My songs sound scratchy when used in my iphoto slideshows

I am putting 3 iphoto slideshows along with 2 video clips into idvd as a project. My songs all sound scratchy even though I have turned down the volume on the slideshows. What am I doing wrong???
Help!

Oh, I forgot to add this on... I had an IPOD 60 but it got stolen... I got this IPOD 80 as a replacement. The songs sounded fine on the IPOD 60.

Poor sound quality when using air play

How do I fix poor sound quality when using air play with my Denon receiver?

I am not too sure if this is affected by BT software stack or RF design...
iPhone 3G with FW 2.x provides Cisco VPN as well as Email support for corporate usage. However, it's weird that business man wouldn't want to use BT headset and talk to people... We are not asking about new feature support, like A2DP, but reliable, stable BT connection ONLY!!
I've read that lots folks spent a lot of money on purchasing many different BT headsets and tried to get it work with iPhone 3G. I myself tried: Plantronics 510/815/855, Sony HBH-DS970/980, Nokia BH-903. None of them can work fine with my iPhone 3G ever! And iPhone 3G even cause BH-903 and DS-980 hang up after pairing or finishing call!!
That's why I don't believe it's just a "SPECIAL CASE". How could a product FOR BUSINESS purpose get this kind of basic function problem?
I hope we will find this issue could be resolved completely with new F/W, like Safari crash problem before. Other than this BT IOT problem, iPhone 3G is really the phone/companion could provide complete solution fulfill my personal and business needs.

Callers say my voice sounds muffled when using bluetooth.

I have a motorola bluetooth h710/h715 and as soon as I got the iphone 4, everyone is telling my I sound muffled when using it, compared to my 3gs. Anyone else have this issue?

Can a few of you help me with a test? I have a Jawbone 2 & a Jawbone Icon. Both exhibit a strange behavior with my iPhone 4. If either of these headsets are on, paired & connected AND a call is answered or initiated, things are fine.
When it all goes downhill is in this scenario:
My headset is OFF. I receive or make a call and mid-call, I decide to turn on the headset (which I keep off to save battery). The Jawbone connects and automatically switches the iPhone from PHONE to JAWBONE. This is all normal right? Okay here's the problem. The call quality has static, sounds muffled and the caller tells me I sound like I'm in a tin can. If I then switch back to the phone (through the iPhone page of Sources) and then back again, to the Jawbone, most times--quality is back to normal. Obviously this is not something we all want to be doing. Can anyone do this test with their headset .. any brand and even some of you with Icons? It would be good to know if the culprit is the Bluetooth Headset or the iPhone. Remember, it's important that you make a call with your Bluetooth headset in the OFF position and then turn it on mid-call to use it.

Do you have a question?

TS3742 I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto.

I have an iMac 24" system. I just recently installed MAC OS X 10.7.4 (Lion) on my system. Since doing so, my system consistently hangs. Particularly when using iMovie and iPhoto. I have to power off my system to get it running again. Any suggestions on what I can do to address this situation.

I would first reset the SMC:
Shut down and unplug the Mac.
Keep the Mac unplugged for at least fifteen seconds.
Plug the Mac back in and do not turn it back on for at least five seconds.
Press the power button to turn the Mac back on.
Then I would reset the PRAM by rebooting the iMac while simultaneously holding the Command-Option-P-R keys until the machine restarts a second time.
Let us know if these procedures don't solve the problems.
Hope this helps

SOund problem when using Wi-fi

I have problems with the audio when using wifi... electric disturbance like sound(hiccups) when hearing songs or watching videos...
when wifi is turned off no problems....
whats the solution for this ? can installing any driver solve the problem?
just purchased the lap .... please reply fast

Seems to me like a case of a dying headphone jack.
Try playing with the jack (not the iPhone) while playing music, see if it actually causes the "in-out" thing.
If it did, and you are still under warranty, take it to Apple and they'll hopefully give you a replacement.
I put the iPhone in my pocket, and so far I have killed 3 iPhone headphones and 2 Shure ones this way. I moved to much more expensive Shure's as I thought they would be harder to break and while they lasted longer, they still died.
I'd recommend avoiding pressure on jack as much as possible.

Sound distortion when using hdmi cable

HP G62 notebook pc(Laptop) windows 7
I have sound distortion when i connect laptop to pc using HDMI cable, happens after 10 minutes then sound is ok again then 10 minutes later sound distortion again. Sound on laptop is ok. Not HDMI cable because used other laptops and its works fine.

I'm having this issue as well. Just posting to let people know there is more than one person with this issue. I have a pavilion dv5 laptop

Sound leak when using unsigned

I've generated a simple test case which should make this pretty straightforward. I'm using Linux Ubuntu 11.04 with pulseaudio, if it makes any difference.
Basically, I generate a very simple tonal sound for the musical note A3 using Java's java.sound.sampled APIs, and Clip to open and play it.
That's all well and good, but to avoid leaking sound resources, I have to listen to the Clip (or Line) for a STOP event, and then close it. That's fine too. If I play two sounds at the same time and do this, it works fine, too...
unless the sound encoding is unsigned. For some reason, switching it from signed to unsigned (and translating the tonal wave appropriately) makes me only able to close one of the Lines, and the other one goes rogue.
Here's my code:

                         if (event.getType() == Type.STOP) event.getLine().close();
     }A few modifications you can make to see what I'm talking about:
Line 21, change signed to true, and everything works great.
Line 92, assuming signed is false, comment out this line, where I close the stream, and re-run. You will observe 2 Stop events. Enable it again and you will observe only 1 Stop event.
Am I doing something wrong, or is Java's sound system just that deplorable?

I dropped it down to 8000, but it still does the same thing for me. II didn't say it would - just that 80,000 seemed a very high sample rate. Unless you are playing sound to bats using hardware much better than I am then anything higher than a sample rate of 44 KHz is a waste of time. At my age the highest frequency I can hear is about 8 KHz so any sample rate much above 16 KHz is too high.
Makes sense.
have noticed varying behaviors.
I'm fairly new to this sound stuff, and at this point I'm just trying to get it to work. Get what to work? You have not really described, or a least I have not understood, exactly what you are trying to do. You have a clip of sound you are trying to play more than once but you are trying to "avoid leaking sound resources". Can you explain what you mean by this and why you think it necessary; a reference to some Java sound documentation would maybe help us understand.
Well, here's the sound documentation that I'm basing my code off of: http://download.oracle.com/javase/1.5.0/docs/guide/sound/programmer_guide/chapter4.html (and chapter 3)
Basically, my program has a play button that will play a sound that the user has loaded in (complex encodings or formats are not a concern currently). I need to be able to figure out how to handle the user clicking on the button multiple times. I would at least expect an average system to be able to play the sound twice concurrently (overlapping). Maybe I just have the wrong concept when I talk about "sound resources", but it seems like I run into problems down the road, like on my computer, after I've played the sound 30 times, it starts erroring, or if I try to play the sound twice, and then once more after they're done, it causes the application to hang. To me, this seems like it's looking for available lines, and just plum running out, or choosing a line it thinks is available, and hitting a wall. Idunno.
I have a .wav file that uses PCI Unsigned 8000 Hz that was exhibiting this problem. I don't think the '.wav' file was not exhibiting the problem I think your code is/was .
Fair enough. It's easier to fix the code then to expect to have certain types of wavs.
Ultimately it leads to the application hanging entirely,
I would be interested in seeing an SSCCE ( http://pscode.org/sscce.html ) that exhibits this since I have never met it.
I think it would be wise to deal with one problem at a time for now. The program that exhibits it is large and would be time-consuming to simplify. I figure the problems are interrelated, so if we can fix the current problem, the apparent freezing issue should resolve itself as well. If not, then I can make an SSCCE for that.
and I have to forcibly quit the JVM. Being able to close all sounds completely curtails that "feature", but it's apparently not an option for unsigned encodings.Since the difference between the two is just a toggle of one bit I don't really believe that this is a signed/unsigned problem. I believe there is something more fundamental to explain the problem. I expected as much. It's always nice to be able to fix one's own code/thinking than to hit a roadblock with the limitations of an API.
>>
Plus, your exception doesn't sound that desirable either.I didn't say it was desirable - I was just saying what I observed. My exception seems logical since the line I was trying to open was already open so a LineUnavailableException makes sense.I suppose so, yes. And I'm guessing your system is more than capable of playing two lines concurrently, if done correctly.
I suppose the problem that you're seeing (and probably mine, too) is that it's trying to recycle the Line (just a guess - I could be completely off). For whatever reason, mine lets me play the recycled line twice, but yours doesn't. Both ways cause issues.
I suppose this tells me that if I want to play another sound concurrently, I need another line, not a recycled one. Does that seem about right? If so, how might I go about doing that?
If not, perhaps I'm a little thick and need some hints.
In short, the problem is I would like to be able to play two sounds concurrently (seems like a reasonable enough request), but either I can't using my current code code (as you've seen), or it causes other issues (my side). So I'd like to know how to fix the code to enable this.
Greatly appreciated.

Microphone sounds low when using face time

For some reason people complain when i use my microphone on my display when using Face Time

When i record on quick time it is fine you think its a face time issue ?

Skype I mean.

No sound when on Facebook app. Sound ok when using I pad otherwise

How can I get the audio to work when using Facebook app? The audio is ok when using the iPad otherwise. I already tried to fix by deleting the app and reinstalling also tried to reboot. No luck. Please help. I had been using Facebook previously without any problem.

Hi,
Try a clean installation of the flash plugin/activeX as follows.
First, download the Flash uninstall utility on the link below and save it to your Downloads folder.
Flash Player Uninstaller.
When the download has completed, close all browser windows, open your Download folder and run the uninstaller. After this has completed, restart the notebook.
When windows has reloaded, download and install the latest version of Adobe Flash. Note: You may want to deselect the option to include McAfee Security Scan Plus before downloading.
When the installation has completed, restart the notebook again nefore checking if you now have audio on the internet.

Songs are scratchy when i upgraded to 7.0...

i upgraded to 7.0 and it automatically put every music file i have onto itunes (from windows media etc). Now, many, i don't know if all, my songs are scratchy and skip (1-3 secs). is it something with 7.0, my computer or what?
dell Windows XP 3200+ athlon processor, 160 gigs, 2.4 GHz (im not very technical read it in manuel)
dell Windows XP 3200+ athlon processor, 160 gigs, 2.4 GHz (im not very technical read it in manuel)

Pop up your task manager and look at CPU usage. iTunes 7 pegs the CPU at 100% doing just about anything. I had to downgrade back to verson 6.05 to make it usable again.
I'm waiting for an update to 7.0. Save yourself a lot of frustration and do the same.
7.0 runs great under MacOSX, so it seems to be poor XP coding to blame.
Good luck!

Using Keynote and iPhoto slideshow together

Computer: 12" Powerbook G4, 1.5ghz
Display: 23" Apple Cinema Display (1920x1200)
Software: OSX 10.4.9, Keynote 2, iPhoto 6
Hi everyone! Above are the specs for the project I'm working on and here's the problem I'm having:
I am trying to create a makeshift kiosk display for an upcoming event using slides in Keynote and a picture slideshow in iPhoto. I'm planning on running it off my Powerbook to my 23" Cinema Display.
I'm using Keynote for the presentation content because of the motion effects (transitions, build-ins, etc.) and iPhoto for the image slideshow because of the Ken Burns effect (which I don't believe Keynote has). Both look great running seperately, however when this is being displayed at the show, I'll need both to run back to back automatically, without having to manually switch back and forth between applications.
I have both the Keynote presentation and the iPhoto slideshow displaying at 1920x1200. I've tried exporting the iPhoto slideshow to Quicktime, but it won't export any higher than 640x480. Does anyone have any ideas on how I can make this work? I won't be able to operate the computer when this is running, so I really need to find a way to make everything run seamlessly while keeping the high resolution of the 1920x1200 monitor.
Any advice would be GREATLY appreciated!
Thanks,

iMovie is a DV editing app and the final results would still make a 640X480 file.
I would change a few things to make everything work together:
First is the display resolution. You want the 23 inches to be used so just reduce the display preferences to try and match your QuickTime file. 800X600 sounds about right but larger will still work as H.264 Video scales up in size very nicely.
This would force you to "reduce" the dimensions of the Keynote file but that shouldn't be much of an issue.
QuickTime Pro could also be used to "change" the dimensions of the 640X480 file. Again, H.264 scales up in size and would look pretty good at even double size.
The goal is to have them both at the same dimension and then match the monitor resolution.
Easier to change the display than the files.

2 Apple TV's and no sound output when using AirPlay/mirroring?

Hi,
Bought my first apple tv and when air mirroring was able to go to my system preferences and choose sound output for it and it worked beautifully when I wanted to play a movie on my computer and send it to the TV. Bought a second apple tv for the bedroom, both are connected over wifi. Using Mountain Lion on my iMac. Now it won't play any sound on either and will not let me choose which apple tv in system preferences - sound. Any help would be appreciated
Sue
I have tried turning Apple TV on first, then choosing sound output before turning on air mirroring. Problem is it won't let me choose, stays on internal speakers.
This fix won't work for me.

Might I recommend the following sample code instead?

Having 2 level of sound volume when using internal speakers or headset

Hello to everyone.
I have a HP Probook 4530s which I bought september 2011. I have never had any hardware difficuallty with my system and I'm very happy with it.
Yesterday, I updated a few of my laptop drivers sush as LAN, Pointing Devices, HP Power Assistant and finaly sound card driver which is an IDT High Definition Audio CODEC all recomended by HP support Assistant Program.
I tried to test the functionallity of my system after downloading and installing these new updates to see if any of them have any problem. That's when I noticed that my sound experience have been altered. Previously when I was using my system with a pair of headphones and my sound level was for example 70% and when I disconnect the headphones the sound level would suddenly jump to the value that I was using last time without headphones for example 25%.
As of yesterday after updating the drivers, I can't have that feature.
Please HELP, and thanks in advanced.

Hi Shahramb,
Your ProBook 4530s is a commercial product and to get your issue more exposure I would suggest posting in the commercial forums. Here is a link to the Commercial Notebook forum.
