No audio on computer or external speakers

Hi,
Neither my computer nor external speakers have audio. While trying to determine what the problem might be, I think
that I inadvertently deleted the sound driver.   When I was troubleshooting in Control Panel under the sound
category  I selected the disable button not realizing that it would actually delete the driver software.
Is there a way to recover that or will I have to purchase new driver software for my computer? I s there any way to
get a free download on sound drivers or are there any reasonable ones out there that you know of? I don't have a
warranty on my computer.
Thanks for any advise or help.
This question was solved.

Hi,
You're welcome
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp48501-49000/sp48668.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall. If there is currently no IDT entry here, just proceed as below.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.
Let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.

No more audio output without the external speakers!

Hi,
I was watching some movie in FrontRow and i noticed that when i put away the external speakers there was no more sound cming out from the speakers, however when plugging back in the external speakers there it was the sound.
i ignored that and did the update of the entire system and the smc update (which by the way helps the air flow within the machine since it lowers the temp of about 10 °C and i can't hear for now the fans spinning).
And now when i wanted to look into it whithin the system preferences the volume bar is greyed out when not on the external speakers.
Any help would be immensly appreciated!

1. System Preference > Sound > Output > Internal Speakers
     Make sure that Mute box is not checked.
2. If there is red light visible in the headphone port plug the headphone
    into and out of the port 5 or 6 times to flip the microswitch inside.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.    http://support.apple.com/kb/HT3964
   Choose the method for:
   "Resetting SMC on portables with a battery you should not remove on your own".
5. Some have reported that reinstalling Lion helped them.
6. You can take it to the Apple store and have it fixed.
Best.

Audio not playing through external speakers

I have all the right connections and get nothing.
I am trying to use my laptop in my home theater room. I have a DVI to HDMI cable for video and then I have a Mini Plug adapter (headphone jack) on a Co-AX cable for my audio which is plugged into my receiver. I went into the menu of my receiver and made sure I selected the correct set up and I still get no audio. I am not getting any video either for that matter. I have a HD Projector with 3 HDMI inputs so I am not sure why I am not seeing anything.
Now I do have an HDTV elsewhere in my house and I hooked my Macbook Pro to that and switched the input of the TV to HDMI and I WAS able to see my desktop on the TV. However, the audio was not playing. I had the audio plugged into the PC Audio Input on the TV but only heard the audio when I switched from HDMI to PC on my TV.
I only hooked it up to my HDTV as a test to see if my cables were bad which they are not. I am just not sure why I can't get it to work in my Theater room!

Its not weird at all. FCP is designed for it's output to be monitored on an external TV and speakers via your Mac's Firewire output (or dedicated capture card, if you have one). If you prefer not to monitor the recommended way, in FCP, go to View->Audio Playback and choose the setting you want.

How do I connect Apple TV to external speakers and my TV?

I just bought an Apple TV for my studio apartment and have it connected to my TV via HDMI, and use AirPlay to stream my music and videos. Video works great, but the my TV's internal speakers are low quality. So, I would like to have my audio come from external speakers (which I have not bought yet), for the following 2 scenarios:
Listening to music via AirPlay, preferably without having to turn my TV on.
Watching videos on my TV, with the audio coming through my external speakers rather than the TV speakers
I see my Apple TV has an Optical Audio (Toslink) port, but the salesperson at the nearby electronics store said none of their speakers have Toslink cables, only 3.5 mm (or USB). The only solution I found is an AV receiver box that has optical input but costs hundreds of dollars. I am looking for something cheaper and am willing to settle for "pretty good" sound quality.
Is there another way to get this to work?
This article recommends using a digital audio converter (DAC) to connect the Apple TV to a stereo amplifier. This seems like it would satisfy scenarios (1) and (2) above.
Also, I found this "Toslink to 3.5 mm adapter" for a few bucks; could I just plug that into my Apple TV and then connect it to any speakers (like computer speakers) with 3.5mm input?
Any ideas would be appreciated.

Rex,
Since the toslink is optical, the 3.5mm adapter will not work for you as it is only ment as a conversion to a mini-toslink cable. Your first option of using the DAC, is in my opinion the best and perhaps only way to get audio out without going to a fancy amp or tuner first.
One option that I'm considering is the Bose Solo TV sound system. It might set you back about 4-Grant's, but I generally enjoy the sound of bose for most music/tv/movie purposes; and it has a direct optical audio input that you can run either from your tv or your ATV. Whatever audio you're sending to your TV via the HDMI, should go to these speakers through your HDTV's toslink output with equal digital clarity.
I've read a few other posts on the apple discussion forum which lead me to believe that the optical output of the ATV might not work so well after the 5.2 update... so whatever I do, it won't be JUST for use with the ATV.

External speakers no longer work with airport ---- what gives please help

Itunes 8.2 no longer shows the drop down menu where I can choose 'computer' or 'external speakers'. I've used this feature for years, and now, it's gone. Where'd it go?
There is a green light on the Airport. The 'Look for remote speakers connect with AirTunes' is checked. The Imac is reading the wireless network. The external speakers are connected correctly.
Where the heck did it go....and more importantly, how do I get it back?

32DT1U HDTV: HDMI to Laptop, Sound to External Speakers?

Hello,
I have a 32DT1U Toshiba HDTV and I am trying to connect my laptop to the TV via an HDMI cable but I want the sound to go to external speakers. Is there any way of doing this? When I have the HDMI cable connected from the laptop to the TV and a Y-cable (red/white audio rca) connected from the laptop audio jack to the external speakers the audio still comes from the TV. Any help is appreciated.
Thanks.

Nevermind I found out how to do it. All I had to do was right click the volume icon in the taskbar, select Playback Devices, then set the headphone or line out to Default.

TV off audio output possible to external sound system?

One thing i like about ATV2 is the ability to ;isten to my itunes music.
I havnt bought one yet but wanted to know if it is possible and if so how to have the TV turned off and audio outputed to my external speakers? My current speakers are not SPDIF just anolog inputs
It would seem crazy to have to run the TV screen while I was just listening to music. My TV has HDMI inputs and looks like an optical in as well.
Any comments on best way to set this sort of thing up or do I have to have the TV on?

Yes.. If you have a separate av receiver powering your speakers (even if it passes the video signal through). if you just plug external speakers into the TV you turn them off when you turn off the TV.

Apple DVD Player not recognizing external speakers

I have connected a pair of Logitech V20 notebook speakers to my MacBook Pro. I adjusted the System Preference settings/Sound/Sound Effects - play sound effects through "Logitech USB Speaker" and that works fine. I can hear my laptop's beeps through the external speakers.
But when I put in a movie DVD and the Apple DVD Player boots up, the sound does not come through the external speakers. So, in the DVD Player, I selected Preferences/Disc Setup/Audio/Audio Output and the external speakers are not there - only "System Sound Output" with nothing else available/recognized.
So, how do I get the DVD Player to put the sound out through my external speakers and not the laptop internal speakers?

"System Sound Output" at DVDPlayer's preferences is just fine - it refers to the output that has been selected at System Preferences - Sound
No sound from USB speakers when booting is o.k., too: At this point those drivers that are needed haven't loaded yet.

When external speakers are plugged in to headphone jack, sound randomly goes back to internal speakers or digital audio setting, then back again

I have an essentially new MacBook Pro with Lion and all updates applied, and am wondering if this is a hardware or software problem. Essentially with something plugged into the headphone jack, things work as they are supposed to for a while, then the sound will switch back to internal speakers, or sometimes 'digital out' (I can watch it change in the system settings), and then often switch back. It doesn't seem to follow any sort of pattern or be related to any specific application that could be open, and happens with different sources of audio (iTunes, streaming from the web), and different external speakers or headphones plugged in.

Sounds hardware related. If it's brand new, and you're still under warranty I would have it checked out.
I have not experienced this on my computer.
As I understand it, you have analog RCA outputs from an 1/8" to left and right RCA outputs. when you're randomly using the computer, it'll switch to internal speakers, then to digital audio, back to your stereo analog external speakers.
This should not be happening and if it's happening with streaming content (I am unaware of anything that streams in 5.1 digital audio) then this must be something that an apple specialist should look at and consider.
Does this happen with the headphone jack out? when you hold your finger over the headphone jack area does a red beam come out of it *blinking* or just on? This will be a good indicator that your audio hardware is faulty. are you running HDMI out?

Lion audio dropouts with external speakers?

Since I installed OS 10.7.3 (upgraded from 10.6.8), I get audio dropouts whenever I use external speakers. I use my Mini (purchased a year ago in Feb 2011) connected to my TV for Skype, Netflix, and listening to iTunes, so this effectively eliminates my ability to use it. I don't get dropouts if I use the internal speakers, and it doesn't seem to matter whether I'm using iTunes to play something resident on the internal hard drive or watching something on Netflix streaming over wifi, or whether I have wifi or bluetooth on or off. The external speakers are run through an HDMI cable connecting the computer and the TV.

Updates applied, at least one of which caused reccurrence of my audio dropout problem (I'm guessing iTunes is the culprit):
iPhoto Update 9.2.2
GarageBand Update 6.0.5
Digital Camera Raw Compatibility Update 3.10
Application Loader 2.5.1
Safari 5.1.4
iTunes 10.6

Audio not coming out both external speakers on Lenovo Horizon All-in-one

I have just received my Lenovo Horizon 27 inch all-in-one pc and I've noticed a problem with the audio. When I plug in my external speakers I only get audio out of the left channel. I noticed another person with the same problem posted to the forums some time back but the Lenovo tech never got back to him with a solution so I'm really hoping I'll have better luck.
The sound comes out propperly when headphones are plugged in but my speakers only output a single chanel of audio. The speakers work fine on other PCs. As was suggested in the other thread, I compared the headphone jack and the speaker jack and they are identical. Same number of stripes, same length, and I believe the same girth.
Here's the url for the other post I mentioned: http://forums.lenovo.com/t5/IdeaCentre-Desktops-Home-Servers/Horizon-27-sound-issue/m-p/1475392/high...
I also can't seem to find where the number is to call for support so if someone could help me with that I'd be very appreciative.
Thanks,
Charles

Okay, so I called Lenovo support and as always, they were polite but their solution was that it was a software issue and I needed to restore my computer, so not very good advice but often given by every tech support. It's like cutting off your hand because you have a cuiticle.
Anyway, so in all the sitting and waiting I had a thought come back about when I used to manage a computer store that sold Macs. Apple, when they released the Macbook Air, tried to squeeze so much into the tiny case that there were a million problems with the device one of which was that some headphones and speakers worked fine (namely ones made by Apple, go figure) and others wouldn't work at all. It was a design flaw related to have very low tollerances for minor differences in the headphone jacks length et al.
So I used an extension audio cable with my speakers and it works fine now. So the answer is that there is a design flaw in the Lenovo Horizion related to the effort to squeeze so much into the thin device which lowers the devices tollerance for variations in the size and shape of the headphone plug. I hope this helps someone else since the solution is simple and if it had been in a database it would have saved a lot of time for me and the techs. Not complaining, just wanting to put this information out there for others who might be experiencing the same sort of problems.

Why has my MacBook Pro stopped outputting audio on external speakers?

Since buying a MacBook Pro in April 2007, I had no problem playing recorded music and Internet radio on external analog speaker systems in two different houses. Suddenly this summer, the audio no longer plays through the external speakers --though it still works fine with the internal speakers. There were no major changes or accidents. The only technical issue I had was the recent malfunctioning of my laptop battery, which Apple acknowledged was defective and replaced yesterday. (I hoped that the problem might be resolved by the new battery. But it hasn't been.) Most of the discussions I've read about audio troubles with the MacBook Pro don't apply to this situation. (The most-discussed problem had to do with the internal speakers no longer working, often because the MBP's audio out port had inadvertently gone into digital audio mode.) My MacBook Pro is a 2.33 MHz Intel Core 2 Duo, OS 10.4.11, The mute button is not on. The speaker sound is up to max. And when I check the Sound status in System Preferences, the info line correctly identifies the speakers. The default ID readout is internal speakers. And the ID reads external speakers when I plug the external speakers into the headset/audio out port, But the sound plays only on the internal speakers, not on the external speakers. I miss listening to my music library and favorite NPR stations on a good sound system, where ever I go. I'd be grateful for any help. Thanks

If your computer was hot it wasn't asleep - it either didn't go to sleep or it work up after you put it to sleep. I've seen both things happen. First, read this article and follow the instructions.
1) For the next few days/weeks pay attention to the blinking light on the front of your computer when you close the lid. Don't put the computer into your backpack/case until it begins to blink. Wait a minute or so after it starts to blink to make sure it doesn't stop blinking - the signal it woke back up.
2) having followed the above instructions, if you take the computer out and it is hot again or if you take it out and discover it has powered down (you'll know this because when it starts up the battery will be drained and you'll see a progress bar over a ghostly display that will eventually become normal) immediately start the Console program and perform a search on 'sleep' and then 'wake'. This should bring up all the recent log files about sleep state changes (going to sleep and waking up). You should see one for when you put the computer to sleep and put it away and the next one should be just after you got it out. You'll find at least one though that shouldn't be there. That will tell you when the computer work up (when it shouldn't have) and might give a clue as to why.
One of the whys could be a magnet that is making the computer think the lid has been opened.

Streaming Audio to external speakers

So here's what I want to do.
Use Frontrow to watch movies and have the auido streamed via Airtunes to external speakers.
I've tried importing movies into iTunes but it only plays the audio through the computer. I'm guessing there is no way to seperate the video and audio which is why audio is through the computer?

Okay, so the next question is, can you play videos directly in iTunes and have the audio go through the AirTunes? Even if they live inside iTunes, Front Row plays videos through QuickTime and not directly through iTunes. Since QuickTime can't play audio through AirTunes, that might be the problem... You might need a utility like Rogue Amoeba's Airfoil:

Right click your volume icon in the notification area and select "volume control options". From there, you should be able to select the external speakers.
I hope that helps!
