Audio device Apowersoft went silent

Identical issue to: http://in.answers.yahoo.com/question/index?qid=20120126083013AAY0n2N
That is, there are 2 playback devices one is "Apowersoft" and other is "Conexant Smart audio HD". One day back Apowersoft was working,but now it is not. Everything seems fine (driver up to date, volume maxed, test shows bars for volume but no sound,etc.)
I disabled Apowersoft and am able to get sound, but the volume is low and periodically the sound starts making noise and I have to fiddle with the sound controls to get it normal again.
Also tried:
If you are using windows 7
click start <> in the search box type in audio
from the list click on <> Find and fix audio playback problems.
But of course it reports everythuing is fine... grrr...
Solved!
Go to Solution.

Quick work arounds (that got the marginal sound) was to: Disable the Apowersoft device. A marginally better solution was to Control Pannel=>Hardware and Sound=>Mange Audio Devices
In this window right click on the Speakers (Conexant Cocoa II...) and select Set as Default Communication Device. Then right click on the device again and select Set as Default Device.
Again this marginally works as the volume is low and the noise problem periodically shows up.

MY "No Audio device detected" Solut

Before I begin, I would like to say if this doesn't help you out I am sorry. My goal is for this method to at least help out one person, if so I would feel content in passing on what had worked for me to this community. I would like to also mention my card worked fine on my Win XP setup but after i switched back to XP i started getting errors such as "...audio device supported not detected..." whenever i would try to use the mediasource applications or even do the driver update for my Audigy 2 ZS card. Here is the method that finally worked for me, because there is no way i was going to go through the minatinous job of having to test different pci slots to get this card to work.
. I did a cleansweep of my audio drivers, directions for different operating systems can be found at this url ( http://ask.americas.creative.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=ww_english,Company={CEAE26D-879-4C00-AC9F-03BC258F7B70},VARSET=ws:http://us.creative.com,case=72 ) once you reboot your system after the end of the cleansweep it will locate your card automatically ignore the found new hardware prompts pertaining to your soundcard by pressing cancel on it (or them if you have more than one prompt) and go on to step 2.
2. After that i did a normal cd installation for my audigy 2 zs card installing both regular drivers and the mediasource applications (just to make sure). After the installation finalized I was asked to reboot again which should be done at this point.
3. Once windows loaded back up It located my soundcard and I was presented with the "Found New Hardware" prompts again. At this time for each prompt that came up I picked that I wanted to choose where to find the correct files which i believe is the Recommended choice by Windows which was one of two choices in this area. From there it takes you to another screen where there are checkboxes to choose where you want windows to search for the correct file(s). I chose for both of my found new hardware prompts (if you have more than one, they will show after you finish off the the first one...meaning you will do this procedure more than one time because they will only come up one at a time) for it to search my CD Dri've which still had my creative disc in it so it could search the CD for the correct files (and it should find them).
Then
I proceeded to do a manual install of the drivers as well (yes im installing over an installation, it sounds stupid i know..but it worked for me) by exploring the CD and running the program located in the Audio/Drivers folder called CTZAPXX.exe (CDDRIVE:\Audio\Drivers\CTZAPXX.exe). Make sure the Update Option selected is Driver Installation and the Driver Type is WDM Drivers and also i checked "Overwrite existing shared Creative audio driver files". Then just click OK and click through any warnings that may come up telling the program you want to proceed still. Once that is done it will ask you to reboot again, at this time you may do so.
4. After Windows loads up this time i have my driver update ready which is located here ( http://us.creative.com/support/downloads/ ) according to card type and operating system (since peoples configurations differ this is something that will have to be searched for independently). Normally when i would just click this file to update my drivers it would unpack and then give me the infamous "...audio device supported not detected..." error but after those steps i took, it actually worked for me and went into the installation. Then i believe it asks for another reboot i might be mistaken but after that good sign of it actually installing all my applications work without a problem now; and everything seems perfectly fine for the time being
Sorry for being long winded, but again if you are a person stuck in this rut or just now have encountered this problem and have tried almost everything, this could be worth a try. I am running win 2000 so there might be some discepancy but you never know until you try. If this doesnt help you all good luck in continuing to find answers hopefully something will come along.

<div class="lia">ReCogNeYez,<div class="lia">Might be a little late, but this worked perfectly for me. You can now?rest safe in the knowledge that your advice has helped someone out. Now I can finally get back to watching Red Dwarf : )<div class="lia">Cheers mate!<div class="lia">George

Inspiron 1525 not able to select internal mic for webcam, nor is it showing up on Control Panel, Sound, Audio Devices

Initial problem was Dell Webcam video recording records no sound.
In Control Panel, Device Manager, Sound Video and Game Controllers there are two High Definition Audio Devices listed: Location 1 (Internal High Definition Audio Bus) - I deduce this is the internal mic; and Location 2 (Internal High Definition Audio Bus) - I deduce this is external microphone jack. Both have the same driver version.
The Control Panel, Sound, Recordings Tab showed 2 devices that looked identical except the bars that show green with volume were only on the first one, which is also the default one, and would detect sound if you got real close to the webcam mic when talking. Both devices displayed as 'working'.
Accessories, Sound Recorder recordings are silent no matter how close you get to internal webcam mic.
Dell WebCam Audio Source tab has two selections, both reading Microphone (3 - High Definition Audio Device). Both selections record sound with the EXTERNAL MIC jack. There is no way to select the internal webcam mic, it is not an option.
Per instructions found on the web, I uninstalled the first device only in Device Manager and rebooted. The same driver version as before was installed. But now the settings have changed. Device Mgr still shows Loc 1 and Loc 2. However, under the Sound, Recordings tab there are still 2 devices, but the first one says 'currently unavailable' , is still the default, and the sound bars that go green for audio testing are on the SECOND device now instead of the first one. If you check the Properties for each device, they BOTH are showing the same location Location 2 (Internal High Definition Audio Bus), i.e., the external mic jack. Loc 1 device (built in mic) is not showing up!!
Accessories Sound Recorder works with the EXTERNAL mic. (How does it know which one to use, it's not giving me a choice?)
So the Location 1 device (internal mic) is not showing up anywhere besides the device manager. I want to use the internal mic for skype and webcam. Somehow I need to get the Loc 1 device to show up on the Sound - Recording tab and in the Webcam Audio Source list? What do I do?
Thank you in advance for your help.

This is Vista.
Go to the Inspiron 1525 support page. Find the small blue "Change OS" and click on the arrow. Select Vista.Then download and install these 3 items with a restart between each one.
1. Dell System Software in the System Utilities category.
2. Intel Mobile Chipset in the Chipset category.
3. Sigmatel audio driver in the Audio category.
See if it works any better after you get the Sigmatel driver installed.

"No Audio Device Installed" in Windows Vista.

Back in september 2011 I mysteriously lost my audio. I have a red X over my speaker icon in my system tray. When I put the cursor over the speaker icon I get this message "No Audio Device Installed". I went to the HP Customer web page and found the audio driver: Realtek High Definition Audio Version 6.0.1.5548 (sp37324.exe). I downloaded the program and saved it to my download folder. I put a short cut to it on my desktop. The only way I can get sound is whenever I turn on my computer I right click the desktop short cut and run as Administrator and install the program. My sound comes on. It works as long as I keep the computer on. Whenever I restart the computer I'm back to the red X over the speaker icon.
Now, Windows Update has sent me (on 3 occassions the last couple of weeks) an "optional update"...the Realtek High Definition Audio. Each time I download it and install it and do a restart,but I get the same red X over the speaker icon. It's Ground Hog Day!
My question: Is it safe to uninstall the Realtek High Definition Audio driver and reinstall the sp37324.exe without totally sending my audio into a Black Hole? BTW,I don't have a recovery disk.
I hope someone on this forum can help me. I've exhausted all avenues.
This question was solved.
View Solution.

Hi,
My suggetion: Totally uninstall it, reboot the machine and install it again. You can uninstall it from
   Control panel > Device Manager
   It should be under Sound ...
   Right click it & Uninstall

Fix for Missing Audio Device in WinXP S

My sound card disappeared from the Sounds and Audio Devices Properties panel. I tried cleansweeping and reinstalling to no effect. I could watch my card disappear from the panel as Windows went through startup after I reinstalled it. My card , a Sound Blaster Li've!, was listed under the hardware tab but the drivers were listed as "Driver installed but not started". Creative Diagnostics said I passed the hardware detection test but failed the driver tests. I am using the drivers from the Li'veDrvUni-Pack(ENG) version .0.0..
I found this fix after searching with Google. The site is www.annoyances.org/exec/forum/winxpt/t06642744. It resolved my problem. I did use DH Driver Cleaner Pro to remove any Creative drivers. You need to know that the hardware scan and reinstall in step 6 can take several minutes. I also removed hidden copies of my Creative devices in step 5. The revealed hidden devices have greyed icons next to them.
Sincerely,
Weasel
re: sound device errorThursday, April 2, 2005 at 6:02 amPosted by Ven <FONT size=-2>(<I> messages posted</I>)
RE>Hello to all,
I got much useful information from this topic, but none of them resolved my sound
problem. I use Windows XP SP2 on an Asus V7V8X and a Creative SB Audigy. I also tried
removing the SB card and enabling the built in VIA AC 97 without success.
Then I tried removing and adding back the Plug and Play Software Device Enumerator
as you suggested without success.
Then I went further reinstalling some of the kernel sound drivers and that resolved
the issue in my case so I describe my ste
ps.
First I suggest everyone to create a System Restore point to have something to return
in case of something goes wrong. You can boot XP to safe mode by pressing F8 at the
beginning of the Windows startup and select Safe Mode if the system doesn?t start
in normal mode and use System Restore there to go back to the working configuration.
Then try these steps only if the others mentioned here don?t help. I had everything
ok in Device Manager and every driver was running that should, compared to an other
working system, but the symptom was that there was no sound coming out from the sound
card. Everything was OK in the Device Manager, but in the Sounds and Audio Devices
Control Panel there was only the Voice recording option on the Voice tab, and the
MIDI music playback (without the sound card being in the list) on the Audio tab acti've.
The others like Voice playback, Sound playback, Sound recording and everything on
the Volume tab was grayed out.
. Create the restore point.
2. On the System Properties panel, Advanced tab, Environment Variables button, under
the User variables click New and create a variable named devmgr_show_nonpresent_devices
with the value of .
3. Open the Device Manager and select Show hidden devices from the View menu.
4. Under the Sound, video and game controllers group, find your sound card(s) and
disable it/them (don?t need to uninstall).
5. Then uninstall the following devices:
- Microsoft Kernel Audio Splitter
- Microsoft Kernel System Audio Device
- Microsoft Kernel Wave Audio Mixer
- Microsoft WINMM WDM Audio Compatibility Driver
6. Select Scan for hardware changes from the Action menu. Now the system should redetect
and reinstall the deleted devices automatically. You may get non signed driver warnings,
click continue.
7. Enable the devices you disabled in step 4. You may need to restart the computer.
The problem should be disappeared, you should be able to play sounds.
Good luck!

Hi
You should check if the microphone has not been disabled.
Go to control panel -> sound -> recording tab
There you should make a right click and should enable the both options called show hidden devices and show disabled devices.
Now you should see 2 microphone entries; one internal mic and second should belong to the external mic jack.
If you want to use the internal mic then mark it as default device.
Cheers

CANT USE BLUETOOTH HEADSET AS AUDIO DEVICE

I just got a bluetooth headset today, paired it with my imac, went into teh sound settings, then selected it as my audio input and output device. was working fine all day then all of a sudden it stopped working and no matter what i do it will not show up in the sound setting to let me choose it as a audio device.
It does however show up in bluetooth prefences as connected/paired etc. what can i do to fix this? i am on 10.4.2 with all the latest updates and have the 20" imac.
thanks

I am experiencing this problem also. Strangely, I had my headset working properly, with no problems at all. Then, for no reason, the headset stopped working. I switched to another bluetooth headset and the new one worked properly. I also used a third headset, but it seems that the system is not properly clearing information about each headset. Now none work at all.
I have deleted all from bluetooth preferences, repaired one. The pairing appears to work properly, but the headset never shows up in the Audio section of System Preferences and cannot be used with Skype. I am at my wits end. I have repaired preferences. Shut down and restarted. Reinstalled Skype. Trashed Skype preferences. You name it I have tried it. I cannot get any of my 3 bluetooth headsets working now.
Please someone help.

AMD High Definition Audio Device Not Plugged In (HP Pavilion dv6-6b09sa)

I have just booted up my HP Pavilion dv6-6b09sa (running on Windows 7) laptop to find that the sound icon has a red cross next to it and it claims that 'No speakers or headphones are plugged in'. In the Control Panel it states that the AMD High Definition Audio Device is Not Plugged In. As far as I know, I've done nothing to cause this.I have already tried:System restore to yesterday at 10pm;Instalation of a TDI driver from the HP website, however I do not know how to edit/disable/delete the old driver. I'm completely clueless about these things. Please help, I'm at a complete loss.

This happened to me too. I own an HP Pavilion dv7-1135nr (Windows Vista). The internal hard drive stopped working, I took it to a computer repair shop, they put in a new internal hard drive, asked Microsoft for a key code and jump started the laptop. I took it home with me yesterday, watched a few videos and wondered why the sound wasn't working. The volume light on the laptop base was indicated as red (which meant the volume was off, even when the volume on the laptop screen was on). The only way I was able to hear sounds from videos was when I put my ear phones on.
I read somebody say that this happened to them and they restarted/rebooted their computer. I did that and, expectedly, it didn't work. I came across this page, opened up "Device Manager," opened up "Sound, Video and Game Controllers." Right-clicked the "IDT Device" and then uninstalled it. My laptop then restarted and thankfully the sound was back up. I didn't need to download anything or right click the "IDT Installer" or "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" or any of that. It thankfully came back without me having to do any of that. I restarted/rebooted my computer to see if it was a fluke, and thankfully it worked again. Now I don't have to use my ear phones. My ears didn't like being pumped with sound, even when it was on low. My "Digital Display Audio" is still not checked green. It says that it's "not plugged in." But hopefully I won't run into this problem again in the future. Because if I'm a week or two or a month removed, the repair people I initially went to for my internal hard drive problem, will say that this was a separate issue caused by me and will charge me extra, when it was in fact caused by them (not maliciously of course, I guess this kind of thing happens when you replace a hard drive, as do a lot of other things which I'm not beginning to see). Thanks DavidPK.

Satellite P30-145: Don't have an audio device in 'Sounds and Audio devices'

Hi guys,
I've only just fixed one problem with the help of one fantastic member but now I have another!
All of a sudden my speakers decide not to work!! I checked the volume etc and alll was fine but when I went in control panel>sounds and audio devices it says I don't have an audio device!!!
It worked fine this morning and I havn't done anything that could have done this.
These problems I'm having are all spontaneous, I don't know what's going on!
Does anyone know how I can fix this and does anyone suspect virus activity? (I have done a scan which said I don't have any)
I use a P30-145
Many thanks

Hi
Did you check the device manager?? Is the sound card listed properly in the device manager or some yellow exclamation marks appear?
Did you try to reinstall the sound driver? If not, please try it.
Of course I would also recommend to update the anti virus applications and to scan the system for virus and malware

Thankpad W530 and Docking Station - missing audio device???

I needed to set up a new Thinkpad Minii Dock Plus Series 3/USB with my W530.
First, there was a problem that the computer woldn't "seat" in the docking station. After calling Lenovo Tech support, and not getting anywhere, I individually pressed the "prongs" that stick up from the docking station. There was a loud "click" and several small thingies dropped down into the docking station. After that, the laptop fit right in the way it's supposed to.
I thought I was done, but I noticed an error message on my screen about a device driver error. The Lenovo Technician had me go to control panel > system > device manager..... right click on the machine name, and then click on "scan for hardware changes".
Device Manager didn't show any errors, but doing this generated an error box that said:
Device driver software was not successfully installed
Unidentified device --- device unplugged
High Definition Audio Controller -- ready to use
NVIDIA High Definition Audio --- ready to use
What do I do now? Is my docking station defective? Do I need to plug something into the docking station for this update to complete? The Lenovo tech had no idea what I might do, other than to call on Monday for "level 2 techs".
As a related issue when I went to update Windows, the following update was to be installed:
NVIDIA Corporation - Audio Device, Other hardware - NVIDIA High Definition Audio 3.9 MB
When I try to install this update, I get:
Code 800F020B Windows Update encounterd an unknown error
I think all of this is connected, but I don't see how it might have anything to do with the docking station.
As to the docking station, I tested the power connection (green light is on), a USB port (works), the audio out connection (speakers work fine, with no crackling sound), and the Ethernet connection (works). I haven't yet tried connecting an additional monitor, but that would have nothing to do with audio....

This is the Windows update that will not install:
NVIDIA Corporation - Audio Device, Other hardware - NVIDIA High Definition Audio
Installation date: ‎5/‎11/‎2013 2:14 PM
Installation status: Failed
Error details: Code 800F020B
Update type: Optional
NVIDIA Corporation Audio Device, Other hardware software update released in July, 2012
More information:
http://sysdev.microsoft.com/support/default.aspx
Help and Support:
http://support.microsoft.com/select/?target=hub
Any idea of how the docking station might be causing this?
All updates were done prior to installing the docking station.
Now I have this "problem" (that might be no big deal - I don't understand what's going on.

Elitebook 2540p Motherboard changed. Integrated motherboard IDT audio device missing in windows 7.

Hi,
Old situation:
(I recently changed motherboard for my computer Elitebook 2540p. When i installed windows 7 to my computer the computer doesn't list any audio devices in device manager page. I've checked bios for any faulty settings and they are all set right. Theres no yellow marks in device list either and all drivers seems to be installed.)
New situation:
Installed windows 7 again and computer found / installed audio devices normally. I tested computer for hours to play audio from it and everything worked fine. I restarted computer several times / re installed battery to the computer. On one restart the computers audio quick mute button below the screen appeared to be orange and the sound speaker icon in windows was marked as X. I check device list again from device manager and there was no audio devices listed (No sound devices at all). After that i restarted computer and before the computer started downloadin windows i pressed the mute button and it turned blue. I then went to windows and sound devices / sound was working again.
Old situation:
I have motherboard integrated IDT audio device.
When i try to install audio drivers from hp site for 2540p i get "Your system does not meet the minimum requirements for this update." And the device manager doesnt list any IDT audio devices.
I then installed xp and the computer found IDT audio device normally and the sounds are working correct.
New situation:
After i did new windows 7 install and all my audio drivers installed / devices showed in device list / audio worked i downloaded audio drivers from HP driver site and installed them to the computer.
Audio problems has not been occured again after my HP screen mute button turned to orange / Windows sound speaker was marked as X / Computer didn´t find any audio devices.
Currently waiting if the problem occurs again and trying to think what would cause this ( Hardware problem or software)? And how to fix it permanently.
Any help for this problem?

Dv6, Sound Icon has an X, no audio devices installed

I have a dv6 running on windows 7 and the sound has not been working for me the past couple of days (since Sunday actually). The sound icon is displaying a red X, and its telling me no speakers or headphones are plugged in. I have tried to do everything it seems like. I went to the volume control options and the “all devices currently playing sound” and “the default communication device” are both checked. I went to “manage audio devices” and it says no audio devices are installed. I went to Administrative tools, clicked on services and “audio service” is nowhere to be found. So I tried reinstall the audio driver, to update the audio driver, BIOS update before installing an audio driver and still nothing. Matter of fact, every time I tried to download another audio driver, I received a message saying “_ExitError: Error=Error in installation, Call to GetClassDevs” which I have no clue what that means. I tried also to go to “device manager” to see if something that’s supposed to be checked off, which might not have been checked off, but there was absolutely nothing being displayed in the “device manager.”
Basically, can someone please help me out? I’d really appreciate it. I’ve read lots of other posts and they’re not helping me so I’m getting a little desperate.

Wow, sounds like you've done some great troubleshooting with all the things you've tried.
Perhaps something happened Sunday to mess up your sound.
Have you thought of a system restore? From the document, Using Microsoft System Restore:
System Restore is a software program available in all versions of Windows 7. System Restore automatically creates restore points, a memory of the system files and settings on the computer at a particular point in time. You can also create a restore point yourself. Then, when you use System Restore to restore your computer to a point in time before an issue began, System Restore returns your computer to the files and settings from the restore point. Your personal files and documents are not affected.
It's just a thought, but it might help.

Satellite L50-A00V Notebook missing compatible High Def Audio Device Driver

Hi
I bought a Toshiba Satellite 15.6" L50-A00V Notebook
Features
PROCESSOR: 2.4GHz Intel Core i7-4700MQ Quad Core Processor
SCREEN SIZE: 15.6" Display
RAM: 8GB RAM
HDD: 750GB HDD
GRAPHICS: nVIDIA GeForce GT 740M 2GB With Optimus + Intel HD 4600 Graphics
OS: Genuine Windows 8 (64Bit)
Bluetooth: Toshiba Bluetooth V4.0 (High Speed)
LAN: 1Gbps LAN
Wireless Connectivity: Intel 802.11 b?g?n
Connector: HDMI?USB3.0
Running windows 8 now upgraded to 8.1
since the minute I brought this notebook home a couple days ago its had driver issues and toshiba service station was nothing but a PITA it did work and nor did any of the other bloated software that came with it.. later when upgrading to 8.1 hoping that would fix a few probs, it made my driver situation worse..
anyways i have removed everything via a clean install (but left the recovery partitions etc for safe keep, and made a recover disc) anyways even after clean install i am still missing the High Definition Audio Device driver.. in device manager I get a exclamation mark next to it..
the other drivers that were missing i had downloaded their drivers from the manufacture and they all were fixed accept this driver.. i bekieve its a realtek driver, which I went to the site and their latest driver didnt help..
can anyone please help find a working driver please, im trying my best not to send it back, but if i cant get its drivers working, then the hell with it, im send it back monday morning and claiming a refund...
so please if anyone can save me the hassle of claiming a refund, i would really appreciate it..
thanks

Hi
The notebook seems to be released for Australian market.
I did not find the Win 8.1 drivers on the Toshiba Australian driver page but only Windows 8 drivers.
However, it seems that the sound card was made by Realtek and the Realtek HD audio manager should be installed.
Try this driver which was released on Toshiba EU driver page for the similar notebook models: [Realtek Semiconductor Corporation v 6.0.1.7023 Windows 8.1 - 64 Bit|http://www.toshiba.eu/innovation/download_driver_details.jsp?service=EU&selCategory =2&selFamily=2&selSeries=178&selProduct=7948&selSh ortMod=null&language=13&selOS=46&selType=all&yearu pload=&monthupload=&dayupload=&useDate=null&mode=a llMachines&search=&action=search&macId=&country=al l&selectedLanguage=13&type=all&page=2&ID=88586&OSI D=46&driverLanguage=42]
Generally speaking I would recommend you to download and to install the common Windows 8.1 64bit drivers from the Toshiba EU driver page because such drivers are missing on Australian driver website.
Would recommend you to install the Intel chipset driver as well as the nVidia driver because the HD audio can be related to the nVidia graphic chip too.

Problems with sound drivers - audio device on high definition audio bus

i turned on my computer one day and the sound was gone. no "speaker" icon in the lower right-hand corner of the screen; no choices available via the "control panel: sounds and audio devices" icon. when i went to device manager, i saw "audio device on high definition audio bus" had a yellow exclamation mark. i saw some sites suggested downloading the realtek high definition audio, but that didn't seem to work -- and now i don't see the audio device on high definition audio line either.
any ideas? from what i've read, i gather this is a somewhat common problem but no solid way to fix this. i know something similar has happened to me a year ago but i was able to fix it somehow.
Solved!

Hello,
Have you tried installing the latest audio device drivers for your ThinkPad? If so, did that solve the problem?
