Description Frans Leerink 2009-12-05 00:39:35 UTC

Version:           1.12.2 (using 4.3.1 (KDE 4.3.1) "release 6", openSUSE 11.2)
Compiler:          gcc
OS:                Linux (i686) release 2.6.31.5-0.1-desktop

Hello,

I receive via KMail My "YOUR LINUX TODAY NEWSLETTER's". 
If I open a newsletter in HTML format and scroll through the summary of the articles, the music my desktop computer is playing is distorted (very short disruptions/breakages, many in a second. It sound just like Louis Armstrong was singing. Every mousewheel click causes 3-5 disruptions/breakages) 

I will attach a screen copy of the newsletter and a copy of the newsletter mailbox file

Regards,   Frans

Linux Today Newsletter file

This is just an example file, the problem exists with all files

How can we reproduce this? Does this happen only with "Linux ToDay Newsletter" or with every HTML-mail? Does this happen always to you? Does amarok stutter in different situations?

Hello Bjoern,

Open the attached file id 38835 with kmail as proposed. Open the text document in html by clicking on body part html and then again on 2 popup windows.

If you than scroll through the articles while the computer plays in Amarok a quiet song you should hear the twitter. You hear it also if you scroll through the text version of the document.
It is not restricted to the Linux TODAY Newsletter, it happens allways by reading mail via Kontact/kmail, as long I use the scrollwheel. Clicking with the mouse on the scollbar does not cause the stutter effect.
Amarok does not stutter in other situations, like scrolling with the mouse wheel through a large pdf document with ADOBE Reader.

Hopefully this helps

Regards, Frans

This must be someway caused by your sound server not running with enough priority. I think here is nothing kmail devs can fix.

How can I find What priority my sound server used and what should it be and where/how can I set that

That is beyond the scope of the kde bugzilla. Can you search for stuff like "pulseaudio stutter" or similar in the web? Here you will probably not get much help about your sound server.
