[Yann Marchand]

Since upgrade Ubuntu 16.04 to 18.04, my bluetooth did not work fine, sound is disjoined

1) Ubuntu 18.04.1 LTS

2) apt-cache policy pkgname
N: Impossible de trouver le paquet pkgname

3) With Ubuntu 16.04, my headset ( Bose QC35 ) was working fine by bluetooth connection

4) Sound is disjoined with Ubuntu 18.04

[Daniel van Vugt (vanvugt)]

Can you please explain in different words what you mean by disjoined sound?

I am also wondering if this might be somehow related to bug 1553669 or bug 1620636.

[Yann Marchand (yann66)]

Hi Daniel,
Thanks for your answer, sorry for my poor english
No relation with bug 1553669 or bug 1620636.

I can pair my Bose QC35 with Ubuntu 18.04, but the sound is "jerky" ( untimely cut few sec with sound and few seconds without sound ).
It was not the case with Ubuntu 16.04, only since the Ubuntu 18.04 upgrade.

[Daniel van Vugt (vanvugt)]

Wow, OK. That is indeed disjoint/disjoined.

[Daniel van Vugt (vanvugt)]

Can you please run this command and send us the output?

  dpkg -s pulseaudio

[Daniel van Vugt (vanvugt)]

Also, I notice you seem to be using this Bluetooth adapter:

  Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Unfortunately we do find that brand (Cambridge Silicon Radio) of Bluetooth adapter to be unreliable and buggy. So please also try a different Bluetooth adapter.

[Yann Marchand (yann66)]

Thank's a lot Daniel, I will change my adapter ( if do you have any advice regarding this ).
For information, find hereafter : dpkg -s pulseaudio

Description: PulseAudio sound server
 PulseAudio, previously known as Polypaudio, is a sound server for POSIX and
 WIN32 systems. It is a drop in replacement for the ESD sound server with
 much better latency, mixing/re-sampling quality and overall architecture.
 .
 These are some of PulseAudio's features:
 .
   * High quality software mixing of multiple audio streams with support for
     more than one sink/source. May be used to combine multiple sound cards
     into one (with sample rate adjustment).
 .
   * Wide range of supported client libraries. ESD, ALSA, oss, libao and
     GStreamer client applications are supported as-is. Native PulseAudio
     plug-ins are also available for xmms and mplayer.
 .
   * Good low latency behaviour and very accurate latency measurement for
     playback and recording. Ability to fully synchronize multiple playback
     streams.
 .
   * Network transparency, allowing an application to play back or record
     audio on a different machine than the one it is running on.
 .
   * Extensible plug-in architecture with plug-ins for jackd, multicast-rtp
     lirc and avahi, just to name a few.
 .
 This package contains the daemon and basic module set.
