Title:
  [USB-Audio - PX USB, playback] snd-usb-audio: probe of 2-3:1.0 failed
  with error -22 after kernel upgrade

Status in alsa-driver package in Ubuntu:
  New
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Bug report has been generated on a partially working configuration.
  That allows ubuntu-bug to do more work.

  USB-Audio Connection on Bowers & Wilkens PX Bluetooth Headphones
  started working when upgrading kernel from 4.13 to 4.15 series. Then
  it suddenly stopped working again on newer kernels. The bug report has
  been generated on the latest working mainline kernel 4.15.7. All newer
  kernels have some usb quirks in place, which should fix the playback
  sample rates to 48 kHz. The quirk seems not to be working correctly
  and hinder the audio system to recognize the USB-device as a sound
  device.

  The Headphones work on kernels before 4,15.7 when manually configuring
  pulseaudio to a default samplerate of 48 kHz.

  PX Headphones are on the newest firmware level.
