Sound problem - internal or external speakers

I have a mini and a USB hub (Belkin) with a USB headset (Plantronics) connected to it, and then a display (FujitsuSiemens) with speakers connected to the sound port on the mini.
My problem is that some applications (Safari, RealPLayer, MS Remote Desktop) favors the headset for sound out, others (iTunes, Mail, well most apps actually) chooses the speakers in the display which I'm very pleased with.
System Preferences states sound out in the internal speakers, but obviosly it doesn't really work with som apps so my question is: why, why, why Mr Anderson...
Is it some plist that has gone heywire or do I need to reset some weird PRAM or what ever...

You may need to reset PRAM/NVRAM.
First, check that the jack is clean. Put some alcohol on a plug and insert it a few times. See if that helps.
is your output both digital and analog? If digital, is the red laser light visible in the socket? Do not look directly into the socket when checking.
If all else fails try a PRAM reset:
Reset your computer’s PRAM
A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that Mac OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Immediately press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Continue holding the keys down until the computer restarts, and you hear the startup sound for the second time.
DO NOT HOLD These keys beyond the second startup sound!
Release the keys.
Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.

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.

How to get internal and external speakers playing together?

Hey everyone, I just bought the HP ENVY dv7 with beats audio and I love it! I only have one question that I couldn't seem to get answered anywhere else so I turned to here. Is there a way I can have the compuer's internal speakers (beats audio) and my home stereo speakers (external) playing at the same time? I love how good the beats sound but I also want the surround sound given by the external speakers. So is there a setting I can switch it to so it'll play both? I've tried looking but couldn't find it. Or is there some program/driver like thing I need to download off the interwebs so it'll play both? Thanks in advanced.

Hello Branman,
I understand you want to play your surround sound system while also being able to hear your internal laptop speakers, is that correct? I will be happy to help you.
Unfortunately that will not work, by design whenever you plug in a surround sound system or just a standard set of headphones the system automatically disables the internal speakers. I was not able to come across any legit online software that you can download to make that a possible transition.
Thanks

I have lost all audio on both my internal and external speakers.

I have lost audio on both my internal and external speakers. I have checked the System Preferences when my external speakers are plugged in it is acknowledged. When using internal speakers they are also acknowledged. Sound volume on Preferences is on and fully high. The sound buttons on the keyboard do not work and the sound level is now locked in at full sound and cannot be adjusted using the keys. The System Preferences shows that Mute is now checked and I cannot uncheck it. What should I do to get my sound back both internally and externally?

Repair permissions & restart.
Check your settings in the Audio Midi app which is located in the Utilities folder.

Repairing the mysteriously muted Mac
The background on the issue is that there’s a small sensor switch inside the headphone port. When you insert a headphone jack, the sensor understands what's what and changes the sound output setting to Headphones. If you insert a jack for digital audio output, the device changes to Digital Out. When you remove the jack completely, it should read Internal Speakers.
The spirits tell me that there’s a very good chance that you recently had something jacked into this port—a set of headphones or a cable leading to powered speakers, for example. When you removed the jack, something in the port prevented the sensor from tripping correctly. That’s why you see Digital Out instead of internal Speakers.
The solution is to force the sensor to do its job. The safest way to do that is to simply run a jack in and out of the port a few times. Much of the time, this takes care of the problem by correctly tripping the sensor. If that doesn’t work, there may be gunk in the port. Before turning to more invasive techniques, get a can of compressed air, attach the small tube that fits the nozzle, and blast a few shots of air into the port. With any luck, that should dislodge the gunk and the port will operate as it should.
If that doesn’t work, find a foam-tipped swab that fits (electronics shops generally carry them), dip it in rubbing alcohol, and gently insert it into the headphone port in an attempt to wipe away any stubborn gunk. I recommend foam rather than cotton swabs because the cotton variety might leave threads behind. (This same technique works well with misbehaving headphone ports on devices such as iOS devices.)
It's possible that gunk has nothing to do with it. Rather, it may be that the switch just needs a subtle nudge. If a jack or swab doesn't work, I've heard of people successfully resetting it with a deft poke of a toothpick.

Morese Code sound coming through my external speakers

Recently I've been getting Morse Code sounds coming through my external speakers. It's not all the time but at least 2-3 time a day. Any idea?

If I have my cel phone near my iMac, every now and then I get a sound that could be described as Morse code like. It has no lasting effects, so I don't worry much about it.

HP 4330s SRS Premium Sound not working with External Speakers

And this is my second topic and rant!
The SRS Premium sound driver doesn't work with USB Speakers.
It doesn't work with Bluetooth speakers either!
In other words it only works with the Laptop speakers.
ARE YOU KIDDING ME!
SRS Premium sound for Deeper Bass and Clear sound enhancement bla bla bla now in you HP Laptop
but ONLY with your LAPTOP SPEAKERS!
ARE YOU KIDDING ME!
DEEP BASS on these cell phone speakers!!! Really???
Why doesn't the SRS Premium Sound driver work with external speakers!
I believe I have used SRS Sandbox before and ALL THE SOUND was directed to that driver and it worked with everything!
WHY DOESN'T YOUR HP DRIVER WORK WITH EXTERNAL SPEAKERS!
Is everyone in HP a bloody RETARD?
FIX YOUR DRIVERS!
End of rant!

Oh BTW {Content Removed: rant} http://www.srslabs.com/landing.aspx?id=693#23
23. Will the SRS Audio Sandbox work with my USB speakers or Bluetooth speakers?
Yes, the current version, 1.6.6.0 will work. If you have a previous version that is not working with these speakers, please upgrade to this version.
Do you have anything else to share with me {Content Removed: rant}

How does one reestablish no sound from either internal or external speakers in iMac 10.6.8?

MacBook Pro internal and external speakers not responding

For the last 3-4 weeks, I've had odd bouts of incidents where the speakers (internal) stop responding at all. I have a set of external speakers that are normally plugged into the computer, but they have also stopped producing sound. Is there any way to troubleshoot this to determine the source of the problem. (PS: NOTHING works. Even Skype contacts, iTunes playback, notification sounds -- everything is out.)

Bad really, coz if you could see a red light it would be much easier to solve. The red light would indicate it was operating as a toslink (digital audio) connector and the switch that changes it from analog to digital audio was stuck. It can be unstuck by wiggling a toothpick or cocktail stick in the socket. It means it's much harder to diagnose what your problem is.
Suggest as a first stage that you attempt a PRAM reset followed by a SMC reset if still not working, then report back here.

I can't hear iTunes music or internet radio but internal and external speakers are definitely working. Is there a key stroke I have set or some other, maybe Yosemite, issue?

I have checked my internal speakers on an iMac and also the external speakers - all working. When play music in iTunes the sound bar moves but no sound is heard. Same problem if I want to listen to the radio via internet. Has anyone a suggestion. Is it a Yosemite issue - I have had others involving printers. thanks

like davis says then even though I have connected headset and external speakers to my imac then at boot up the boot sound comes out of the imac speaker
but once booted into OS X all audio is played out of the headset and ext speakers and the imac speakers are silent as the grave

Sound panel cannot see external speakers

I have a couple year old imac upgraded to 10.5.8
I'm attempting to use external speakers via this path >> wireless to airport express >> optical to separate amp >> unpowered speakers. This used to work (maybe prior to upgrade to 10.5.8?), but now I
can get it to work ONLY using analog link from airport to amplifier, but not optical, and ONLY for iTunes. Itunes lets me select internal and externals speakers using the little icon on the lower right.
Video viewed via safari only allows internal speakers. If I go to preferences/sound/output it only shows the internal speakers as a selectable device. Could not find any way to add one so I assume if the system can't discover it you cannot add it.
I reinstalled Airport and tried to reset the PRAM (?). Neither hurt but didn't help either.
Any suggestions would be appreciated. I don't much care whether it's an analog or optical link to the amp, but I sure would like to hear internet sourced music via my external speakers.
thanks

I've tried each usb port and they still don't work.
So these are the older type that connect using USB, and not the "II" version that connects using the mini-stereo jack? I ask, because I thought USB version does not work with the latest Mac OS X. I guess it must work, based on what you wrote.
Since noticing this problem, have you shut down (powered off) the iMac and then started it back up? For hardware, shutting down is not the same as just restarting.
Some sound-related settings are stored in PRAM, so you can try resetting PRAM

No sound coming out of external speakers

Here's my situtation. I just recently received my MacBook and I wanted to connect my external speakers that I used with my previous PC laptop. It worked perfectly with the PC laptop. When I plug in the speaker cord into the port, no sound comes out of the external speakers. But sound comes out of the internal MacBook speakers.
I plugged it in the right port.
Volume is on both in the MacBook and the external speakers.
Speakers are on.
Speakers worked fine with my PC laptop.
What can i do? The connection is fine because it was just plugged in my PC laptop and they were working. Thanks in advance for any help.

Thanks for the reply. This is what i tried...its really weird but it works.
I plugged in the speaker plug into the port with the headphone symbol and now sound comes out of the speakers! (Maybe this was the correct port in the first place! Sorry for the newbie mistake.) I was used to ports being color coded and I just plugged in the green speaker cord into the green port on my PC.
So the port on the left is for audio in right?
And the port with the headphone symbol is for headphones and speaker (audio out)
When I go to to System Preferences, it recognizes the speakers as "Headphones". But I don't think that really matters.
Thanks for the help. I have sound now coming out of my external speakers.

Enabling internal when external speakers plugged in

is there a way to enable the internal speakers when i have external speakers plugged in on my 24" iMac??
i want this cause i use a Bose Cinemate® speaker system and it powers off after inactivity/no sound ... so then I don't hear alarms etc ...
btw i've asked Bose and they say there's no way to disable their power off timeout ;-()
TIA
Barry

Hello mate
I have a similar headache wanting to connect bluetooth speakers as well as plugged in speakers to play itunes in 2 rooms at the same time...nigh on impossible and is still a nightmare- however a solution that may work for you is this..http://www.versiontracker.com/dyn/moreinfo/macosx/18611 - its a piece of audio software called audio highjacker that allows you to play external and internal speakers at the same time. It wont work for me due to the latency or delay to my bluetooth - it plays the same tune a second or out of sync - so in one room they are just into the chorus while the other room they are still on the verse!!
Anyway download Audio highjacker and go to itunes (or whatever audio you want to highjack) open audio jack and click the application in its menu window. make sure source type is 'application' and mute is off - then click highjack - then 'click here to insert effect' choose 4fx and then auxillary device output - this will bring up a menu where you can choose what you want playing thru the other speakers or internal - this is from memory so apologies if its a little inaccurate - but this will play internal and external speaker at the same time - although not perfectly sychronised
hope this helps
cheers
Mike

Can u have internal AND external speakers on???

Can both the internal speakers and some of my external speakers be on at the same time??

Allan,
No, unfortunately you cannot. Having external speakers plugged into the optical/analog output port automatically mutes the internal speakers.

L440: Sound problems internal speakers

When I pause playback of an .mp3, there's permanent white noise coming from the internal speakers.
Stopping the playback stops the white noise after approximately 4 seconds. I never had this issue with any laptop / soundcard. Can this be fixed?
I have the latest BIOS and drivers installed. Headphones are fine (no white noise).
Maybe the inbuilt L440 soundcard has a problem. I had to return my first L440 because there was a loud plop when starting playback and the left speaker was way quieter than the right one.
In the German part of this forum people are reporting problems realted to the internal speaker (cracking sound, white noise).
Solved!
Go to Solution.

Blade,
It could be the speakers have a pinched wire causing a short, so the suggestion from the support specialist could be a good suggestion.
However, I believe we are aware of and have a fix for these symptoms via BIOS. Let's give that a try first.
We believe there was a problem that caused these symptoms in BIOS 1.53 through BIOS 1.58 on L440 and L540 systems.
Download and install the latest BIOS version 1.60 (J4ET60WW), or newer, from the Lenovo eSupport website:
BIOS Windows Update Utility version 1.60:
