Post subject: fixed-Annoying noise in audio flash videos in some websites
I did an update on Aptosid KDE 64bit, I am using adobe 64bit flash plugin, on "some" websites such as imdb movie trailers, flash videos are played with an audio which comes with lots of annoying noise. The video itself is played smoothly without any problem but the sound is terrible. To my astonishment, this problem shows up only on a number of web sites, and on others such as youtube the sound is clear. Any idea?

I do have the same issue. My machine does have a fresh installation (2011-01 amd64). On 'http://www.wdrmaus.de/kaeptnblaubaerseite/baerchen/tv2.php5' I've got this amazing noise. On youtube the sound sounds normal. I use the flashplugin-nonfree also.

I can confirm this is happening on x64 with flash from repos. I noticed this first happening about 1 week ago and have been trying to figure it out on my own. Like you say some flash is affected and some not. I'm thinking the flash sounds may have been written for an earlier version and the latest version isn't backward compatable. I'll follow up after more testing.

      Code:

More info: You have version 10,3,162,29 installed

apt-cache policy flashplugin-nonfree
flashplugin-nonfree:
  Installed: 1:2.8.3

System:    Host siduxbox64a Kernel 2.6.38-5.slh.1-aptosid-amd64 x86_64 (64 bit) Distro sidux 2009-03 Μώμος - kde-lite - (200911110039)


Adobe site recommends 10.3.181.14

Same here. Any solution around?
Strange as flash plugin is months old and the noise is since days.

I recognized this a couple of days ago on this site: http://www.simfy.de/. Therefore I'm also very interested in a solution to this. (Also using AMD64)

works and sounds great on 32 bit ('http://www.wdrmaus.de/kaeptnblaubaerseite/baerchen/tv2.php5')

cannot test http://www.simfy.de/ due to international rights agreements, service is not located in my country

@piper, on 64-bit I can hear the problem on http://www.wdrmaus.de/kaeptnblaubaersei ... n/tv2.php5

here in USA. Also you can hear it on imdb trailers, for example http://www.imdb.com/title/tt1179034/

Sounds like a decoding frequency mis-match, producing a "thumping" or "pumping" of the audio channel.

Would installing the latest 32bit flash using nspluginwrapper fix it? The 64 bit preview for amd64 is rather old.

Does that patch work for the 64 bit version too?

I only have 64bit, so yes.
gerd - 17.05.2011, 20:55
Post subject:
The bug is only appearing in the 64 bit version so the patch is for 64 bit.

Thank you gerd!

Everyone (like me) does not understand the details of patching with bsdiff -- you have provided excellent help. Very Happy

I noticed the artifacts in certain videos too, i thought it had to do with the BBC site.

      Code:
# apt-cache policy bsdiff
bsdiff:
  Installed: 4.3-10
  Candidate: 4.3-10

      Code:
/usr/lib/flashplugin-nonfree# bspatch libflashplayer.so libflashplayer.so2 memcpy-10.3.162.29.bsdiff
bspatch: fopen(memcpy-10.3.162.29.bsdiff): No such file or directory
What's wrong or what am i doing wrong?

did you fetch http://bugs.debian.org/cgi-bin/bugrepor ... bug=620901 and place it in /usr/lib/flashplugin-nonfree? before issuing those commands?

I'd been living with this bug for months, as it only affected certain web sites, before I finally tried to fix it and found this thread. I don't tend to upgrade Adobe Flashplayer much and so didn't realize that this issue had been fixed in an update, as is stated on the Debian bug page. I decided to try a Flash update before I checked out the bug page.
      Code:
update-flashplugin-nonfree --install

The version of Flash you have is rather old now...Flash 11 is out and is a native 64 bit plugin as well.

Yes, I didn't even check the version before I upgraded, but looking at /var/cache/flashplugin-nonfree, it looks like it was version 10.2 from Nov. 17, 2010. Shocked Now, I can watch all the stupid pet videos on Yahoo with good sound ... Smile It was also annoying for news video on some sites.

Now that I found out this is a Flash bug, maybe it's time to just uninstall the thing: http://occupyflash.org/ Arrow HTML5

In due time you won't really need the Flash plugin once HTML5 really takes off...goodbye Flash crashes and bugs!

Future apps in the workplace should also move away from Flash based apps to HTML5 as well as supporting the latest browsers.

@alexk thanks for the reminder... I completely forgot I had to manually update flash. I should add that update to a weekly cron job. As much as I don't like the flash code on my computer, having it was one of the major reasons I was able to get my wife to try linux, and my 2yr old likes to play flash games on it too.... I want to get a video of "I'm two and I like linux".

Adobe is now targeting Flash for desktops/notebooks so here's hoping they'll get off their duffs and make it work for those apps that need it.

Nice..a 2 year old that likes Linux Smile

A future Linux kernel developer he/she could be :^)
