Sound from Mac Pro USB speakers fail

Sound from the USB ports on my Mac Pro (Early 2009) fail after a couple of seconds. Sound can still be heard from the Internal Speakers. I have replaced the USB speakers with several types and brands. Problem remains. I can get sound for several second then it quits and can not be restarted.

Try smc and pram reset.
See if everything looks ok in Audio MIDI Setup (in Utilities).

Strange sounds from Mac Pro

Strange clicks going from Mac Pro soon after power up.
It may going from memory cage when temperature of memory is rising.
Any ideas?

Or the graphic card if it has a fan. Or the fans if one is loose.
You should at least for awhile monitor the temperatures with one of the free/shareware utilities. If you push the system, you might even want to boost the fans from their default.
Try running Apple Hardware Test after you check for dust, loose cards. Could it be the PSU?

No Sound from Mac Pro, however, volume icon moves up and down

Hello, I was using my 12 month old Mac Pro last night and it worked fine with sound as normal. When I powered it up today there is no sound coming from my monitor, but the volume icon moves up and down when I press the keys? I've checked in the Preference sound file and everything is set ok? I googled this problem and some people have suggested that there should not be a 'red' light showing in the digital connection on the back? However, I can see a red light, I've tried using my headphones in the front mini-jack and nothing? I disconnected the monitor audio cables restarted the Mac, there was then sound as normal if I used the sound keys. I re-connected the audio cable and it continued to play sound for 5 minutes or so, then stopped working again?

I have a problem with my Powerbook automatically muting. If you read the posts, there seem to be a lot of people having this problem and no one can explain or help.

Speaker sound on Mac pro

After I used the sound from headphone ...
the speaker sound on Mac pro became not working, How I can fix this problem?

Try system preferences and click on SOUND select the OUTPUT tab and make sure Internal Speakers are highlighted... You can always try rebooting the computer or an SMC reset... To do an SMC reset, Power the mac down, Hold Control + Option + Shift... while holding them press power and hold all for 10 seconds. Release and power the mac back on... This should fix it if selecting from system preferences doesn't fix it...

How to delete applications from mac pro?

I think many people struggling at "How to delete appalications from Mac pro ,just because you made some mistakes or curious !" I know it is a bit difficut for people who are new users for the Mac .
If you really don't want them ,you can delete them easily,
As all you know after you download appalications from anywhere ,it could be from apple app store or from other websites. They all can be disspeared if you don't like them .
First , If you installed from apple app store it will be really easily just click at the app on the launchpad, after few seconds all the apps will be all shaking like leaves ,yes they are scared .(No No don't delete me I am helpful !) Ok yes that is a little joke ! so what you can see now there is a small "x" at the top right corner .Can you see them ? just click the "x" And they will gone .
Second step. This is only for you downoaded from other websites , In that case , you just skip first step come to here in order to save you some golden time .
You can delete them from the launchpad , I have tried many times . i tried to drug them in the the trash . But after them all jump back to where they are , So you need to open the Finder ---> click the download -----> find the file which is belong to the app (make sure ) ------->click it -----> drug it into the trash. then you can hear a little sound like you through it into the bin. it is really humanny isn't it ? then go back to the finder again .---->click the application -------> find the icon on there which is you just drag into the trash. do it again . take this one into the trash as well then you will find the icon on the launchpad is disppeared . at the end don't forget to empty your trash After that all job done , it is been deleted ,

No sound from Premiere Pro

I was reviewing a video in the source tab when i realized that I couldn't hear any of the sound from Premiere Pro.
I can see the sound db raising in the sound value bar but I cannot hear anything from Premiere Pro.
I can hear everything outside of Premiere but nothing inside of it.

A little more information:
I'm listening on my headphones when the sound didn't work.
I therefore tried to turn them off and listen over the computers and it worked over the computers speakers.
But it still doesn't work on my headphones. I can hear every other sound than the sound from Premiere on my headphones.
While I hear a song from for example Spotify while I edit in Premiere then I still can't hear anything from Premiere on my headphone(because it is on my computers speakers) but i can still hear everything from Spotify.

Is there a way to record sound from mac ????

using a mbp with snowleopard ... can I record mac output ?
Using microphone is ridicolus and let a lot of noise
Using soundflower I could not hear nothing while recording.
I nedd to hear and record sound outup from my mac like I did on windows... Is it possible without installing 3rd party software ?
And with 3rd softwares ?

I've tried both suggested software but I think I was not so clear.
I need to use sound from mac as an input while I could hear it.
I do not need a software that record sound from mac.
For example... if on windows i set input "wave out mix" instead of "microphone" I could use system sound as input... for example record a lot of error message's sound (PING!) with quicktime pro...
I would do the same thing with macosx...
I am surprised that such a simple thing could not be done with this OS but now I am looking for a 3rd party software that could solve this problem...
Both Audacity and Wiretap can record sound... but not let select me system sound as input.
I need to select system sound as input in order to record it (while I hear it) with every software I want to use... QT pro for example...
Is this so difficult?

No sound from internal or external speakers

Imac 27" mid-2011 running Maverics 10.9.3 I'm not getting any sound from internal or ext. speakers. I can hear the startup sound when booting up.
System Preferences->Sound only shows Digital Out for OUTPUT and Output Volume is maxed and can't be adjusted. Mute is NOT checked.
I've done an SMC and PRAM reset with no change. I've tried multiple times plugging and unplugging the external speaker cable jack.
Any suggestions would be most welcome.

Hey krawfo,
Thanks for using Apple Support Communities.
Looks like you are not getting sound from your speakers. I see you have tried different things to try and resolve this. This article is a good resource for this issue.

Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.

I only get sound from the computer's speakers even though I put in headphones

I have for a while now had the problem that I only get sound from the computer's speakers even though i plug in the headphones, I have rebooted the computer but still the same problem occurs. So i thought there might be someting wrong in the settings, when i open the soundsettings and plug in my headphones nothing happens, usually I believe there should be a text appearing that says that the sound is now going to headphones, am I right? any how, it still just sends the sound out to the speakers and there is no option to send it else where then "soundflower 2ch and soundflower 16ch".
I do have an external sound card, for music recording, that goes through USB, and when i plug that in i get the option to send the sound to that device and also to recive sound and i can also choose if i want to sent it to the computer's speakers. So could it be someting wrong with the headphone jack?

Good day!
Thank you for writing to the Dell Community Forum.
Boot into the System Bios and make sure that Onboard Devices- Integrated Audio is On. Then exit the System Bios saving the change. Once back into Windows, open the Device Manager and make sure that ADI1983 HDA appears under Sound devices. Then re-test the rear green audio jack #4 using headphones. Also, reply to this post with the service tag of the system sent via private message so that I can look into the details of the system and assist you better.
Have a great day ahead.

How do i save files from mac pro to an external hard drive

how do i save files from mac pro to an external hard drive

Your external drive is formatted NTFS which OS X can read from but not write to. You can either install third-party software on the Mac to enable writing to the drive or repartition and reformat the drive for exclusive use with the Mac. If you don't need to move files between a Mac and a PC, then I would recommend the latter solution.
Tuxera NTFS 2012.3.2
NTFS for Mac OS X 9.5.3
To repartition:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select the external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

VFL Speaker sound from both the front speakers while FR sound is not coming out at all.

I have a creative gigaworks s750 connected to a xtreme gamer sound card. The system was working absolutely fine but now it has started behaving very strangely; system is playing back Front Left Speaker sound from both the front speakers while Front Right sound is not coming out at all. If i click the front right speaker in audio console speaker setup wizard, no sound comes. However when i click the front left speaker, sound comes out of both speakers. I counter checked it with playing 5.1 dts movie and muting all the speakers except the front left one from ac3 filter, sound came out of both the front speakers. However when i muted all the channel except the front right, no sound was coming out of front right speaker.

Just want to add another relieved reader of this thread. I had lost the sound to my speakers even though I had sound to headphones. I was convinced it was a damaged headphone jack because I had pushed the headphone plug in harder the last evening when my wife complained that she could still hear the speakers while I listened with the headphones. The next morning--no speaker sound.
I spent a few hours searching the web to see how to disassemble a satellite A505 and get to the jack. But I wasn't even sure I could get a proper replacement jack that fit, and I was concerned that small damage, say to the ribbon connectors could render the computer useless--a large price to pay for just missing audio.
Fortunately, I stumbled onto this thread and I recalled I had put the unit to sleep the night before--something I don't usually do, but I didn't want all the Chrome web sites to have to reload so I just put it to sleep.
When I put it to sleep again and fired it up--Sound! I am so glad to find this solution so I just want to let people know it remains a viable option.
