Hi there, On my T480s on Archlinux I often have issues with my USB microphone (h1 handy recorder): Sep 14 19:00:57 t480s kernel: retire_capture_urb: 2477 callbacks suppressed Sep 14 19:01:02 t480s kernel: retire_capture_urb: 2480 callbacks suppressed Sep 14 19:01:07 t480s kernel: retire_capture_urb: 2479 callbacks suppressed Resulting in just noise / garbage when recording with an ffmpeg/pulseaudio based script: https://github.com/kaihendry/recordmydesktop2.0/blob/master/x11capture https://s.natalian.org/2018-09-14/noise.mp4 It's difficult to reproduce, but I have managed to experience the issue again and again on stable kernels, e.g. Linux t480s 4.18.6-arch1-1-ARCH #1 SMP PREEMPT Wed Sep 5 11:54:09 UTC 2018 x86_64 GNU/Linux But not (yet) upon linux-lts 4.14.69-1 aka "LTS". Any tips how I should proceed here? https://www.kernel.org/doc/linux/REPORTING-BUGS is a bit overwhelming.
