Sorry for the delay. I'm involved in hundreds of different bugs and lose track...
I suggest the next step is to reproduce the problem with 18.04 and see if similar errors appear in your journal (run 'journalctl'): Oct 21 17:23:33 hostname pulseaudio[1288]: [alsa-sink-USB Audio] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write. Oct 21 17:23:33 hostname pulseaudio[1288]: [alsa-sink-USB Audio] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers. Oct 21 17:23:33 hostname pulseaudio[1288]: [alsa-sink-USB Audio] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. Alternatively, don't change Ubuntu version at all, and just try the latest kernels: http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D Essentially we want to know: (1) Was there an older kernel where it ever did work? (2) Is the bug still there in the latest kernels? If not, then exactly what version fixed it? (3) Otherwise, does the bug always occur when those error messages above appear? ** Changed in: linux (Ubuntu) Status: Expired => Incomplete ** Changed in: pulseaudio (Ubuntu) Status: Expired => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1725863 Title: Logitech G930 drops connection and reconnects in 17.10 (But not in 17.04) Status in linux package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: Incomplete Bug description: Every so many seconds / minutes the Wireless headset Logitech G930 simply drops connection. It always reconnects but when doing a recording, a meeting, listening to music or a movie it simply drops the connection for 1 to 3 second. This happens several times an hour. If it helps, it was not happening in 17.04 (Never happened in more than 200+ hours of using the headset).
