No audio playback in several apps

I can't get audio playback in several streaming apps. So far it's RealPlayer, YouTube, and Google Video. They will play the video, but there is no audio, regardless of volume, muting, etc. I do have audio in QuickTime and stuff streaming through Flip4Mac.
I first noticed this yesterday, and it started for no apparent reason. I restarted, nothing. I tried restoring and reinstalling RealPlayer, and it didn't fix it either.
Any ideas on how to fix this?

I am having a similar problem - I get audio from iTunes, but not from QuickTime or RealPlayer? YouTube plays audio just fine.
My OS is at 10.4.8 to stay within the Pro Tools supported realm.
This is both for streaming and any local media - I've checked my sound prefs and all looks fine - output is to internal speakers or headphones (if plugged in).
What could this be?

ATV (Gen3) Newest updates severely distort audio playback from iTunes. Please Help!!!

I just updated my iTunes and ATV (Gen3) to the newest versions and immediately noticed severe distortion in audio playback from iTunes library. No hardware changes have been made and yesterday the sound quality was just fine. I have one running an optical cable into a high end receiver and another running off a HDMI cable into the TV with powered Speakers for output. I checked both systems on all inputs and it's only the Apple TV with the distortion. Someone please help as that is the only thing I really use on the device. iTunes version 12.0.1.26

Weird, I just opened iTunes to add some songs and now its playing fine.
Though I still can't figure out how to change the columns and having them stick to what I want .

Audio switches from Podcasts app to Music/iPod app

It is not happening consistently, but several times the audio playback on my iPhone 4 (iOS 5.1.1) has switched from the new Podcasts app to the Music/iPod app with a simple stop and start using the button on my headphone. Anyone else experiencing this?

I've had this issue with all sorts of apps. Sometimes when pausing playback in Safari/iTunes etc. and then restarting it will start the Music app. Don't think it's an issue with this app in particular, but rather with the background audio API. Part of me suspects that the app is being killed to free up RAM, so the OS defaults to the music app.

AIR + Android audio playback in background

Hello everbody,
at the moment I am evaluating the realisation auf a radioplayer using a rtmp stream for android devices.
There are two question for which I could not find any advices or resoltions.
My questions are:
1.) Is it possible to play/continue an audiostream, even if the app itself is pushed into background?
2.) How are updates handled for apps in Android-Store? Is it the same as with the updateroutine for AIR on Desktops?
Thanks in advance for your answers.
Regards,
wman

Hi Varun,
thanks for your answers.
Are there any ressources/links, maybe on adobe devnet, available for audio playback while app is in background?
I already searched the web so far, but could not find any hints.
but anyway thanks for your response!

Touchpad - Bluetooth audio streaming works Preware Apps, not App store Apps

Hi,
I'm having an issue with any applications I've installed through the App store not streaming over bluetooth.
Any app installed with Preware streams audio just fine.
I haven't tried resetting the touchpad to factory condition..
It's mainly an issue since Grooveshark seems to have been added to the App store and I (stupidly) updated my preware app to the app store one.
No, this is not the only app that doesn't stream over bluetooth.
I am streaming to my Pioneer VSX 821 K.
Anyone have any experience with this issue?
Anyone resolve this issue before?
I tried searching the forums for bluetooth type posts but didn't see anything related.
Thanks
Post relates to: HP TouchPad (WiFi)

FYI, if you've opened the Shazam app, it messes up the bluetooth playback with Pandora (maybe other apps too) you have to close the app completely in order to restore normal audio.
So you might want to close all apps competing for the audio playback, and only do one at a time. Apple and audio players have messed up playback on the iPhone.
Does Google Maps audio work over the bluetooth connection?
Is this a built-in bluetooth or is it an add-on system?

Premiere Pro CC & OS X Mavericks Audio Buzzing & Audio Playback Issues

Working on the latest version of Premiere CC version 7.2.1 and MAC OS X 10.9.1. I am experiencing a really loud disturbing buzzing/cutout sound in playback. I have tried changing every audio setting possible on my mac and in the Premiere CC Audio/Playback settings. Sometimes changing the audio hardware or playback preferences fix it, but only for a few minutes. This is beyond a deal breaker for me. We need a fix for this, been dealing with audio issues with Premiere since CS6, nonsense.

Please someone help me with this, im deep in a music video edit and dont know what to do, im working at a snails pace on a really fast machine.

If the problem is limited to audio transitions, then you're probably hitting a bug that was introduced in 7.2: http://forums.adobe.com/message/5945929#5945929. A fix went into 7.2.1. For projects that you worked on in 7.2, I believe you need to clear the cache and, possibly, the preview render files.
Several users have reported that the fix in 7.2.1 did not resolve the issue in all cases.

I don't know what the status is on any bugs that remain in this vein. If all else fails, your best bet may be to revert to 7.1. Unfortunately, that's not as simple as it could be. See the instructions here: http://forums.adobe.com/message/5823746#5823746

Bugged audio playback? When I start working with more than 1 audio track.

Hi!
I have been using premiere elements 12 for editing FullHD videos.
Brand new for me just bought it like 2 weeks ago.
Now during the last couple weeks I have had this MAJOR proglem with editing the audio.
This problem is headache and turns my simple editing into almost impossibilites.
I have had this problem with all my projects. _ALL_
Usually the problem seems to appear when I want to start working with several audio tracks.
At somepoint my projects just get ruined, I simply cannot hear the audio tracks.
The audio starts to disapear randomly from all the audio tracks.
It is not only playback problem. When I exported the video, the audio was partly missing, same as the project.
I have tried to look help on forums and search all what I could find, but havent been able to solve this.
Small fix has slightly helped:
I export audio to single track and bring it back to project. This works but I still usually have more editing to do.
I simply cannot understand why the playback disapears, I fear it is a bug.
I found lot of earlier version problems on people with similar type of problems, but no help for this version of program.
To solve the matter I have changed my audio setting in PE12.
Tried Premiere Elements WDM Sound and ASIO4ALL V2, but same problem on both.
I have looked up that my audio playback device and PE12 matches, and are not muted, and volumes maxed.
I have deleted my C:\ appdata\roaming\adobe premiere elements & premiere elements 12 folder preferences.. not helping..
I press the update pretty much everyday hoping for new version.. But yes, program keeps telling me its the latest.
I usually only work with 3 audio track maxinum. And I am doing really the most basic stuff here..
I have set all my audios to foreground and it has given me best results, but it does not seem to take the problem away as at somepoint randomly my audio playback is missing again, randomly across the playback.
Please anyone? I am feeling hopeless here.

First of all, thank you for replying my message!
I will go and try to answer best I can.

In total sizes of audio involved is usually something like 300mb
What are you or the program setting as the project preset in the new project dialog. See Edit Menu/Project Settings/General and its Editing Mode, Timebase, and Frame Size readings.
I opened new project and this is what i got:
Editing mode: HD 1080i
Timebase: 25,00 frames/second
Frame size: 1920 x1080
Audio is 48000 Hz
(I dont know how to change these, btw. Program don't seem to let me change editing mode.
I also looked up my most recent project and found these settings:
Editing Mode: DSLR
Timebase: 30,00 frames/second
Frame size: 1920 x1080
..and same audio settings
Do the problems persist if you start a new project? Do you find the audio problems develop when the Timeline content is fairly well developed or can the problems occur when there a minimal amount of content of those tracks? Let us look at the size and duration of this project.
Yes, I have had this problem with all my projects. Sometimes it goes away tho, just enough for me to work bit more. My work progress usually starts by clipping the video material, like 1h material to 8minutes in clips. After that I want to work with audio tracks, and here problems start! When I start working with more than 1 track, so the problem is at later stage. To fix the problem a small fix I have used, I export audio like music and effects tracks together to 1 wav and bring it back. After that, I start working with narrate track. To describe the problem with audio:
Audio Randomly starts to disapear when I playback, and can also be gone if I export the video out.
My source videos total size are usually within 80Gb max limit and audio edit material 300mb total.
In my last project my biggest source video was 47GB and leingth of 1h 4m, in addition to that I had 3 smaller videos, sizes of 1GB, 1,54GB and 300MB.
Is there any evidence that you are accidentially moving the audio track rubberband to alter the audio volume. That rubberband is the orange line that runs horizontally through the middle of the audio clip when you are looking at the wave form display style of that audio track. The rubberband represents audio volume.
No, audio volumes might have been adjusted in my tracks but they are present. The problem is usually like ~2-5seconds, a random audio track can be heard (like music or narrate) or just no sounds at all. This makes it very difficult to work with the audio. Also I gotta say that this problem starts by simply having the 2-3 audio tracks.. In my recent project the only adjustment I used to edit the audio was fade in/out.
I don't have any other audio problems with any other programs.
I am more than happy to provide more information if needed. I hope this information helps.
In addition I can say that when I close Adobe Premiere Elements 12, it crashes. No idea why.
I have also looked up my firewall settings, anything involved adobe and premiere..
In addition some effects like HD text templates make "Adobe Media Core CS6" crash. I tend to just not use em, or if I need em, I add em at end of the edits.
I hope this helps, I would really like to solve this problem.
Thank you alot for taking the time to answer! I welcome anyone to help mee too! Please giev links to similar problems too. Thank you everybody!

Randomly Pausing Audio Playback/Restoring Question

My iPhone 3G will on it's own, randomly pause audio playback (Pandora, iPod) when a 3.5 mm jack is plugged in, this takes any-wear from 10 secs to 30 mins, and this never happens when I use Apple OEM iPhone headphones. I went to an Apple store and the proposed resolution was to restore my iPhone as new. So my first question is: if I restore my iPhone as new, load music and a few apps on it and this does not fix the problem, can I restore my iPhone to the current state that has all my apps and data? My other question is, does anyone else have this problem?
Thanks!
-Mike

I don't have this problem.
But your question about restoring your phone to it's current state, yes. When you plug your iPhone into iTunes, right click on the phone in the column on the left and select "backup phone". (That is if iTunes doesn't automatically start syncing/backing up.) After that you perform a restore which erases the phones and updates to the current version. At that point, iTunes should prompt you to install the backup.

Crackling and skipping in audio playback

I am experiencing an occasional skipping in audio playback in my new Classic. It is not limited to just the music player app, it also occurs in the youtube app. It seems to happen most at the beginning of a song. Has anyone else experienced this issue?

I also noticed this problem recently. Device is 1 week old and I can hear it both when on external speakers and on headphones. But it's most obvious when on browser based youtube. The mp3s I tested with the built-in music app are high quality.

I've already tried quite a few things, trashing preferences, disabling out external hd, repairing the disk, repairing the user settings.
Has anyone an idea that could help me solving the problem?

Hi-
The "Exception: EXCBADACCESS (0x0001) Codes: KERNINVALIDADDRESS (0x0001) at 0x6c000004" report is often seen with memory related issues. Have you verified your memory with AHT or Rember?
The "Exception: EXC_BREAKPOINT (0x0006)" could be a different issue, implicating (in Thread 4) the "com.apple.soundtrackpro" plist, and/or (after prior thread 3) loading of the
"com.apple.audio.midi.CoreMIDI".
Amoung the preferences that you trashed, was "com.apple.soundtrackpro" or "com.apple.audio.midi.CoreMIDI" among them?
The two could be related by way of a memory problem, or be seperate issues. The data transfer function returns KERN_SUCCESS if the memory was successfully written, KERNINVALIDADDRESS if an invalid or non-allocated address was specified or there was insufficient memory allocated at one of the addresses and KERNPROTECTIONFAILURE if the destination region was not writable or the source region was not readable. KERNINVALIDADDRESS report is implicating a problem at memory address 0x6c000004.
I would do some testing/verification of your RAM.

Several apps stopped working -- won't run

Macbook 2GHz 2GB
OSX 10.4.10
Hi all,
Today I've had several apps stop working -- meaning, when I run them, their icon will bounce a couple times and then disappear, and the program never runs.
Googling led me to try deleting pref files -- one program had a pref file, I deleted it but no difference. The other apps didn't have any pref files.
I've repaired disk permissions. I've uninstalled/reinstalled each program.
I've been using them with no problems until today. The Macbook did try a software update today, but kernel panicked in the middle of installing -- not sure if that could cause it. I've tried Software Update again but it finds nothing.
Any help will be VERY much appreciated. I've never had this happen before, and can't seem to find much about it.
Thank you!

Tutorial: What to do when a Mac OS X application will not launch
It’s a frustrating scenario: You click on a regularly used application only to find that it will not launch – either bouncing indefinitely in the Mac OS X Dock or simply providing no feedback whatsoever. There are a number of potential solutions for this problem, ranging from simple and relatively quick to more tedious.
Update prebinding Many cases of application launch-failure can be resolved easily by simply updating prebinding, via the following steps:
1. Log in as an administrator
2. Open the Terminal (located in Applications/Utilities)
3. Type: sudo update_prebinding -root / -force and press Return.
4. When prompted for a password, enter your admin password, and press Return again. The process may take a few minutes, and you may see various messages flash by. The process is complete when the Terminal returns to a normal prompt.
5. Type exit and press Return.
6. Check for the capability to launch the problematic application.
Kill process in activity monitor Killing an application-related process via Activity Monitor (click the item then press the 'Quit Process' button) can allow proper application launch. This is especially applicable in situations where a restart cures problems with application launching, as the offending process(es) will, of course, be killed by the restart process.
Launch Activity Monitor (located in Applications/Utilities), then find the process associated with the problematic application, then quit it and attempt re-launching the applications.
Delete appropriate .plist files A non-launching application can be the result of a corrupt or otherwise defunct associated .plist file (for more information on exactly what a .plist file is, see this series of articles)
Most of the preferences files that we will be talking about are stored in a folder named Preferences, and located in the Library folder of your home directory, e.g.:
* ~/Library/Preferences/com.apple.Safari.plist.
Go to the ~/Library/Preferences folder, and search for any .plist files that may be associated with the application you are having trouble with. Drag the .plist file(s) [many applications have more than one associated .plist file, so be careful to scour for all of them] to the Desktop, then re-attempt launching the application.
You can also use an application like Preferential Treatment to check for corrupt .plist files.
Re-install the application Try re-installing your application from its original media or download source.
If an Apple application or component is not launching properly, you might need to restore it from the Apple installation discs per the instructions in our tutorial "Re-installing Apple applications from a Mac OS X disc/update package using Pacifist."
Clearing caches Try using a utility like Tiger Cache Cleaner, OnyX, or Cocktail to perform series of system cache deletion routines. Go from light, to medium to deep (the ordinal levels are defined differently in each application), checking to see if your afflicted application launches properly after each.
Also, check the following folder for application-specific cache files that can be deleted, or at least temporarily removed:
/Library/Application Support (look inside the folders here for files that end with .cache, and delete them)
Make sure permissions are correct A range of permissions issues can effect Mac OS X applications, causing them not to launch.
In these cases, the first thing to try is a disk permissions repair routine using Apple's Disk Utility (located in Applications/Utilities).
Failing that, startup from your Mac OS X installation disc (insert it, then restart while holding down the "C" key). After the startup process is complete, go to the "Utilities" menu and select Disk Utility. Click on the First Aid tab, then click on the Repair Disk button.
In some odd cases (usually after a backup or when transferring backed up data back to a startup device), permissions on the "MacOS" directory (the directory that normally stores the executable binary in a Mac OS X application) can become incorrect.
In order to fix this problem, use the following steps:
1. Click on the afflicted application to select it in the Finder
2. Either click the application while holding the control key, or use the "Action" menu (the icon looks like a gear) to access the option "Show Package Contents"
3. Open the "Contents" folder therein, and then find the "MacOS" folder
4. Modify the permissions on this folder to give it "execute" permissions for all users. Do this by opening the Terminal (located in Applications/Utilities) and typing the following command (don't press return afterward):
5. sudo chmod 755
6. After typing this, drag the "MacOS" folder to the Terminal window -- its path should appear. Press return, and you will be prompted for your administrator password, which you should enter.
The "MacOS" directory should now have read, write and execute priveleges for the owner, and read and execute privileges for the group and others.
Check CoreAudio As noted in Knowledge Base article #301658, some Apple applications might not open fully or at all if the Digidesign Core Audio driver has been installed as part of a Pro Tools version 6.9 installation.
Apple says to follow these steps if you are affected by this issue:
* Updating your Digidesign Core Audio driver may resolve the issue. You can find the latest versions for Mac OS X 10.3 (Panther) and Mac OS X 10.4 (Tiger) at http://digidesign.com/download/coreaudio. If that doesn't help, continue to step 2.
* Open Audio MIDI Setup (/Applications/Utilities).
* Click the Audio Devices tab.
* From the Default Output pop-up menu, choose Built-in Audio.
Check for errant plug-ins Some application launch failures can be caused by problematic plug-ins or other add-ons. Safari and other Web browsers are notorious for suffering from this issue, as are some other extensible applications like iMovie.
Check the following locations for any recently added files, or any files implicated in error messages generated when you attempt to launch the problematic application:
* /Library/Internet Plug-ins
* ~/Library/InputManagers
Re-apply the Mac OS X combo updater Try re-applying the latest Mac OS X combo updater from Apple's software downloads page. Doing so can resolve issues with system components or delete specific files that can resolve application launching issues.
Create a new user account Try creating a new user account, and check if the application launches under it. If so, a user-specific corruption issue is likely at play -- see the above sections regarding .plist files and caches. See our tutorial "Common workaround -- create a new user account" for more information.
Archive and Install As a last resort, try performing an Archive and Install process, which will retain some user settings but otherwise leave you with a fresh Mac OS X installation.
Also, check with the application's developer for compatibility notes regarding the version of Mac OS X you are running, and revert to an earlier iteration if necessary.

I can't get any audio playback from FCP X (or Premier Pro for that matter)â¦

When I playback a clip with audio it shows good level in the meters but I get no sound from any device (internal speakers, USB headphones, 3.5mm Headphones etc etc). If I render out a clip the audio is there and plays back in QuickTIme.app.
There are a few suspicious things like not being able to adjust the Master level slider in Sound Prefs, it's locked to Max position. I first became aware of this problem when I left After Effect and went to Premiere Pro to do an video comp that AE was choking on. PPro handled it well but no sound. Decided to try doing it in FCP X even though the interface is hard for me to 'get' striaght away I found stuff online about travel mattes but still no sound. Very frustrating I have a deadline — don't we all ;-)
Any ideas?
I uninstalled SoundFlower just in case. No difference. In the Audio MIDI Setup Utility.app, PremierPro and After Effexts come up as discrete devices:
About to try zap the PRAM can't think what else to do although I found an article that says trash the audio prefs one by one.

Make an appointment to your nearest Apple Genius bar.

Audio playback stuttering using AirPlay under iOS 8

I encountered a lot stuttering in audio playback with apples music app and Spotify using AirPlay mode with my AirPort express. It occurs not only in background use, but also when the apps are on top. Reseted all devices, nothing helped the issue. Very annoying, it never happend in the previous builds. I think it's a iOS 8 problem and hope Apple solves it soon. My internet works fine at 50 mbit though.

I've contacted Apple Care lately, and though they where very nice and kind, they pretended to never have heard about the issue and claimed, it should work. they gave it to their developing engineers though. Let's wait and see...

Installed 10.5 which ruined audio playback,

nstalled 10.5 which ruined audio playback, so reverted back to 10.4, this cured that fault but is still not so good, so which was the best version to use with xp, bearing in mind i have podcast , movies and itunes u on there.

Yes, the main HD is still visible. Your answer actually sounds spot on. I havent had time to get on my system for several days with other things going on with work right now, but hope to work on it this week/weekend.
I will try to startup from the main HD and see where it goes. Thank you for the response.
I will reply back here when I get some info....

Audio playback frequencies are distorted...

All of a sudden, audio playback through my speakers/headphone jack is muddy and distorted. Sometimes, the vocal track disappears completely. This is not just in iTunes (where I've unsuccessfully tried to adjust the equalizer), it's also on Youtube videos. Sonos, which does NOT go thru system audio, sounds fine. I'm including etrecheck diagnostics. Thanks for any ideas. Oh, and the only thing that's changed, systemwise, is the latest Yosemite upgrade. The problem started after that, but not immediately after.

Will try. There are no cables/exterior connections involved here.
Oddly enough, this worked. I was unable to hear anything in Safe Mode, so just exited and rebooted (yes, I'd already tried rebooting, with no effect). Gave iTunes a shot, and am now back to normal.
Whatever works!
Thank you.
