Description gizmo 2015-11-15 21:50:21 EST
Description of problem:
When playing audio through the Jabra Evolve 65 UC headset using either the USB cable or the Jabra Link 360 USB dongle, sound is played back too fast, with a 'chipmunk' effect.  I don't know if the recording side is affected or not, but people have not commented on it if it is.

Version-Release number of selected component (if applicable):
Name        : pulseaudio
Arch        : x86_64
Epoch       : 0
Version     : 6.0
Release     : 8.fc22
Size        : 3.3 M
Repo        : @System

Name        : alsa-plugins-pulseaudio
Arch        : i686
Epoch       : 0
Version     : 1.0.29
Release     : 1.fc22
Size        : 101 k
Repo        : @System

How reproducible:

Steps to Reproduce:
1. Plug in headset using USB cable.
2. Play audio

Actual results:
Audio plays fast.  Buffered audio streams (like youtube) play without gaps, but realtime streams (like Skype, or Jabber) play with gaps.

Expected results:
Audio should play back at the normal rate with no gaps.

Additional info:
My Logitech USB headset plays just fine.

When using the Jabra headset in BlueTooth mode, audio playback is normal using either the A2DP audio profile or the HSP/HFP.

When connected with the USB cable lsusb reports the Jabra device as:
Bus 001 Device 008: ID 0b0e:030b GN Netcom

The Jabra device plays just fine on Windows, using the same computer.

System is running KDE with Phonon GStreamer and alsa.

I honestly don't know if this is a Pulse problem or an ALSA problem.

This bug has been open now for 2 months with zero movement.  Is there anything I can do to help out here?  I'm willing to troubleshoot, I just have no idea what to do next.
Comment 2 Wim Taymans 2016-01-29 13:50:29 EST
I'm pretty sure that this is an alsa problem. The driver probably configures the wrong samplerate or maybe it needs a tweak for this particular hardware.
Comment 3 joerg.pareigis 2016-02-15 12:11:38 EST
Exactly the same here.
Trying with newest version of Debian 8 and SuSE 42.1.

The headset plays too fast with a short gap every second. Regardless which connection is used. Directly via USB-Cable, or via BT-Dongle. Both with the same result.

It plays the correct speed when connected via Bluetooth to Android devices.
Connected at Windows PC it pays also without any spot.

Ok, so I've got the same question; what can I do to help troubleshoot this?  Guys, I'm willing to be your eyes and hands here, but these eyes and hands need a brain to direct them. :)

Hi. I've had the same problem.
Here is workaround that helped me:

In file


;default-sample-rate = 44100


default-sample-rate = 48000

And then reload pulseaudio

pulseaudio -k

Just tried this, and it appears to work here as well.
