QNAP audio "Jabra Link 380" interrupted or cracking

Submitted by themuk on #1

Hi,

I use a Logitech 930e webcam, USB audio card and a Jabra Link 380 with Jabra Evolve 2 75 headset on a QNAP TS253be with 16GB Ram.

All devices work great except the Jabra Link 380 as I have the idea when something else is taking some CPU resources the audio begins to stutter/Cracking.

Audio and vide from the webcam are ok and also the USB soundcard. I use the device in a Hyper-V image.

Is there something I can do to have less stutter/cracking audio in the Virtual Here server setiings or client? Or things I can change on the QNAP like CPU priority?

 

Thanks in advance.

Yes that is a tough one, I think the thing you could try is to turn down the jabra audio quality (i.e record at a lower frequency). That will probably stop the crackling but the audio wont be as crystal clear unfortunately.

Hi,

I tested it also in a quickly created Windows USB server and I see that when the cracking/stuttering occures the latency is instead of 1ms/2ms going to 10/30ms.... in the logging graphic.

Are the some aditional commands I can use or give prio to a device? Anything I can use to test is welcome.

In windows you can bring up task manager, find the vhusbdwin64.exe program in the details tab and right click and set priority high

In linux you can use the renice command
