002]

Reproduction sequence:

physically disconnect and reconnect the USB audio interface
restart PipeWire

run jack_delay through pw-jack:

PIPEWIRE_QUANTUM=128/48000 PIPEWIRE_PROPS='{"node.lock-quantum"}' 
pw-jack jack_delay

The log now shows handle_tx_event() reporting missed-service events, 
followed by the snd-usb-audio frame active: -18 messages.

At 20:44:59 the same pattern repeated more strongly, followed by

[Sun Jun 21 20:44:59 2026] usb 7-1: 2:1 Stop Capture PCM

The iD14 path in this log uses a separate sync endpoint, not implicit 
feedback:

[Sun Jun 21 20:42:14 2026] usb 7-1: 1:1: found sync_ep=0x81, iface=1, 
alt=1, implicit_fb=0
[Sun Jun 21 20:42:14 2026] usb 7-1: Creating new data endpoint #1
[Sun Jun 21 20:42:14 2026] usb 7-1: Creating new sync endpoint #81
[Sun Jun 21 20:42:14 2026] usb 7-1: 1:2: found sync_ep=0x81, iface=1, 
alt=2, implicit_fb=0
[Sun Jun 21 20:42:14 2026] usb 7-1: Creating new data endpoint #82

During the same run, jack_delay showed a discrete round-trip latency 
change. It was quasi-stable around:

498.579 frames 10.387 ms

then reported:

??? 420.350 frames 8.757 ms
451.919 frames 9.415 ms
451.606 frames 9.408 ms

and later became quasi-stable again around:

493.579 frames 10.283 ms

So the user-visible symptom is a discrete latency-state change during 
continuous full-duplex streaming, while the kernel log shows xHCI 
missed-service events and subsequent snd-usb-audio -EXDEV frames.

Regarding the related thread you pointed me to:

https://lore.kernel.org/linux-usb/18b4e4f7089aa4f1.da8dbe994ae3bb77.445e21b98b0b205b@GordonMsi/

I checked my Strix Halo system against that LTC/LTR angle. I do not know 
whether it is the same root cause, but the error class looks similar: 
AMD client platform, USB audio isochronous traffic, xHCI missed-service 
/ -EXDEV.

For xHCI 0000:c5:00.4:

/sys/kernel/debug/usb/xhci/0000:c5:00.4/reg-cap:

HCCPARAMS1 = 0x0118ffc5

Bit 6 is set, so xHCI HCCPARAMS1.LTC = 1.

However, lspci -vvv for the same xHCI function reports:

DevCap2: ... LTR-
DevCtl2: ... LTR-

The upstream internal GPP bridge / root port 0000:00:08.3 also reports:

DevCap2: ... LTR-
DevCtl2: ... LTR-

So on this Strix Halo system, xHCI advertises LTC, but standard PCIe LTR 
is not exposed on either the xHCI function or the upstream bridge.

I do not know whether Set LTV would reach the AMD fabric through an 
internal sideband path on this integrated controller, or whether LTC is 
USB-link-scoped only here.
