No audio hardware installed

All of a sudden my sound disappeared. When I run the troubleshooter it states that a hardware change has been detected. But no hardware sound device is now installed. I cannot use my sound jacks or the internal speakers. I've heard that HP isn't helping with this problem.

Hi @gf1930
Welcome to the HP Forums!
It is a terrific place to find answers and suggestions!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I grasp that you changed the audio card and now you do not have sound.
Did you try going into Device Manager and scanning for hardware changes?
If you should require further assistance please provide your exact model of HP notebook and your Operating System. If you did replace the sound card which one did you install?
How Do I Find My Model Number or Product Number?
Good luck and

Is there any ways to stop Quicktime player from occupying audio hardware?

Hi, my PC system is Window XP Pro SP2, HP xw8400 Workstation w/ 2G Ram. And the PC has a Digidesign Pro Tools HD 1 audio system installed.
My problem is that after Quicktime player lauches, it will occupy the Pro Tools HD's hardware. And if I want to start Pro Tools software, "digidesign hardware is in use by another application." warning will occur and Pro Tools software will then quit. BTW, Digidesign's audio driver is not multi-clients compatible.
I have set Quicktime player's audio playback device to PC motherboard's audio device, and system's audio device is also motherboard's audio device, I even have checked the "use default device only" option. I can't understand why Quicktime player still occupies Digidesign's hardware, even it plays back audio through motherboard's audio device.
Though I can quite Quicktime player before lauching Pro Tools software, I still feel it's annoying and inconvenient, and want to know some ways to solve this problem.
Anyone can help? Thanks in advance. I have asked for help in Digidesign's offcial forum, no response.
BTW, the Quicktime player version on my system is 7.6.5, and each time Quicktime player launches, the sample rate led on the Digidesign's audio interface will flash, indicating that QT player is accessing Digidesign's hardware.

I have a Blue Ant Q2 Bluetooth headset. When it's paired, is there any way to stop all audio from streaming to it? I want to hear the iPad "ring" so I don't have to have the earpiece in my ear all day, or be able to play audio through the speakers instead of the earpiece. I feel like I'm missing something simple.
You are missing something simple but lets get it to stop as you want. Go to Settings/General/Bluetooth turn it off.

Audio hardware missing after depot repair?

Damnedest thing. Just got my ThinkPad x200s back from Memphis where the main board was swapped out because of a really bad BSOD problem.
Discovered there is no audio, and so I thought I would just uninstall the audio devices via Device Manager, then let the system re-install. As there doesn't seem to be any audio hardware, it is useless to download drivers.
Anyone had this happen before?

Ok... well that, along with no startup sounds, coupled with no audio device (known or unknown) showing in Device Manager, sure seems to point at hardware.
Since you just got the machine back from a system board replacement at the depot, it makes sense to consider contacting them and having things checked again. Alternatively, if you're comfortable pulling the keyboard and a few other parts, you might take a peek to see if any connectors are loose.
Your hardware manual: http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/x200_x200s_x200si_x201_x201i_x201s_hmm_en... will give you an idea of what might be involved in that

How to set audio hardware input channels for narration & to what?

Searched forum - hope I didn't miss solution for the following:
Using PE3 in Windows XPSP3
Tried for the first time to add narration to a project. Was using a stereo/microphone headset. Got nothing but noise. Could record in Windows recorder and Audacity. However, the microphone as part of the set would not work in Windows Audio Hardware Test Wizard. The set was using a sound chip on the motherboard.
A friend of mine has the same OS, motherboard and is using PE3. He too had never tried adding narration - but tried with a USP connected set, and was successful.
I removed my stereo set, and connected a USB set. To make sure all settings were reset, I did a cold reboot. The USB set worked in Windows Audio Test Wizard. I opened my project again, and in Edit/Preferences/Audio Hardware, clicked AIIO Settings. Unchecked the old set (Realtek) in both the Output and Input Ports area, checked the USB Audio Device, moved to the top of both lists.
Then tried to add narration and got the error message "Your current audio hardware selection does not have any input channels. Please use Preferences>Audio Hardware to correct this problem.
Thinking that maybe this was a preset for the project and couldn't be changed, I started a new project, no video, just tried to add narration, and got the same message.
The entries in the columns in the ASIO Direct Sound for Full Duplex Setup menu for the USB Audio Device in the Input section are: 2048, 0, 1, 16, Yes
The only one of these that seems to be able to be adjusted is the second number - the Offset (Samples). The Audio Channels number is set to 1 and doesn't seem to be changeable. Suggestions?

When working with Audio in most NLE's, i.e. Premiere Elements, or Pro, there are basically three areas that can affect how the Audio is handled on one's system. First, there is the Sound settings in Windows (from Control Panel). Next, the Audio card/chip probably/possibly has a console to make settings at the card/chip level. Last, and these are really two locations, but I'm only counting them as one since they are both in the NLE - Edit>Preferences>Audio & Audio Hardware. This is where Steve is referring to. Check all settings, and I'd suggest doing so in the order that I listed them above: OS, Audio card, then Premiere. A Mute, or by-pass in the first two, can override the settings in Premiere, and you may have its setting correct, but still not be able to effectively use your hardware.
The exact settings chosen will depend on the exact hardware that is properly installed. Without knowing all of your hardware and other settings elsewhere, one cannot give you a definitive answer. Ideally, in the settings drop-downs, you *should* see your hardware listed. Look closely, as these can be a bit cryptic.
If you are still unable to get your hardware working properly, a fourth place to look would be Control Panel>System>Hardware>Device Manager for your Audio hardware. Check that Device Manager sees your hardware, and that it is working properly.
If all is set up properly, but still not working, report back with exact specs on your system, including all of your Audio hardware. There are possibly some more steps that can be taken. I will not mention them now, as they *should not* be needed. If you do need further assistance, please list every option in all of the drop-down lists from Premiere, so we can know what your choices are.
Good luck,
Hunt

7640 Media Center No audio after installing ATI HD 4670

I tried a video card upgrade, I was running ATI 1950, purchased an ATI HD4670 so I could make use of HDMI input on my new monitor and improve performance.
I uninstalled the existing drivers and followed the install info for the 4670. The card appeared to configure correctly and video function was great BUT i had no sound from either front or back outputs. In audio hardware set up I could no longer see Realtek HD only the ATI HD Audio as a choice. I did install teh full Catlyst Control Center version 9.1.1.
Any help greatly appreciated :-)

Install the latest ATI drivers, the Microsoft drivers should load by themselves. Install Realtek ATI HDMI drivers (Google "ATI HDMI Audio Device" ).
Install "ac3filter" (get it from a google search). Restart your PC after that. In ac3filter Main Tab check "Use SPDIF" and choose 5.1 audio out. In the SPDIF Tab choose the formats your Surround Sound can decode (DTS, AC3, PCM 24bit) .
Turn on your receiver. In the Audio control panel choose Realtek HDMI Output as Default, choose Properties, click Supported Formats Tab and verify which formats will play (disable "Microsoft WMA Pro Audio" ) and do the same in Advanced (choose 24bit). Now 5.1 surround should work.

Thank you

See my reply in the other thread. Please don't double post as it is confusing to give answers. Unfortunately your picture doesn't show any helpful information to give us a clue as to what the problem is. A more helpful image would be of the same view but with the Input/output selection shown (rather than the fx view) by clicking on the double arrow icon to the left of the fx one which is selected at present.

Adobe Audition 3.0 "Audio Hardware Settings" for USB Audio Interface HELP!

Hi guys.
I’m after some help in the internal settings of Adobe Audition 3.0 whilst I’m trying to run my condenser mic through my ART USB Dual Pre.
I have the USB Dual Pre all set up in my Windows 7 set up (it automatically becomes the default recording device when it’s plugged in), phantom power enabled, XLR cable plugged into the right socket of the two available (is there any difference? I’m just recording voice tracking for radio announcements), headphones plugged into the monitoring jack at the back. Levels are turned up enough that they will pick up the noise, if there was any.
I go to the “edit” tab in Adobe Audition 3.0, hit record and nothing comes up. I’m not getting any sound at all registered on the computer. I’ve downloaded and installed Asio4All, but can’t for the life of me figure out the configuration within the “Edit > Audio Hardware Setup” to make the damn thing pick up my voice. There’s mention of Audio Drivers (Asio4All or Audition 3.0 Windows Sound), USB Audio Codecs, Input/Output… it’s enough to make a man who’s not very good at this sort of thing cry (ie. Me).
Could anybody help a body out, please? I think I’ve done everything right except the configuration within Audition itself. A helping hand would be GREATLY appreciated.
Thanks so much!

Hey there,
Thanks for your reply! I'm not too good at describing what I'm doing, so I've taken screenshots of all the options in "Edit > Audio Hardware Settings" under Edit View and Multitrack view. They include both Audio Drivers available (which were Asio4All and Audition 3.0 Windows Sound) and the associated Default Input/Output options, as well as the Audio Driver control panels and the options that were checked/unchecked on them.
If anybody could tell me how to configure this so I can actually record from my USB Dual Pre, that would be one better than I can do!
Thanks heaps.

No audio devices installed Envy dv6

I recently installed Windows 8.1, and now no sound comes out of my speakers. I tried updating and reinstalling the audio driver but it still says that there are no audio devices installed. I've tried following the directions on a few forums and none have seemed to work.

You can try few more steps..
i) Completely uninstall IDT first from control panel and then download it from here
Temporily disable the anti-virus while re-installing the IDT.
ii) Run HP Support Assitant and check if any HP updates are pending..like BIOS Update..
Recently i came across a similar issue where the sound disappered after a adobe flash update also. So you an try uninstall/reinstall flash and check also.
Let me know what happens..
Also if nothing works then the last step would be to perform a recovery (factory reset). If problem continues after recovery also the it has to be a hardware issue..
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem

No audio devices installed? (Pavilion g7-1318dx Notebook Windows 7)

Someone please help me out with this, I would be so so soooo grateful.
From out of the blue my Pavilion g7-1318dx Notebook running Windows 7 won't play any audio at all. It says that there are no audio devices installed. I've been reading other posts on this forum for a couple days now, and none of the options have worked for me. Prior to the audio disappearing I haven't updated anything or installed anything new (though yesterday, I did install a few updates hoping that maybe the problem was that something was outdated... but it wasn't). I did a system restore, and still nothing. Also, I can't record sound either (obviously) as it's telling me there are no audio devices installed.
I ran the device manager, and under sounds, video, and game controllers the only audio device listed is AMD High Definition Audio Device (which is what my notebook uses for audio apparently, when I connect to my TV which, incidentally, works fine!) but the IDT HD Audio Driver is not working at all. I've tried reinstalling the driver, but I get an error every time and it says it's unable to install it. The answer might be a simple one to someone out there, but it eludes me.
So....anyone out there who can help me? Please.

Audio hardware detected is not supported

On one of our Win7 64bit 8440p laptops, the audio drivers seem to be installed, but Windows says "No audio hardware is detected". So, I downloaded both of the available IDT HD audio drivers (sp50589 and sp46721), but when I try to install either it says "Audio hardware detected is not supported". However, after it fails, Windows asks if it installed correctly, and if I want to try installing it with "Recommended settings". I tried that once, and the installation goes through successfully, but the audio still is not working.
When I go into Device Manager, the objects say "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)" when you go into the properties. To verify it's the drivers and not the hardware, I then rebooted, hit F8, selected the option to ignore driver signing, and lo and behold, the audio works. But I can't ask the employee to hit F8 and select that option each time.
Anyone have any ideas?

Wi-Fi: No Hardware Installed on MacBook Pro 8,2 (15 inch, Late 2011)

Hi Everyone,
For the second time now, I have to bring my Macbook Pro 8,2 (macbookpro8,2, 15 inch, late 2011) running Mountain Lion back to the Genius Bar due to a unrecognized Wi-Fi Airport adapter. The computer was purchased in March of 2012.
The problem started as I was watching 'The Daily Show" online, when suddenly, I lost connection. I clicked on the wi-fi adapter icon on the top menu bar, and saw that no access points were available when there normally were over 20, including mine in the house. I went into the network settings under system preferences and saw that the wi-fi card was off (although it was just on and still showed the full-signal indicator in the menu bar), and attempted to click the button to turn it back on with no response. All other options were either greyed-out or displayed no information. The Hardware tab didn't even display and the mac address suddenly became all zeros.
I rebooted the computer, only to discover the wi-fi indicator on the menu bar displaying no signal. Upon clicking on the icon, the dreaded "Wi-Fi: No Hardware Installed" was displayed. I tried resetting the SMC and PRAM/NVRAM with no success. I also rand the Hardware Troubleshooter ( Option - D upon bootup ) which neither saw the communications device nor reported finding any problem.
I brought it to the Genius Bar, and they ended up replacing BOTH the Logic Board, Wi-Fi adapter, and connection cable between the wi-fi adapter and logic board on July 23, 2012.
Now, it's October 10, 2012, and last night, as I was working through a VPN tunnel on the terminal on one of our remote servers, the SAME THING happened AGAIN! The connection was dropped, same scenario as above, and upon bootup I was greeted with the "Wi-Fi: No Hardware Installed" message again.
The hardware magically disappeard with no mention of this in the Console, as far as I can tell. The Console mentions the loss of connection and inability to contact DNS, but nothing relating to hardware.
For the record, the bluetooth continued to function both times I've had this issue. The first time this happened, I was running Lion and now I'm running Mountain Lion.
So apparently there is something really wrong with either the physical enclosure causing a short somehow, the quality of the Broadcom chip on this wi-fi device, or there's some type of software/power causing the chip to short out.
My compouter is as protected as can be - it's in a Speck plastic housing with a keyboard cover, which was purchased after the first incident, I use it on a hard flat plastic laptop tablet at home, and carry it around in a Timbuk2 Laptop bag. It also has never been dropped.
What's the problem here? Has anyone else had this problem?
Thanks and all the best of luck and success solving your own computer problems

Sorry for the late reply. I had a bad experience with the Apple Store and the 'Genius' Bar where I live. However, in the end, I received my MacBook Pro back from repair and everything is working.
Like I said in my previous post, the first time the Wi-Fi broke, I was using Lion. The mother (Logic) board was replaced as well as the Wi-Fi card.
The second time it broke, I was using Mountain Lion. Booting up the Recovery partition and Snow Leopard (new install) did not solve the issue. The Apple Store confirmed that the Wi-Fi card was broken through various testing, which I observed.
Since the attenna wires for the Wi-Fi run through the display, we decided the next logical step was to replace the Wi-Fi card and the display. The reasoning is that there could have been a short or cross connection in the attenna wiring that was causing the Wi-Fi cards to short-out/burn-out. The Bluetooth continued to work in both cases the Wi-Fi failed, meaning that it was unlikely a cable problem.
Since the display and wi-fi have been replaced (20121025), I've had no problems. The wi-fi card is working.
I'm glad the kext file solution has worked for you. I've seen posts on this solution; however, after determining that this was indeed a hardware failure (by using Recovery console, booting from Snow Leopard, and using Hardware Troubleshooter (it didn't even see the Wi-Fi) ), I didn't bother with fiddling with the kext (driver) files. Besides, this hardware is supposed to be designed to work with the OS without any problems whatsoever. Shame on Apple if they don't ship proper drivers for their hardware!

Is there a way to save multiple audio hardware settings?

Hi Everyone,
                       I use a multiple preamp set up to record. I would like to be able to playback and do my editing without having to have my preamps all plugged in and just use the computer's built in hardware. Of course as soon as I disconnect them Audition tells me I need to go back and set up my audio hardware settings since they have now changed.
Is there any way I can save the audio hardware settings so that I can switch back and forth between the computer's audio hardware and my preamp set up without having to go back and manually enter all the settings each time?

One feature request I've been meaning to submit has been remembering the previous settings for a device and defaulting to them when the device is re-selected. Thanks for the reminder on that.
As for CS6, you might be able to take advantage of the Machine-Specific Preferences feature to make this a bit easier. Here's what I would recommend:
Configure Audition with your primary audio device, get the Channel Assignments and all other settings how you like them, then close Audition.
Next, you're going to copy one of the Audition preference files to another location on your system. Your existing preference files will be located in one of the following locations:
       Mac OS X: /Users/<username>/Library/Preferences/Adobe/Audition/5.0/
       Windows XP: /Documents and Settings/<username>/Application Data/Adobe/Audition/5.0/
       Windows 7: /Users/<username>/AppData/Roaming/Adobe/Audition/5.0/
    (Note that the "Library," "Application Data," and "AppData" folders may be hidden by the OS by default.)
Copy the file MachineSpecificSettings.xml to the appropriate directory below:
     Mac OS X: /Library/Preferences/Adobe/Audition/5.0/
       Windows 7/XP (32-bit): /Program Files/Common Files/Adobe/Audition/5.0/
       Windows 7/XP (64-bit): /Program Files (x86)/Common Files/Adobe/Audition/5.0/
Launch Audition and make sure Preferences > Audio Hardware > Use Machine-specific device defaults is selected. Now, each time you launch Audition it should attempt to load your primary device and configuration. If it can't be found, you'll still be notified and able to select your built-in input/output, but the next time you launch with the primary device connected, it should load as if it never left.
There's a bit more information on Machine Specific Settings on our Inside Sound blog post. It wasn't intended for this use, but I think it will make this particular request a bit simpler. Meanwhile, I'll make sure we have a feature in the database to look into this.

HDD errors - Wi-Fi: no hardware installed - Flashing ?-Folder

Hi there,
for the last one year I'm having periodical issues with my macbook pro 13'' mid 2011.
Some time ago I started a discussion https://discussions.apple.com/message/22086569#22086569 concerning allocation errors on the file system etc.
I though I got it fixed with a new hdd sata connection cable. As it turns out I seam to only scratch the surface of a much bigger problem. As you can read in the title after getting allocation errors after a reboot my wi-fi hardware is not found (this also got repaired some time ago) and now i cannot boot into my system as I'm getting the flashing folder with the question mark in it.
With me changing cables and so I only get like 1 or 2 month of peace then the whole problem starts again. Could this be like a faulty logic board or some loose connection on it? I already paid like around 300€ for repairments on this **** thing and all they said or did was changing cables. I don't believe that cables are the source of the problem.
Do you have any other advices?
Thanks in advance

Hello Guys,
I am having the same problem. In the "No hardware installed" (Macbook pro - mid 2009 model os x 10.6) Help ...please....!!!

OSX Yosemite Wi-Fi: no hardware installed

Hi ASC:
I installed Yosemite about 2 weeks ago, and at first my wi-fi (at home & work) was working fine, but then about a week ago the Wi-Fi icon at the top of the toolbar got an "X" in the middle of it and when I click on the Wi-Fi icon it says, "No hardware installed". I tried resetting the SMC on portables with a battery you should not remove on your own (from another thread) but no luck. I've googled this, YouTube-ed it, but still no Wi-Fi back. Someone PLEASE help
I'm using:
OSX Yosemite
10.10.1
MacBook Pro (15-inch, early 2011)
Thank you.

In some cases, this issue is caused by a hardware fault. A loose connection, a short circuit, or a microscopic break in a solder joint may open and close depending on temperature, making the failure intermittent.
Test after taking each of the following steps that you haven't already taken. Back up all data before making any changes.
1. If you can connect to the Internet via Ethernet, Bluetooth, or a USB network device, make sure all available OS X updates are installed. If Wi-Fi is your only means of network access, skip this step.
2.. There are a few reports that the problem was solved by unchecking the box marked
Wake for Wi-Fi network access
in the Power Adapter tab of the Energy Saver preference pane. I can't confirm.
3. Reset the NVRAM.
4. Reset the System Management Controller.
5. Start up in Recovery mode. In the menu bar of the OS X Utilities screen, there's a Wi-Fi menu. Try to connect. If it works, select Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Message 'Wi-Fi: No hardware installed

MacBook late 2008 2 GHz Intel Core 2 Duo   OSX 10.9.2
Hi,
Some advice please re. the above situation.
I was working on my MacBook when the screen froze. I can’t remember the last time this happened. Pressing and releasing the power button to shut down did not work, so I pressed it continuously until MB did shut down.
After starting it again, I was surprised to see the Wi-Fi symbol at the top of the screen was not showing its bars as usual; in their place was a white cross. When pressed, the message ‘Wi-Fi: No hardware installed’ was revealed.
When I go to About this Mac : System Report : Wi-Fi, I see this:-
Software Versions:
CoreWLAN:     4.3.2 (432.47)
CoreWLANKit:     3.3.2 (332.36)
Menu Extra:     9.3.2 (932.35)
System Information:     9.0 (900.8)
IO80211 Family:     6.3 (630.35)
Diagnostics:     3.0 (300.40)
AirPort Utility:     6.3.2 (632.3)
When I go to System Preferences : Network, it says ‘Wi-Fi Off”.
Strangely, I did successfully get online via Safari on the MB but only once. Now, there is no internet access from the MB.
I can access internet with iPhone and iPad whose settings properly show the correct home Wi-Fi name, and I can use iTunes to pass docs from and to them when they are USB connected and just by Bluetooth.
Earlier that day, I had received a warning from a friend that his email account had been hacked. Later, whilst checking Spam folder (Yahoo), I inadvertently clicked an email from him, saw that it was indeed Spam, and quickly closed it again.
Could this have contained something that caused the above situation?
Any advice as to why this has happened and its implications, please? And how to get back to normal?
Many thanks,
Graham

I had the issue after upgrading from 10.7.3 to 10.7.4. It has persisted into Mountain Lion. Recently, my late 2011 15" MBP had its wifi card and cable replaced, along with the main logic board. The logic board was damaged by the repair staff in the process of disconnecting the wifi cable. A couple of days ago, my wifi started shutting off randomly but would return after a restart. Now I've got the "no wifi hardware installed" message again. I haven't checked System Profiler to see if the wifi card is listed. Previously when I had this message, it was not. So, yes, the hardware repair fixed the problem for about a month. And now it's back.
