System Audio Starts Distorting

For some reason, I was watching a movie in VLC and after the crazy amount of skipping and dropped video and audio stopped happening, the audio was distorted. Not just the audio through VLC, but all the system audio. Even iTunes, or just the blips changing the volume were distorted. I think it's a memory problem cause I was using a lot of different programs at the same time, but when I open up Activity Monitor and get rid of some stuff, it still won't go away.
It has gone away now, but what if it happens again, is there anything I can do to get audio up and un-distorted immediately when it happens?

that really did nothing
in the audio tab, it displayed that audio output was unavailable
i don't think it has to do with anything like that, just memory, because whenever I'm downloading a lot, or have things working, exporting or anything, it goes from skipping playback, to distorted audio. I was just wondering if anyone else had experienced this cause it really ****** me off every time it happens.

XBMC: HDMI audio starts out OK, then gets distorted after few minutes

Hi,
I have posted about this on the XBMC forums, but one of the developers kindly informed me that they do not support XBMC on Arch Linux in any way, so I should take my queries elsewhere. I am hoping that someone here might be able to shed some light on my issue.
I am trying to use XBMC 13.1 (xbmc-13.1-2) with Samsung EH5300 32" Smart TV (2013 model) over HDMI connection. The HTPC computer is AMD-based (AMD A4-5300 APU, which includes Radeon HD 7480D GPU), and runs an up-to-date Arch Linux (last full system upgrade on 2014-06-26). I am using the open source "radeon" driver (xf86-video-ati-1:7.3.0-1). Everything has been great except the sound:
The sound starts out fine, but a few minutes later it begins to get distorted. At first it sounds like reverb affecting voice only, but with time the distortion increases until it sounds kind of cued TV noise. If I restart the video, the sound works again for a while. If I change options in Settings -> System -> Audio Output, like the number of channels or pass-through, the sound is again good for a little while. If I enable or disable "Stereo Upmix" or change audio stream from the "Audio - Settings" dialogue window available during video playback, it too seems to "reset" the sound to sounding normal for a while.
Has anyone seen something like this?
I have tried different videos, and it seems like HD videos are affected more than SD videos, starting with distortions only a few minutes in (except the one Xvid video, which was fine for 15 minutes). Some SD videos are completely fine, some start having distortion issues only after 20 minutes or so. Judging from video information, if the video uses 5.1 channels (all HD videos fall in this category), it definitely gets distorted; if a video only uses 2.0 channels (like the SD videos), some are fine while others get distortion later on. I have "Number of channels" in Audio Output settings set to 2.0. Changing this (or any other audio settings) has not affected the distortion.
Following Arch Wiki: Radeon note about HDMI audio, I tried adding radeon.audio=1 to the kernel line; this did not solve the issue, just added some visual glitches.
In the XBMC debug log I posted, the distortions happen at around 17:26, though there is absolutely nothing logged at that time, even though I enabled "Verbose logging of AUDIO component" in the Debugging settings. The video I was playing there showed the following in the information window: 720 H.264 dts 5.1 16:9.
Any suggestions, ideas, or experiences would be appreciated. It definitely seems to be XBMC issue, since I was able to play the same HD video through mplayer without any problems (for at least half an hour, which would have already showed distortions several times through XBMC).

Hi GDykes,
OK Imagine that Connection speed from your ISP is like an empty freeway. You can go full tilt (upto that road's speed limit)
Bandwidth is like a busy freeway where you only get to go as the bit you are in allows.
Reducing the Bandwidth in iChat or in the System Preferences > Quicktime > Streaming tab is like a vehicle that has a maximum speed that is slower than the speed possible on the freeway.

Captivate 7 is not capturing system audio, and the software has a broken link

The Problem:
Captivate 7 is not capturing system audio. When I start a screen recording, the line with "System Audio" and its checkbox are eternally grayed out. Next to the grayed out words is a link that says, "Why is this disabled?"
The lnik goes to: http://www.adobe.com/go/cpaudio
Which is not a valid link, so Adobe's site redirects me to blogs.adoble.com/captivate which is ZERO help. Both browsing and the search bar bring no answers.
The Device:
Apple Macbook Air, Mid 2013, running OSX 10.9.2.
What I've done already:
Obvsiously I have set Captivate 7's preferences to capture system audio, and have set System Settings -> Security and Privacy -> Privacy -> Accessibility to allow Captivate to control my computer.
I have also tried clicking the Mic icon, Selecting Source with the System Audio icon and that doesn't record system audio either. It acts like it is recording system audio, but when I stop recording I get a popup that says, "Cannot record system audio. Ensure that you are playing audio on your computer [Okay]"

It's a wierd one.
One thing to try, and this fixes a lot of things, trash your preferences.

Second System Audio

Okay, so I edited my movie using the camera audio. But we actually shot second system audio along with the camera audio (ran the mic to both the camera and a hard drive audio recorder). The video is locked. No more video editing. Unfortunately, I didn't have the second system audio in my hands before video editing needed to get started.
So, does anyone know of some simplified, not horribly time-consuming, method for replacing the camera audio with the second system audio? And, of course, keeping it in sync.

FYI, it wasn't as difficult as I thought it would be or people made it sound. Whole process took me 3 hours and a chunk of that was spent trying to figure out which track was from the second system audio vs the camera audio. Once the clips were merged, there wasn't really a way to tell just by looking at them. Another chunk was spent putting in some room tone and tweaking things.
I just merged the audio to the video. Put it in a garbage sequence. Set my in and out points to match the original edit. Copied over the new audio track to where the old had been. Boom. Done. FCP even knew if I messed it up and the new audio was out of sync with the video and displayed the + or - # of frames.
As for bad planning, it wasn't. The camera doesn't do time code. Period. There was no option to have any and it wasn't needed. The only thing I suppose we could have planned better was not having our audio guy suddenly having to go to the mideast for 3 months. Then we would've merged the audio and video up front. Probably would've been zero time savings when you consider that you'd merge takes you wouldn't ultimately use.
Just thought I'd put it out there for anyone else who may need to know.

System audio gets scrambled please help.

Hi,
I was rendering one sequence and exported using quicktime (no quicktime conversion settings), as I needed to add the chapter marker on it.
I exported it as reference file (Full file gave me problem with the fade out at the end of the video).
When playing it back on quicktime, I heard the audio produced delay and then started to get scrambled, like the end of Mr. Self Destruct from Nine Inch Nails. check on youtube to hear what i mean.
but my sequence exported from final cut was only composed by a stereo soft music and spoken stereo track.
I did lots of cuts on this footage works fairly well on the video side (ACVHD 1080p) but both spoken audio (still in mov) and aiff file need rendering. I did only one fade in fade out effects, music audio has -8 decibel.
Those are all the changes i did.
Scratches files are on usb external hard drive. big one. User Settings is AVCHD 30fps (29,97).
Audio is 48khz 24bit.
But among all the sequences (15) I exported just this one gave me problem. It is even one of the shortest ones.
Another problem is that when I play the sequence on Final Cut the audio stops at the same point all the time
(1 minute and 10), and also this time the whole system audio (itunes quicktime volume up and down) starts popping and mute completely until I reboot ! And then again when I play it from the timeline same problem,
although I do some modifications to re render the audio.
I uninstalled fcp and reinstalled it.
I trashed the preferences.
I removed audio hijack and the hijack.ape from input managers folder.
I reset the Pram.
I set all the settings for low/faster performance.
I closed all the application to free Ram.
I trashed all the render files on all locations (internal HD and external).
I moved out Audio and video Plugins, to make fcp light.
But no luck.
Please note that at the time of this problem happened, I wasn't installing nor changing anything,
As I was busy in exporting the whole 15 sequences from the same project. I joined some sequences but not this problematic one.
I am on a macbook aluminum 2.0 4 gb ram.
My External HD has 3 partions, 2 Mac and 1 Win Formatted.
Privileges are ok.
I looked throughout the forum but I couldn't see anything.
thanks in advance.

Thanks for the reply and tip. Can't remember what happened with fade out, I think simply didn't apply and it re looped the last frames.
I "solved" the problem by making a new sequence and partially remaking it from scratch.
Then i vaguely copied and pasted from old sequence as copying and paste the whole sequence content onto the new sequence didn't work either !
However this popping noise already happened to me before.
Then, when I was able to join all sequences on a sane quicktime mov, iDVD cut off the audio at one point, I re-exported the video_ts and again iDVD at the same point cut off the audio. I checked the quicktime mov tracks and everything was fine, I also started the iDVD project from scratch as when iDVD tells you that he can update the file for you, he then messes up all the time the Chapters as he simply can't handle this function (aka bug !). I mean it's been a nightmare, still is.
However this iDVD bug is another topic, I would like to keep this post open as it the initial problem has no official solution yet. Could be also useful to somebody else, and also, I am very curious what's the cause, and if it can be fixed properly and faster. If it could happen to me again I don't want to play with timeline.
Thanks again for your reply.

Record Video+external audio+system audio

I need to record a movie with:
- Input from my firewire Camcorder
- Input from my external audio interface
- Input from GarageBand output
Till now I just find two ways of doing it:
1.
- Record audio in GarageBand and video in Quicktime at the same time
- Sync both recordings (with Quicktime or ImovieHD)
2.
- Open a Quicktime movie recording
- Start a screen video capture applicaton (with option to record system audio) and select the quicktime window to record
- Start recording
- Go to GarageBand and start playing
- Switch to Quicktime screen and realy start my recording
- Trim the unwanted initial video recorded.
Unfortnately both workflows are just tricks to do something that is no directly achieved by the applications. In the end it takes double the time to record a movie than it should take.
Is there any way to record with Quicktime a movie and at the same time both internal and external audio?
Is there another application to do it? I have search many applications and it seems that only screencapture apps can record internal sound. I have heard of wirecast but is too expensive (400$).

Although the application seems very interesting how can it help me since it does not record video?
I have no problem in recording audio in GarageBand, the problem is recording in sync audio and video so I don't have later to mix and sync both flows.
Maybe my question is not clear.

My system audio is being relayed to the people I talk to on VoIPs despite my having headphones.

When I use Skype or Teamspeak, the system audio on my computer is rellayed to them. For example, if I take a screenshot they will hear the shutter noise or if I play a video in the background they will hear the audio. I have headphones on, so they aren't receiving echos from the in-built mic and speakers, and in the case of Teamspeak it only happens when I open my mic to speak. I couldn't find any solutions for Macs.

OK, what you should do is download the updates on another machine and burn them to a disc. Start at this link http://support.apple.com/downloads/#leopard for downloads and find, among other things, the 10.5.8 combo updater that works on PPC machines, plus security, QuickTime and other updates. Going from 10.5.1 to 10.5.8, there will probably be a bunch of things that you should install. Being off the internet with the machine, you can't have Software Update sort it out, so something might get missed, unfortunately.
My suggestion is this: if it looks like you might need a download, get it onto that disc.

10.6.2, iShowU 1.75, Soundflower 1.5.1 are not compatible - no system audio

Ever since upgrading to 10.6.2, the system audio features of ishowu no longer function. soundflower works properly but it seems that 10.6.2 does not let other applications switch/utilize soundflower in their apps. I was on a troubleshooting call with ishowu personnel and the problem was narrowed down to the Snow Leopard. All worked well in Leopard and Tiger but now problems. Apple is really going downhill with the launch with many issues.

Thanks. I had tried that previously and its not a soundflower problem. It seems that the new version of Snow Leopard does not provide the switch to allow 3rd party software to communicate with the sound system preferences. This was not a problem with earlier versions of Mac OS and seems to be a bug that was introduced with Snow Leopard. Mac will only survive if it moves forward with max compatibility with 3rd party software producers.

Third-party NTFS software interferes with the Apple NTFS drivers, which control whether you can see the Bootcamp partition in the Startup Disk option. As a test, can you uninstall all third-party NTFS software and check System Preferences -> Startup Disk?

Entire System Audio mutes randomly while working in Premiere

Hi everyone
Just recently switched over to Premiere Pro CS6 at my office. I'm an editor for a web video production company and so far I've been having quite a few problems with Premiere.
The biggest issue is that randomly, maybe 10 times a day, the audio for my entire system will drop out while editing in Premiere. At first I was resorting to doing full restarts of my computer and the problem would fix itself, but now I've discovered that if I go into "Activity Monitor," search for "coreaudiod" and then force restart that activity, the audio will reset itself for the system, but not Premiere. I still have to then restart premiere to get the audio working again in my project.
I've seen other people mention similar issues but I have yet to find a solution. Can anyone help? Thanks so much.
Here are my computer specs:
iMac
27-inch, Mid 2011
Processor 3.1 GHz Intel Core i5
Memory 8 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6970M 1024 MB
Software Mac OS X Lion 10.7.5 (11G63b)
Adobe Premiere Pro CS6
v. 6.0.2

I've worked on two projects so far and it's happened both times. The first project was using ProRes source footage and then outside video assets were brought in that were H264.
Now I'm working on a project that is using Canon DSLR H.264 native footage and video assets that are in H264 and a few that are XDCAM EX.
Also using many still images but it seems as though it will happen randomly when I load a video clip into the Source window. The video clip will play with audio in the source monitor, but then when I bring it into the timeline this is when the entire system audio will drop out and mute entirely.

Satellite L500-1ek - setup system always starts with 800x600

I have new Satellite L500-1ek notebook with Windows 7.
Whatever screen resolution I setup system always starts with 800x600. And not only after restart but even when I logout my profile and login again.
More: I use also external monitor. I can have mirror of my laptop screen on the monitor or only display on monitor but whatever I do I cannot have extended screen.
When I try to set it up I'm simply ignored by driver.
So I tried to install newest driver. I downloaded it from Toshiba site but it never installed saying me that my system did not meet minimum requirements.
What to do now?
Marek

Hi Marek,
> I downloaded it from Toshiba site but it never installed saying me that my system did not meet minimum requirements.
As far as I know your notebook is equipped with Intel graphic card and so you are installing the latest display driver from Toshiba website. Is this right?
Well, I have to say that I had the same issue on my Satellite U400 that is also equipped with Intel graphic card. The solution for this problem was pretty easy: I installed the driver via device manager. There select the graphic card, make a right click on it and select Update Driver. In next windows choose the advanced installation where you can choose the driver directory yourself. After the installation make a restart and thats all! :)

System Audio Capture - Won't Work

Hello all,
I'm trying to capture my system audio and I cannot get Cp8 to do just that. I'm running the most recent version of Cp8 on my MBP OS X 10.9.5. I open a new video demo, with system audio selected, with or without a mic. The mic will capture just fine, no system audio.
I have a request to capture some Skype interview and Tuesday, any help will be great!
Thank you in advance

Hi there,
Have you tried configuring 'Soundflower' audio driver? . Please refer to the below link for more information.

Non-Apple Keyboard: any way to control system audio volume?

I have a non-Apple Keyboard on my new Mini Lion 7.2.1
Is there any way to control system audio volume via the keyboard ?

Well. I can do this. But just because, on my Apple keyboard, there are the keys that do the job. There's a key to mute, and the keys to adjust low and high the sound. But keyboard shortcuts, I don't think exist. The aren't in keyboard shortcut in Keyboard panel, within System Preferences. The bottom line is that isn't a menu item in Finder for lower sound and higher sound. The only option would be an AppleScript that you save as an applet within Scripts menu (activated in Finder via Script Editor) and you invoke with a shortcut... Well, you can do it, if you open the script Set Output Volume in UI Elements Script folder within Scripts folder. Try it out!

System always starts fsck's at boot and can't start normally.

First of all, let me say that this forum is awesome. I've just started my first real ArchLinux experiment and you guys have helped me out so much already!
Anyway, my system keeps starting fsck's at boot. It then starts counting to 1 minute and 30 seconds, after which it stops the fsck and drops into into emergency mode. I can only boot by passing the "fsck.mode=force" parameter to the kernel from the boot manager.
I copied what I think are the relevant lines from journalctl:

Captivate 8 not picking up System Audio

Good morning,
My partner and I are both using Captivate 8. We are trying to use a Lync meeting to capture audio. It works fine on my computer but not on my partners. It seems all her settings are the same as mine. She used to be able to pick up the system audio but it has stopped working for some reason. I have had her re-boot twice. Anything else we should be checking?

Hi Lasers Edge,
It turned out that the problem was not actually in Captivate but in Lync. The Lync setting default was not using the Logitech Headset but something else that Captivate did not pick up as part of system audio. Had to click on the Speaker icon in my tray at the bottom of my window (application agnostic). Then click on Mixer. There are then choices for Speakers, System Audio, Lync, etc.... Only Speakers has a drop-down arrow. Select your headset instead of the HP or Realtech or what ever is there. This should fix the problem.
PS -- For us, why it was working for several weeks and then stopped turned out to be a Blue Jeans Conferencing upgrade. Each member of the team had the issue on different days over a two week span and it turned out to be the same day we updated Blue Jeans. Hope that helps.
