External sound problem

My MacBookPro 15', Lion, external sound was working fine until I attempted to use my Duet (with updated drivers) for monitoring my sound. I was not successful. However, now I cannot get sound from my external speakers. I have checked the external sound with my iPhone and it works OK.
When I disconnect the Duet, I have for Input Internal Microphone and Line In. For Output I have Internal Speakers. The Internal Speakers work but when I connect the external speakers no sound. Any advice to solve my problem would be appreciated.

Hi David,
Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions...
Move these files to the desktop...
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Library/Preferences/com.apple.soundpref.plist
You'll need to trash the original of this second one, since moving just copies it.
reboot, set up Sound again.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Beats audio android app external sound problem.

Hey guys,
Recently i downloaded the Beats Audio Android app for my Optimus 2. At first it worked fine, the external sound was good, as well as the headphone output. Very shortly after the external sound became very fuzzy and loud, with the headphone output still working perfectly. The only feature that would play sound without fuzz was speakerphone while in a call. I decided to factory default my phone thinking it would fix the problem, i was already going to do it anyway. Come to find out everything got wiped including beats audio, but the same old external sound problems persisted. I'm not sure how to fix it and it is very annoying and sometimes randomly goes off. Help is greatly appreciated, thanks.

Maybe it has something to do with the master volume? Although i'm not sure how to access that either..

Hello,
I see that you are having trouble with the beats audio app on your phone. I would suggest that you post your issue here as well for assistance. The link will take you to the android forum for your phone.

External Sound Card Problems

I've been enjoying my HP dv7-1025nr for the past few months with no problems. I recently decided to get into home audio recording and purchased an M-audio profire 2626 external sound card which connects through firewire. I've yet to get any sound from my computer through the device. I have downloaded and installed all the latest drivers several times (both for the profire and every other device on my computer). I've also updated the flash bios for my hp (which i'm still trying to figure out why there's no "advanced" tab in the menu...other users have resolved irq issues this way and it's not even an option for me). I have reinstalled my OS (several times). The M-audio tech support suggested purchasing a dedicated firewire card with a TI chipset to solve previous connectivity issues, so I got a Siig 2-port ExpressCard. My current problem is that even with the profire set as my default playback device, there seems to be a problem where windows is unable to send it any sounds. If I try to use itunes or windows media player, the timer won't even start when i press play. Everything works perfectly when i change the windows default playback device to anything else (laptop speakers, spdif out or nvidia hdmi out). I'm confident that everything on the profire's end is working correctly and there must be some form of harware or software conflict (windows services or otherwise). Device manager doesn't show and irq conflicts but i'm wondering if there could still be one. Windows is recognizing the device and the m-audio control utility is working. The profire also works perfectly through my other computer (a gateway laptop running xp). I have spent 2 weeks trouble shooting this problem and have come to the conclusion it cannot be fixed through normal trobleshooting means. I need a programmer to help me out with this one. Please help.

I have a problem with the external sound of my ipod, when I take the headphones the music keeps playing and the ipod recognizes still have a headset connected. how do I get external sound out?

I have a problem with the external sound of my iPod, when I take the headphones the music keeps playing and the ipod recognizes still have a headset connected. how do I get external sound out?

- Try insering and removing the headphone plug a dozen times or so.
- Try cleaning out the headphone jack in the iPod.
- Resett he iPod. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restoe to factory defaults/new iPod
If yu still have the problem that indicates a hardware problem, likely a bad headphone jack. Yu can make an appointment at the Genius Bar of an Apple store to confirm.
If not underwarranty Apple will only exchange your iPod for a refurbished one for:

Desperately need some help!! iTunes/Quicktime/iChat/Sound problems....

So, yesterday, I was online, on google video, and when I pressed play on the video, there was no sound, but the video worked...the same was true on every video site i checked. My computer volume was at max, and I even tested the speakers to make sure they were on, and they indeed were.
I thought that was odd...but then the problems really started.....
After that, I clicked on my iChat icon. It bounced once, and did not open. The same thing happened when I clicked on iTunes. 1 bounce, and then nothing. I checked to make sure all of my iTunes mp3 files were on my computer....they indeed are all still here, bit nothing I can do opens iTunes. I've run disc utilities, and disc repair...according to that, everything is peachy-keen on my computer.....but iChat and iTunes STILL will not open, and there is still no sound on anything.
Now, i'm leaning towards the archive and install option....or even just backing up what I want to save, wiping the drive, and starting from scratch.....but i'd really like to not have that happen.
(and, as a side question, if all I want to save are images, several documents, and many mp3 files, would everything be okay if I just backed them up on an external drive, and then loaded them back on to my computer after reinstalling OS X?)
Sorry about the length of this, but I am at my wit's end, and I have no idea what to do.

by third-party, do you mean things I installed that are not manufactured by mac? If that is the case, I have microsoft office, Smart Music, Flip4mac, and Senuti.
I got rid of Flip4Mac to see if that affected my sound problems, but it did not. So, as of now, my problem remains the same...

Sound problems on ProBook 6550b, running on Win 7 Pro x32bit..

I have been getting very similar sound problems on my notebook as posted by most: internal speakers work on original Audio HD drivers, but there is no sound when I connect external speakers or headphones. I up-graded the audio drivers to IDT HD Audio and I get sound coming from external speakers or headphones, but nothing from internal speakers.
I have tried everything from reporting the problem on public forums, live help, and done this or that, but nothing changes. It's so very clear to me that it has to do with audio drivers, which don't seem to work appropriately to cover all aspects of sound output.
I also, often, get this loud, weird, irritating noise and a frozen PC when I am playing music with the notebook, while on the internet. The best I do is not to do both at the same time. I have seen similar problems on blogs, but tangible solutions are NOT offered!!!! Please help...

Audio Switching coudl be due to several reason. if you have tried latest audio drivers and latest Video drivers from hp.com, i suggest you to get audio board replaced for your computer.
Hope it helps.

Any resolution to the sound problem?

I have been having the same sound problem with my Mid 2010 Mac Pro tower ever since I got it. I have been in touch with Apple and have been told that they are familiar with the problem, but that they are still working on a fix. The problem is that I have external speakers, and every time I shut down and then start up again, I have to go to preferences and physically change the sound output to go to the speakers. I have also been tole that the Mac is supposed to sense the external speakers and go directly to them.
Is there anybody else out there with this problem, and has been able to resolve it?
Thank you.

I have a 2010 Mac Pro and use the stereo line out jack in the back of my machine for my speakers with no problem. I don't recall any problems setting it up. But check the Audio MIDI Setup (in your utilities folder) to see if you can set it from there (should be able to). Not sure why the preference wouldn't stick. And I don't believe there is automatic detection of an attached sound output device where the sound preference switches to that (unless maybe the front jack which I never use).

External Sound Jack

I have a Satellite -P205D- S7438. For some unknown reason, anytime I plug in my head-phones, or external speakers. I can not hear any sound. Does anyone have an Idea on how to fix this??? I have even tried updateing Driver's, did not fix the problem.

QT 7 sound problem

I have just upgraded to OS LION. My old QT type movies would not play sound with the new upgraded "10.1" quicktime Version. I have download Flip4Mac and Perian but no success..... Need help Please

Funny you should bring this up. I just had a 'no audio' problem with my TiBook that just appeared overnight for no apparent reason. I have a FireWave external sound device and the settings that worked fine the night before just stopped working the next morning. I could only use one setting and that setting only gave me stereo sound from two speakers. All the other settings produced no audio even when trying the speaker tests.
I ran through the whole nine yards yesterday and nothing worked, so, I finally just unplugged/re-plugged the FireWire cable and everything works again. Strange how that worked when numerous restarts failed. Too bad you can't just disconnect/reconnect the internal sound device on a Computer. Something weird going on here...

Sound Problems on iPad: how to fix, easy [video]

Hi dear iPad user,
Most people will, eventually, have sound problems: the cause can be complex as a 'miss-behaved' app that messes the sound engine or as simple as the iPad being forgotten on Mute/Volume Down.
I used to help family and friends to fix their iPads' sound problems by sending them 'text' instruction steps... lots of times they ended up calling me on the phone...
So I made a video (short: 1m40s):
https://www.youtube.com/watch?v=FjBP-Ncj_fE
It shows:
how to unmute the sound (even if the side-switch locks the rotation of the screen)
how to put volume up
how to close all the apps (in the case there is an App messing with the sound system)
how to reboot the iPad (ultimatelly fixes hard cases of messed sound system)
What it won't fix: if you have a hardware problem...
If you do all the steps and you get NO SOUND AT ALL, please, try also checking if you car listen sounds using a HEADPHONE (you know are working conditions). If you can listen to sounds in the headphone but no sound at all in the iPad's built in speaker, well, there might be a hardware problem and you should look for help on an Apple Retail Store or other official technical support available at your location.
Hope this helps!
Everson.

UPDATE: fixing iPad Sound after iOS 7
http://youtu.be/SDf1LDcE95Q
(1min 36sec)
It covers the basics:
checking side-switch / mute / "Control Center"
volume all up
...and also the worst cases:
closing all apps (for rare cases when a single app might render the sound system instable)
rebooting the iPad
So, don't get desparete: try the things in the video.
There are people who reported having forgotten an audio-bluetooth connection activated with a turned-off sound-system or speakers... or forgot Air-Play turned on... so be sure you disengage bluetooth and/or airplay.
On the 'hardware side', dirty dock connector (30 pin) can make the iPad 'think' it is connected to external audio - if so, cleaning it with a dry toothbrush can fix. Also, moisture in the headphones connector can make the iPad switch to 'headphones' even without headphones connected, making it silent: check if you can hear things with headphones plugged in - if so, try gently inserting and removing headphones a few times and check if you get sound back to iPad's speakers alone.
Good luck to everybody! Audio problems are quite common - fontunately they are easy to fix.

Pismo Sound Problems after Sleep in Tiger

Hi all. New to the forums and returning to Macs after years of cursing Bill Gates. Picked up a Powerbook Pismo from a friend and have been having some fun with it, but I have one problem I can't solve. I replaced the hard drive (saved the old one) and installed Tiger and 1GB of memory on the machine. All seemed well until I noticed that the sound would not work sometimes after sleeping. The sound will usually return with a reboot, but sometimes I'll have to actually turn the machine off, and clear the PRAM to get the sound to come back. Sometimes, the volume and screen controls will both not work at all (pop up doesn't even appear when the keys are pressed), sometimes it's just that the sound doesn't work, but everything looks right on the screen. I've also had the sound and screen buttons not work only to have pop ups suddenly appear and the adjustments happen several minutes after I pressed the keys. So far I've tried:
Clearing the PRAM
Checked the Pram Battery (ok)
Reinstalled Tiger (Still loses sound)
Downgraded to 10.3 (problem persists, and seems worse)
In system information on Tiger it says "there was an error when retrieving that information" when you click on the sound hardware.
The machine is a 500mhz Pismo with a 48gig drive and 1 gig of Memory (133mhz, would that cause this sort of problem?)
I have not tried going back to OS9 to see if the disappearing sound resolves as I don't currently have an OS9 disk.
This sure seems like a software problem, but I'm starting to wonder. I really like this machine and want to get it to work! Help!

Maxstang, welcome to Apple Discussions.
Did you repair permissions after you installed Tiger? Have you updated Tiger to 10.4.11?
Here's the Sound troubleshooting info in the Pismo Service Manual.
No sound from speaker(s)
1. Verify mute mode is not enabled (F6 on the keyboard).
2. Check the volume setting in the Sound control panel.
3. Verify no external speakers or headphones are plugged in.
4. Reset PRAM.
5. Make sure speaker cable is plugged into sound card.
6. Replace sound card.
7. Replace speakers (part of the top case).
8. Replace I/O logic board
Startup sound is heard, then no sound from speaker(s)
1. Remove sound preferences from System Folder, reset PRAM,
then restart.
2. Perform clean installation of system software.
Had the Pismo previously had OS X installed. There's a firmware update (Boot ROM version 4.1.8) that should be installed prior to installing OS X. However, when I got my Pismo with Tiger installed, the firmware was not updated (have since updated). However, I don't think this could be the cause of your problem, since I had no sound problems when the update was not installed.
The PC133 RAM (which runs at 100MHz) should not be the problem. I have PC133 RAM in my Pismo.
Since you replaced the HD, could you have disturbed the connection to the Sound Card. The Sound Card is located to the upper-right of the HD. Here's a helpful laptop site.

TS2090 Apple TV mirroring - sound problem. Tried everything. It's ****.

I'm feeling totally exasperated. I've tried every 'solution' to the inherent Apple TV mirroring sound problem. Why don't Apple just fix it?? All I want to do is be able to view my computer video with sound when i want to. I don't feel that I should have to spend up to and over an hour trying repeated combinations of turning things on and off, entering code into Terminal, etc. EVERY TIME THAT I TRY TO MIRROR THROUGH APPLE TV. It's ridiculous, aside from the cost of buying the unit, I had to upload Mountain Lion despite the fact that my new (Early 2012) imac should have been on spec. That took hours and it still doesn't work. Very dissappointed, Apple have lost my brand loyalty for such an obviously fixable thing. ( I don't think that they read these comments). hope this makes you think twice before buying. Yours, m

I found a fix for this problem thanks to a friend of mine who I can only assume did a little research online!!
The problem I had was having AirParrot once installed, and after the recent 10.9.2 update, the third party app messed up the way Mirroring was working..
Here is the fix:
1. Open Terminal in /Applications/Utilities.
2. Run these commands respectively:
sudo rm -rf /System/Library/Extensions/APExtFramebuffer.kext
sudo rm -rf /System/Library/Extensions/AirParrotDriver.kext
sudo rm -rf /Library/Extensions/APExtFramebuffer.kext
sudo rm -rf /Library/Extensions/AirParrotDriver.kext
This will uninstall kernel extensions related to AirParrot. Other solutions around the web being posted are missing the extensions within /Library/Extensions.
3. Enter your administrative password when prompted.
4. Restart your computer.
I tried it once again and it worked like a dream!!!
Here is the article for reference:

Many Thanks for all who tried to help, and especially Wasim!!
Hope this helps anyone with the same problem in the future!!

Sound Problem Plus Memory Problem

I've also posted this same issue at the EVGA website with no help what so ever yet. Also if it's ok I'm having the above mentioned memory problem that it probable not related but if anyone does have good input I would love to hear. Hope this doesn't break any rules, didn't see anything in the listed rules thread. So here it goes.
Ok I'm having a few minor but very perplexing and annoying problems. I have recently built a new rig to include the following.
Windows 7 64 bit Home Edition
EVGA P55 FTW Intel P55 Socket LGA56
Intel Core i5-750 2.66Ghz 8M LGA56 CPU
Corsair Dominator 4GB DDR3 PC2800 (2 x 2 GB sticks)
Ultra LSP750 750w Power Supply
Seagate TB Serial ATA HD 7200/32MB
Cooler Master HAF 932 Full Tower Black Case
Galaxy GeForce GTS 250 52MB PCIe x2 (SLI Setup)
BFG - NVIDIA GeForce 9800 GT GB GDDR3 PCI Express Graphics Card (Physx Setup)
PROBLEM ONE:
This one I had a lot less that I was able to actually try because it just confused the crap out of me. So I started by going to test my sound. I'm running an optical cable from the on board sound port to back of my sony surround sound system. I get sound from my left and right channel but nothing from the center, rears or sub. So figure no biggie just need to change the configuration from 2 speaker stereo to 5. surround sound. Guess what... the option isn't there? WTF? A sound card with an optical port with no 5. support? So went online found the drivers for the sound on the mother board and tried reinstalling thinking maybe somthing was wrong with the drivers on the CD. Well it still didn't work. So I figured what ever, I got an external sound card that I know works with Windows 7 since it was on other desktop and hooked it up. Its a Creative - Sound Blaster X-Fi Surround 5. External USB Sound Card. Well it installs fine and I go to test it. Yep you guessed it! Still only sound from the left channel and the right channel with no option for surround sound. So I was able to find updated drivers for that and ran em. Well now I have an option for Surround sound with side speakers only no rear. Oh but it doesn't really matter because the left and right channel are still the only ones able to produce sound. And yes the speakers work I turned on my X-Box 360 hooked up to the same speakers and LCD tv and played COD4 with full sound working fine. So something else has to be happening I just have no idea.
PROBLEM TWO:
The second problem was with the memory. Everything booted fine but it initial only detected 2 GB. By the way I had them installed in slots and 3. So I shut down and popped em out checked the copper connectors everything looked fine and reseated the chi
ps.
This time during the boot up I checked the BIOS. It saw all 4 GBs of memory. Continued into Windows. Windows now saw all 4 but only .99 GB was available. Now the only other time I've seen anything like this was with on board video sharing the memory, and even then it wasn't half of the systems total memory. I then tried shutting down and putting the chips in 2 and 4 just see what would happen. Well I got an EA post error on the LED, couldn't even boot. So I figured o'well power down completely and tried to run the memory in 2 and 3 to run it out of dual channel. I was able to boot but still had the same issue. .99 GB available and still saw all 4. At this point it was just getting silly so I figured ok I'll download the new BIOS with my laptop, burned it to a CD. Booted the desktop and ran the BIOS flash. Update seemed work fine, honestly the BIOS didn't look much different and I didn't take note of the previous version before I did it so I can only assume it worked. However it did not fix my problem. So I'm still stuck at windows seeing 4 GB of memory with only .99 available.
Anyway... I'll keep trying to get this working and hunting around online, but I'm really hoping you all have some ideas. I'll be trying to call EVGA today for some help too and possibly Corsair. Thanks in advance for the help!

Hello,
cannot help with the sound problem.
For memory, I've got almost the same thing but with 4 sticks of 2gb and only 2 detected on an ASUS P7P55D deluxe.
Bios was my issue but I needed to do this (but with pairs of sticks instead of sticks) after the bios update to finally get my 8gb under windows:
Make a clear cmos. Then boot the computer with only one stick of ram in the port .
If everything is fine, turn off and add the other port of the same color for dual channel.
If it does not boot with the 2 sticks in the port of the good color, try to switch ports again. Maybe one stick is dead?

External sounds quit working

I have reseached this and find that many have asked questions about sounds on their Ipod touch. My 8G external sound has quitl. I just downloaded the latest update and now I have no sound when I type, unlock or play games. I do have sound using headphones. The Ipod is 8 months old. Is there a fix or goodwill warantee? If I called an Apple Store would they know about a fix. How would I launch an official complaint. Why, if so many of us have this problem has Apple ignored it? I see questions as far back as 2007 with this problem. Sooo many questions, I know, but I am so new to the Apple scene and over 60 years old.

Have you tried of the basic R's of troubleshooting yet to rule out a software issue?

External sound not working

I think it started after I put headphones in. But I cannot hear ringtones, music, speakerphone, ect. I have obviously checked volume, put in safe mode, took out battery, hard reset, nothing has worked. not much help on the internet either. Sounds like I am going to have to get replacement phone?

I got my Galaxy S4 a week ago and am still trying to learn how to use it. The external sound worked fine then all of a sudden 2 days ago it stopped coming through. SVoice and Robin (voice assistant) don't talk to me, whether Driving Mode is on or off. Klue's message above mentioned the earphones. I did use them once but there's no external sound when the earphones aren't plugged in. (BTW, the earphones don't fit nearly as well as my iPod earphones do. )
I think I probably just hit a button somewhere that turned off the external sound but I can't find what I did. I previously had sound when I was using Wifi and Bluetooth so I don't think that's the problem.
Please help. I wish the User's Manual was more thorough and offered much more info to us than it does. This is my 1st smartphone and need more help than the User's Manual offers.
Thanks.
