alsa-project/alsa-lib issue #284 was opened from Konfekt: Hello, `journalctl -p err` showed the message ``` pulseaudio[15806]: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers. ``` Hopefully this bug tracker reaches the ALSA developers? Here's more output: ```sh Nov 15 10:28:58 notebook bluetoothd[1340]: src/profile.c:ext_io_disconnected() Unable to get io data for Hands-Free Voice gateway: getpeername: Transport endpoint is not connected (107) Nov 15 10:28:58 notebook kernel: Bluetooth: hci0: SCO packet for unknown connection handle 6 Nov 15 10:28:58 notebook kernel: Bluetooth: hci0: SCO packet for unknown connection handle 6 Nov 15 10:28:48 notebook pulseaudio[15806]: mSBC decoding error (-2) Nov 15 10:14:35 notebook pulseaudio[15806]: Playback too far ahead (4591), drop source 1168 Nov 15 10:14:35 notebook pulseaudio[15806]: Doing resync Nov 15 10:12:28 notebook pulseaudio[15806]: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

In the hope that this error message gives a hint. Attached further alsa-infos.
