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.
