TS1574 no audio from built-in speakers and red light visible through the headphone port

My 15" late 2006 MBP has just stopped producing sound from the internal speakers and for the first time there is a red light visible inside the headpbone output port. Apple support says contact support but since I'm a long time out of even my extended warranty I wondered if anyone had a fix-it suggestion I might try myself?

Try to plug the headphone into and out of the headphone socket couple of times
to flip the microswitch in the socket.
Red light visible means sound output is stuck in digital mode.

Procedure is same for 10.6

Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
If these steps do not help, repair Apple Store is needed.

TS1574 no audio from built-in speakers on MacBook

Anyone else have this problem? Using a 13" MacBook Late 2007.

Remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.

No audio from built-out speakers on my Mac book pro

no audio from built-out speakers on my Macbook pro, but with external headphones or speakers it does work. I see a red light inside the audio line-out port when you disconnect devices. What can I do?

The internal switch is stuck.
Insert the earphone jack several times.
Blow real hard into the audio output ort.
Take a toothpick and jiggle inside the audio output port.
If no success, visit the Apple store genius bar.
Ciao.

HP Pavillion dv5-1235dx laptop - No audio from built in speakers of recently purchased laptop

I purchased my laptop (HP Pavillion dv5-1235dx laptop) from best buy on Saturday, May 9th, less then a week ago. Yesterday the audio/sound stopped working completely - from the built-in speakers. I can hear ALL sound just fine from headphones. Only the internal speakers aren't funcioning. I did online troubleshooting, and also chatted with a technician, and I still have the same problem. I ran all updates, the status on the sound driver says it is funcioning properly. Even the little fluctuating green bars (on the volume control) SHOW that sound is coming out, but still unless I have headphones in, no sound comes out. The HP monitering software DID pop up and say there were critical errors and the computer needed to be updated yesterday, but I don't know if that was related because once I did all the updates, the audio still had the same problem. Please help me out.
Thanks,
Kalli

If it is less then a week, just return it to bestbuy. You may have a loose connection in speaker jack.
Have you try to use recovery DVD? try to install it to the factory setting.
If it does not work, definitely you have a hardware problem.

No audio from built in speakers

I have a HP G60-530US notebook... My problem is no audio from speakers. I do have sound from head set when pluged in..

Sounds like it might be something inserted that was broken off inside. Was probably done trying to free up the digital output inside the jack when no audio first appeared. Don't think it would be part of the jack that hasn't retracted, but if it were, you'd be facing a repair -- not sure how expensive, but could be expensive enough. If something broke off, can't think of an easy way to get it out. Maybe some double stick tape or adhesive on the round tip of something: insert, make contact and pull. But don't think you'd get enough traction. Might end up leaving the adhesive or tape inside, which wouldn't look great when you send it back. Probably just send it back.

No audio from built in speakers at random times..

Have you tried resetting the PRAM? The volume settings are stored there, so resetting the PRAM may help with volume problems.

My macbook pro volume is locked. there is a circle with a line through it when i press the volume buttons but no volume will sound. music and videos will not play and there is no red light on in the headphone jack.

Any suggestions of what could be wrong? or how it can be fixed. I have not updated it or anything. this just randomly happened about 2 hours ago. I tried looking for answers but nothing has worked so far.

I tried all of the fixes above and quite a few others like resetting the pram and nvram and what finally worked for me was resetting my sound card from Terminal. Open Terminal and enter the command sudo kill -9 `ps ax|grep 'coreaudio[a-z]' | awk '{print $1}'`. It will ask for your password, enter in your password and press enter. The sound card will be reset and your audio and volume control should be restored..

Desktop Computer dc5750 shuts down and red light flashes on front of computer and won't start at all

I have a DC5750 HP Compaq Computer it is 6 years old, but I have 4GB Ram, Nvidia GS8400 Graphics Card, two one TB Hard Drives. While I tried to re-installed my operating systems it all of a sudden shut down not once but twice, I opened up the side of the computer and found that it was hotter then normal. I let it sit for a while thinking it maybe over heating after hooking it back up I turned it on again nothing happened except a beeping noise and red lights flashing on the front. Can this be fixed as money is an issue.
Thanks
Rob

TS1574 no audio is working on imac and no audio device available to choose from

I am receiving no audio out of my IMac and no option to choosing the internal speakers device. Any thoughts would be appreciated. Originally thought is might have been a virus but down loaded software and no fix to solution.
Thanks,

Take each of the following steps that you haven't already tried.
1. Start with the steps recommended in this support article.
2. If your model has an audio-out (headphone) port, and a red light is coming from it, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
3. Boot in safe mode. You don't have to log in; just reboot as usual when the login screen appears.
4. Reset the NVRAM.
5. Reset the SMC.
6. Reinstall OS X after backing up all data.
7. Make a "Genius" appointment at an Apple Store.

No Audio from built in & external headphone from HP Pavilion dv6810us Notebook PC

I have HP Pavilion dv6810us Entertainment Notebook PC. You can find the complete product details @

When I play any video file only picture is visible but no sound is coming from built in speakers. Also audio is not coming although I connect headphone. The speaker icon in the system tray have 'X' (Red cross mark) on it & when I hover mouse on it is displaying message "No Audio Output Device is installed", so I cannot open the volume control.
I don't know how it happened suddenty. Everything was working perfectly fine before. I have not uninstalled any driver. My laptop comes with preconfigured Windows Vista Home Premium SP1 edition & Altec Lansing speakers. Also I can't see "Sound, video and game controllers" in the Device Manager. I tried to "Add legacy hardware" to add "Sound, video and game controllers" in Device Manager, but I couldnt find out the Altec in the manufacturers list.
HP customer care suggested me to install Conexant High-Definition Audio Driver from ftp://ftp.hp.com/pub/softpaq/sp40001-40500/sp40170.exe. But when I try to install it, I am getting error "Driver Installation failed : Could not find the device for this driver."
Can anybody suggest me how can I enable audio without loosing my data on it?

Go to Sound via Corntrol Panel. In Playback tab you should see Internal Speaker/Headphone with message showing the conexiant working and also a tick in green circle. If not select and apply or OK. This should solve your proble. If not then follow this:
Go to Device Manager via the Control Panel and look under Sound, Video and Game Controller. The active drive like High Definition Audio Driver should be listed. Right mouse click (dont do anything but select Properties and select Driver Tab and see if "Roll Back Driver" is high lighted, if yes then revert back to your previous driver. I think from here on you should be able to manouvers around and get your sound.

Simultaneous audio from outputs 1-2 and outputs 3-4?

Hi guys,
How do I get simultaneous audio from outputs 1-2 and outputs 3-4? I'm running Logicpro 7.1 through an M-Audio FW 410 hardware interface.
I'm trying to set things up so I can monitor through my mixing board to eleminate the weird echo sound you get in your headphones when recording.
I thought I could do it in logic by creating an ouput 1-2 and output 3-4 channel strip where ouput 3-4 will have the "i/o" plugin and in the plugin settings, Out would be set to 3-4 and input set to 1-2, this way sound will always come out of output 1-2 which will go to my speakers and output 3-4 to my mixing board. Please help!

I'm trying to set things up so I can monitor through my mixing board to eleminate the weird echo sound you get in your headphones when recording.
The 'weird echo sound' is because you are hearing Logic's software monitoring alongside direct monitoring of the inputs (either via the interface, or your mixer, depending where the headphones are plugged in.)
You can avoid this by setting the monitoring level on the record-enabled track to zero. (recording tracks have two level settings. Normal playback and record input monitoring. See page 282 in the Logic Pro reference manual.) It will not affect your record levels, or your input metering.

I cannot hear any songs or movies from my laptop speakers - the headphone port works and a red light is showing? The output sound settings are showing as digital optical only? Any ideas :)

I used the headphones in the laptop for the first time yesterday and have had this problem ever since. Any ideas

The internal switch in the audio output port is stuck. Try inserting the earphone plug a few times. If no success, try jiggling a tooth pick inside in order to trip the switch.. If still no success, have the technicians at the Apple store genius bar do it for you.
Ciao.

My sound is coming from my built in speakers instead of through the headphone jack.

I have an Envy 15 1270ca and last night it froze while I was listening to music, forcing me to manually shut it off by holding down the power button. When the computer came back on, my sound was coming out of my built-in speakers instead of my external speakers through the headphone jack. I checked the speakers through my mp3 player, so I know that they are working, so it seems to be the jack which is not working.
Any help is appreciated!
This question was solved.

Please Reinstall the sound Drivers and Make sure that the no ear phones are plugged in when we reinstall the sound drivers, this should work even after doing this if its not working then please set the BIOS to defaults this should work

Why would the audio play through the headphones but not the speakers?

I am working on an app that has embedded video. The audio works fine through my speakers and headphones as it does for some of my coworkers, but I also have other coworkers who get audio through the headphones but not the speakers. It's a variety of devices, 4, 4S, and 5. Any thoughts?

If you are working on developing an app perhaps you should try the developers forum.

I'm trying to reverb an audio clip in my timeline and I can't find the effect tab in the browser to drag to my audio clip to reverb. I can reverb the clip in the viewer but can't it won't drag to the timeline. I'm using FCE

I'm trying to reverb an audio clip in my timeline and I can't find the effect tab in the browser to drag to my audio clip to reverb. I can reverb the clip in the viewer but it won't drag to the timeline. I'm using FCE

You cannot drag the effects themselves to the timeline. You add them to a clip in the Viewer, just as you have done.
If the clip was already in the timeline when you opened it in the Viewer (by double-clicking it in the timeline to open it in the Viewer) and then added the reverb effect, there is nothing further to do, you have added the effect to the clip. You don't drag it back to the timeline.
You only have to drag the clip to the timeline if the clip was not already in the timeline (for example, if you opened the clip from the FCE Browser; or set different In and Out points in a master clip to use a different portion of the master clip in a different location in your timeline).
Depending on the effect you add, you may have to render the timeline after adding the effect. But I don't think reverb requires immediate rendering. One other note, you said you were working with an audio clip ... audio clips need to be AIFF (not MP3 or something else) and preferably 16-bit stereo.
