Chromium + pepper flash + pulseaudio = static/crackling noise.

With pulseaudio and chromium+pepper flash from the AUR I get static/crackling noise in the audio. If I disable pulse and just use alsa I don't receive any static/crackling noise... Is there any way to fix it?

Did you already play with the "tched=0 option" and the other pointers mentioned in https://bbs.archlinux.org/viewtopic.php?id=164959 ?

[SOLVED] Both stable and unstable chromium-pepper-flash won't install

Hi all,
I just installed Chromium, but am unable to install Flash. It was recommended that I install pepper-flash rather than flashplugin, since the latter is deprecated. But there is a problem:
chromium-pepper-flash-stable won't install because the link to the package is invalid:
ERROR: Failure while downloading google-chrome-stable-31.0.1650.57-1.x86_64.rpm
chromium-pepper-flash won't install because the md5 checksum is invalid:
==> Validating source files with md5sums...
google-chrome-unstable_current_amd64.deb ... FAILED
LICENSE.txt ... Passed
==> ERROR: One or more files did not pass the validity check!
This leaves me with three questions:
Does this happen often, or is it a freak coincidence that both recommended Flash packages are broken on the first day I start using Arch?
I can probably find the proper package file for chromium-pepper-flash-stable, but what is recommended practice for installing it (if I am in a hurry, or just impatient)? Should I hack the PKGBUILD file myself?
Should I flag these packages as out-of-date in AUR?
Thanks!

Yes, edit the PKGBUILD yourself. Both the link and the checksum.
Have a look at the comments: https://aur.archlinux.org/packages/chro … mments=all Being broken is not an uncommon occurrence for this package.

Static crackling noise, Right speaker when audio is being played

I recently purchased this Satellite C50D-A Windows 8 Laptop. I have had it for less than 3 months. Recently the right speaker has started acting up with some sort of high pitched static crackling noise whenever audio is played regardless of it being in a web browser or any other media. Even computer sounds are distorted from this. I typically use this computer for school and play music to study. How the hell can I fix this so I can actually listen to audio without this rather irritating issue?

I tried that and it didnt seem to do much of anything.
I played part of a song on spotify and recorded it to perhaps give you an example of what it sounds like?
I covered the left speaker so most of what you hear is the right speaker alone. The distortion is pretty clear when audio comes out of that speaker.

Chromium pepper flash jagged image/controls/text when fullscreen

Hi. I'm testing the chromium pepper flash and it seems to be more responsive and more faster than regular flash player. I'm no longer affected by this https://bbs.archlinux.org/viewtopic.php?id=155503 issue too.
But there is an issue. When I go fullscreen, for example, in youtube, I get jagged text and picture. Just like this:
https://dl.dropbox.com/u/16222427/ARCH/ … 9%3A21.png
Maybe not the best example, because the artifacts are hard to see in this screenshot, but in motion it's pretty annoying especially in 720p+ videos. You can see that the font is jagged and the controls at the bottom look just like that. Anyone getting this too?
I've tried both packages that are in AUR. This occurs only when fullscreen.
I'm using XFCE, latest kernel from core repos, x86_64 and chromium from core repos. I tried chromium binary version from AUR and it didn't help.
Oh, and with regular flashplayer, it's fine, just a bit slower.
EDIT: this is a screen when watching 360p, looks even worse, looks like the picture is not stretched corectly.

[SOLVED] chromium-pepper-flash fails to install

I use chromium-pepper-flash and today there was an update, but the install script has errors.
Sorry for the locale, but summarized it said cat and sed didn't find a file.
Probably the chromium-pepper-flash.install cannot find the $_default as it says
[ -f etc/chromium-browser/default ] && _default='etc/chromium-browser/default'
[ -f etc/chromium-dev/default ] && _default='etc/chromium-dev/default'
[ -f etc/chromium/default ] && _default='etc/chromium/default'
Anyways the installation was successful.

*Important--iPhone4s Static/Crackling Noise

All,
There seems to be an increasing number of complaints coming in of iPhone 4s static/crackling noise coming from the phone when placing calls. I personally had the same problem on an iPhone received 10/14. Replacement devices seem to be having similar problems. Here are the following symptoms:
-Very intrusive and abnormal crackling/static noise can be heard through the ear piece while on a call. More obvious in a quiet room.
-When call ends, the sound can STILL be heard coming from the back of the phone. Which means the source of the noise may be coming from there?
-Atleast one person noted that the noise can be stopped by shorting out the signal by placing hand over two top antenna bands forcing a "switch".
-Replacement devices are having same symptoms.
Is anyone NOT having the the symptoms described on the new iPhone4S?

Me and my girlfriend both got 4S's at the same time. Hers is on a Canadian carrier called Bell, mine is with Telus. Her phone does not have any of the crackling noise. My phone, whenever I made a call, would create a horrendus crackling through the earpiece before connecting the call. Sometimes, the caller would not be able to hear me. I also experienced the same crackling as everyone during a call, and even had to hang up a few times because it got so bad. I called my provider for an unrelated issue, but was able to demonstrate the issue to the tech. She had never heard of this, but suggested it might be a SIM Card or Hardware issue. I was inclined to agree. So after I got off the phone I proceeded to remove and replace my SIM. At first I turned my phone off, took it out, booted up the phone, and replaced it. The noise was now even louder than before. !@#$! So, I took it out again with the phone on, blew in the SIM slot, and ensured that the SIM stayed completely in the tray when inserting it. Voila, no more static. I suggest everyone give this a try before blowing up Apple. It could be you're SIM's were hastily inserted and causing some kind of short out interference. Hope this helps someone else!
TLDR: Take out your SIM Card with the phone on, blow in the SIM slot, and ensure that the SIM stays completely in place and in the tray when inserting it. I suggest everyone give this a try before blowing up Apple. It could be you're SIM's were hastily inserted and causing some kind of short out interference. Hope this helps someone else!

Fixed line static/crackling noise

Hello All Just want to see what ppl's opinions are on where to go from here. I've been a having a problem with static/crackling noise on the fixed line for about 2 months now. When Tech No. 1 came out, he said he changed something at the pillar, which is located somewhere between my house and the exchange. After he left, I got a text message saying the line test was ok. But it wasn't really ok, but I left it to see if there were any improvements. Fast forward to two months later, I noticed the noise was just as bad. So I reported the fault online and got a call from a lady the next day saying the fault would be investigated and repaired within x number of days. Then on Sunday, Tech No. 2 came out to my house without any notice at all. He too said that he changed some part. The line was actually ok when he called my home number using his mobile. But today, the noise is back. Should I report the fault again and hopefully one day Telstra might actually replace the line? What do ppl here think? Thanks.

If it's within 14 days of the callout by the engineer, you should be able to get an engineer out on the same incident. Definitely call, and have it checked. I asume you have filters, and no doubt they've told you that "if the problem is on your equipment then you pay the cost" etc etc So it's obviously outside your premises, and there may be something seriously going wrong on the lines/exchange if it's simply not lasting.

Static/crackling noise in earbuds

I have a strange static/crackling noise in my earbuds (plugged into my iMac) when I have my iPod touch connected to the computer. It stops when I turn off the iPod completely or plug it out (not when I put the iPod touch to sleep). How can I get rid of the noise, it's pretty loud...

u cant get rid of the white noise, its common among all stereo devices, its just amplified on the touch. I say: just live with it.

[SOLVED] Chromium + pepper = Video @ double speed

I am using the latest stable chromium, with the pepper-stable package from the AUR recommended in the Chromium wiki.
I moved to Chromium as Flash is no longer being developed for Firefox....And Firefox 26 crashes a lot, and randomly, including with all plugins removed. So It's a problem right now.
As the subject mentions....I am getting weird video issues. Usually, the video plays back at double speed, with the associated spastic audio output. Here is an example: Ref: http://www.youtube.com/watch?v=smCQ2g9L7PU.
This used to play fine in Firefox with the old flashplugin.
In my porting process, here is what I did:
With no browser open:
a) "sudo pacman -Rs flashplugin"
a1) Verified that flash was no longer operating in Firefox.
b) "sudo pacman -S chromium"
c) "yaourt -S chromium-pepper-flash-stable"
d) In chromium: "chrome://plugins" to verify that flash wasn't showing up.
Arch x86_64 (current), NVidia GTX-660, using the nvidia drivers from Arch...extra. (rev 331.20) vdpau is installed in both the 64 and lib32 variants.
I have tried disabling hardware acceleration in the pepper-flash plugin, restarted the browser and retried. I have tried enabling hardware acceleration, restarted the browser and retried.
Playback seems unaffected in either scenario, and remains unusable.
Gnash has never performed properly for me in any scenario where I've tried it. So Gnash is not an option. Gnash has a long way to go until it is ready to be a good drop-in replacement for an official "flash plugin".
So for now, I have to use the smtube for smplayer to view YouTube/major news site videos properly.
I am requesting, please, some assistance in fixing my video playback issue in Chromium.
Sincerely and respectfully,
Dave
PS: I'm curious, why does the firefox community appear to be sitting on their hands when Adobe has made it clear for a long time that Adobe Flash for linux is being abandoned as of 01-JAN-2014? I would have expected some really heavy programming resources to be assigned to gnash to make it better, or write some sort of wrapper for the chromium pepper plugin....for official Adobe support.
Is there another reliable flash playback mechanism that I am missing all together?

Problems Viewing Pepper Flash Under chrome://plugins

Hello all,
After an update, my flash seems to be gone.
I downloaded the chromium-pepper-flash-stable and did 'makepkg', but I still get the warning message on some sites and
the enable flash plugin option does not show under chrome://plugins

There is no 'chromium-pepper-flash-stable' in the AUR anymore. It was renamed w/o the 'stable' part.
In any case, I think fungle may be on to something here... you may have built it, but did you actually install it?

Soundsticks (USB) crackling noise

Hi,
I experience constant static crackling noises from the Soundsticks when they are connected to the Computer (an iMac 20" from late 2006).
No matter if the volume is turned down or muted on the Soundsticks, no matter if I select the internal speakers as the output source, it does not go away.
Does anyone else have this problem?
Thank you, bye.

Hi DaddyP,
thanks for you reply. Have tried as you suggested but unfortunately the crackling does not go away. But what I found out by trying that is that it seems not MacOS related because even unplugging them from the computers' USB port does not stop them crackling.
cheers.

Trouble installing pepper flash plugin for Chromium

Hello. I've been trying to install the pepper flash plugin for Chromium via the Chromium Plugins package in the AUR here: https://aur.archlinux.org/packages/chro … per-flash/ . I successfully extracted the tarball, built the package and installed it using pacman. After restarting Chromium, however, the only new plugin I see is the Chrome PDF viewer; no pepper-flash plugin is visable. I thought about maybe installing the flash player that you can download from Adobe's website but I don't know if that would interfere with the plugin I should have already installed. Any advice on how to get this plugin to work in Chromium would be great. Thanks.

I have pepperflash installed on my chromium and it identifies itself as
Adobe Flash Player - Version: 13.0.0.214
Shockwave Flash 13.0 r0
Name: Shockwave Flash
Description: Shockwave Flash 13.0 r0
Version: 13.0.0.214
Location: /usr/lib/PepperFlash/libpepflashplayer.so
Type: PPAPI (out-of-process)
This is in about:plugins url and is not an up-to-date version, but it works. I'll try updating to the newest version and see if it breaks things

[solved] Pepper flash out of date?

Just reinstalled the system (64bit), downloaded the latest chrome and extracted pepper flash to chromium. It always worked flawlessly but this time it's saying that the plugin is outdated and can't be used. This is just an annoyance since we can set whatever version we want in /etc/chromium/default but I was just wondering why it is happening and if others have experienced such behavior.
Last edited by Matt3o (2013-01-24 10:12:22)

I've done exactly what the AUR package does, but manually.
- download latest 64bit chrome from google website
- extract pepper flash
- copy files to proper directory
- modify /etc/chromium/default
in fact AUR package gives me the same out of date error
Edit: my workaround is to add some units to the --ppapi-flash-version paramenter in the /etc/chromium/default

Pepper flash not loading in chrome

I have exhausted my google-fu on this issue, which I also had in other Linux distros. The issue is that pepper flash doesn't show up in the list of plugins in chrome://plugins at all, no errors when chrome is started from a terminal, and no indication that anyone else seems affected by the problem based on poring over the search results for a stupid amount of time.
My system is old. It's a Compaq based on an Asus A7VBX-LA motherboard. I have an Nvidia Riva TNT2 graphics card. System memory is 512MB.
I really hate flash in any form. I installed gnash a while back just so my daughter could watch youtube videos, but now she wants to be able to use sites like Hulu and no combination of gnash or adobe flash with any browser seems to work, so I thought I'd try chrome with pepper-flash. This same thing happened in Debian Jesse with this hardware. My best guess right now is that the software is laughing at my hardware, but I wish it would do it to my face an at least print a message to the terminal that my hardware isn't capable of using the plugin.

I don't think it's your hardware. I'm having the same problem with an Asus EEE 1005 (netbook). I have the updated version of Chromium (30.1) and the chromium-pepper-stable installed (and I confirmed that the so file is there). But Chromium doesn't see the plugin. It sees the Adobe Flash plugin, which I've disabled (but use with Firefox-Nightly, so I don't want to uninstall it).
The Wiki says simply disable one and enable the other. It offers the possibility of installing Iron (a Chrome clone) and running it from the command line in order to invoke Pepper Flash, but it seems not to imagine that the plugin won't be visible in Chromium.
I'd keep working on this if I had any ideas, but I don't. I'll just hope that updated versions of the plugin and Chromium work at some point.

Possible legal case issue with google chrome pepper flash player.

Ok so i have been on the phone to adobe for about an hour and this is the result.
As far as adobe are concerned their flash player works fine which it does.
However the google chrome Pepper flash player is obviously broken.
Now adobe say this has nothing to do with them their flash player is fine and googles version of adobe flash player has nothing to do with ADOBE either.
So why when you go into chrome plugin settings it says ADOBE flash player.
It doesn't say Google Flash player.
It says ADOBE Flash player.
So it seem to me that either google have stolen the Adobe flash player then made their own and broke it. OR Adobe let them make their own version and is fully aware of the issue but doesn't care?
How can Adobe ignore this issue for so long is disgraceful.
Adobe should be in contact with google saying what have you done to OUR Flash player.
Please the CEO of adobe should sort this out OR at least provide evidence that google hasn't stole Adobe flash player and broke it.
This situation is completely unacceptable and i belive a legal case should be opened if Adobe has NOT given permission for google to use and implement a version of ADOBE's Flash player.

your not going to like this, but i would of said the exact same thing myself, im a flash developer, i use chrome as my main browser with pepper running for general use. and from day to day im looking at javascript websites with simple little flash video players and adverts with spinning bitmaps, with no issues apart from the usual crashes when running flash videos, followed by that "oh snap" error message, which im sure the 18 year olds developing chrome find very ammusing. And of course when im developing flash applications im using the debugger version of the flash player in all my browsers like you should do, then i come to test my app on a pepper enabled instance of chrome one day and oh look at that nothing works. maybe if your running some basic timeline animation of a spinning dollar sign or a youtube video with some kids jumping off a roof it works, but a hell of alot is broken, loaders, loading fonts, uploading files, reloading cached files, and a plethora of things iv read in forums that i cant even get to try because i cant get anything to load consistently or find a debugger version of the pepper player to do a getStackTrace. i tried emptying all the caches and data from hosted apps, i tried deleting preference folders, tried recreating flash projects in flash builder from scratch, tried different versions of windows, tried testing it in the chrome beta, but that's even worse because instead of posting an error message it just hangs on a black screen in my app. none of this happens in any other version of the flash player i have tested so far, im tracking all errors that users of my app run into by logging them to a database and all of them are specific to pepper, and reproducable. In chromes bug reporting section there's a long list of these kinds of issues, its been like this for months, peoples businesses are being ruined by this stupid tiny little .dll file and the only solution anyone has found, other than the odd hack that fixes some bugs like setting video resolution to 479 instead of 480 to make a video stream play because google didnt bother to test anything other then the most basic default functions... Is to just throw a warning message to people with pepper player to go into their chrome plugins page, press a tiny little button in the corner to show some complicated dll file information, press another tiny disable button under the not very well marked pepflashplayer.dll, and then select always allow at the bottom so you don't have to deal with chrome blocking any working flash player other than pepper from running because its out of date. which in the end probably takes longer than installing the real flash player in the first place, there is literally no need for this damn dll file to even exist and for some mind blowing reason it has the exact same version number as every other flash player i have tried, which all work flawlessly. and also then obviously most people ignore the warning messages, continue to use your app wonder why its crashing, get frustrated and leave... So my only alternative so far is to totally block anyone using pepper player from even being able to load my app and tell them to do all of the above or use Internet explorer which seems to actually have a working built in flash player. so that instantly cuts out, as ofFebruary 2013, 50.0 % of Internet users unless they boot up internet explorer then manually navigate back to my webpage. which can make a huge dent to the amount of people who actually bother to even try your app.
Now you may be saying to yourself "well he sounds a bit miffed about this pepper player that for me seems to work fine". maybe there's some kind of hack way to get swfs running in pepper that only some of you in the know, know about, google doesn't have any answers, when i rang adobe they were utterly clueless, when i rang google there wasn't even a human being to talk to from that faceless corporate monstrosity. and iv got 4 years worth of development time riding on this damn flash app which, unless adobe pull the plug on pepper, or google learn how to bundle other peoples software. is totally useless just as im trying to deploy it, and im going to have to copy and paste the whole lot into some .js files and try to reverse engineer it all into javascript which means gutting all the stuff that you can only do in flash, which is about half of it. now obviously you start asking questions like, how could it be possible that a version of flash this flea-ridden was ever allowed to be let out into the jungle when sooooo much is at risk for certain types of businesses that rely on this technology. you could literally put people out of a job by doing this, the man on the phone from adobe says well its not our problem its googles version and they are in charge of it, well if that's the case you better pull the licensing quick fast because it makes adobe look bad and the the flash brand look even worse. normal chrome users who arn't even trying to peddle their wares made in flash are even complaining that its "poisoning" their beloved chromium, and the most they have to suffer with is a buggy experience in a flash game but those of us with serious time and work invested into flash and businesses based on it are utterly fuming.
Now, either you think this is all nonsense, you see no evidence, i must be doing something wrong, and all these cases im reading are just my imagination. Or you are fully aware of this situation and you are just saying the thing devs including myself always have to say to our users when we don't have a good answer or time to worry about it "Everything works great on my system, just submit a bug report". or you are so disconnected that you simply don't know about it yet and this is just a total waste of my time and anybody worth talking to his hidden deep in the bowels of adobe barred from communicating with the outside world.
What i want to hear is that indeed you are fully aware of and informed about these issues, and within 1 month the pepper player will be removed from chrome and users will be allowed to use the official flash player from adobe which will remain stable and fully functional.

Chromium + pepper flash + pulseaudio = static/crackling noise.
