Hello. You could try using Windows System Restore to undo the changes you made, but probably you will have to download and install a fresh copy of your Conexant audio driver from the Vostro 1015 support page.
Be sure to first select your operating system using the small blue Change OS button, then expand the Audio category and get the driver.
If you need more help please include the name of your operating system in your reply.

  • How to set preferred audio output device on macbook pro mavericks

    I've got a pair of Harman Kardon bluetooth soundsticks that I use as my living room speakers. Some time ago, I connected my macbook pro to them via bluetooth, and now whenever I restart my macbook or move it away from the apartment and then move it back, it automatically finds the soundsticks, connects to it via bluetooth, and sets it as the default sound output device.
    I would like the soundsticks to remain connected whenever they're within range, but I want my macbook's internal speakers to be the default sound output even if the soundsticks are connected. I can't seem to set output device preferences in the sound preferences panel.
    thanks,
    - will

  • How to chang audio-output-device(s) in Windwos 8

    Hi,
    currently I’m working on an application that starts by changing the audio-output-device and ends with re-setting the old one.
    On Windows XP I do this by changing the Registry-entry “Sound-Mapper” and it works quite well.
    I hopefully assume it works on all Windows Systems from XP to Windows 7.
    The background is that our program is supposed to play certain multi-channel sounds over an external USB-multichannel-soundcard and it should switch to that device on start. To actually play the sounds we use the AxWindowsMediaPlayer-Class
    to integrate the Windows-Media-Player in our application.
    However, on Windows 8, it is possible to set multiple Audio-Outputs and the Windows-Media-player has a setting to choose from them (under Options). I was unable to use the Registry-trick to switch the output-device and I could not find
    a way to programmatically tell the AxWindowsMediaPlayer to choose the USB-soundcard as an output.
    Is there a Way to programmatically(c#) ether change the audio-output-device(s) in Windos8 or to tell
    AxWindowsMediaPlayer to use a certain device?
    Thank you.

    Hi Kristin,
    I think your reply pushed me in the right direction.
    The waveOutOpen-function is part of the
    winmm.dll-API and I think, that API is the solution to my Problem.
    Unfortunately I am stuck at this point. I tried mciSendString and mciSendComand. Both are cappable of playing sound, but I am unable to change the output Device.
    This is my c# code to open a WAV-File via mciSendCommand:
    MCI_OPEN_PARMS open = new MCI_OPEN_PARMS();
    open.wDeviceID = 0;//this is somehow ignored
    open.lpstrDeviceType = Marshal.StringToHGlobalAnsi("waveaudio");
    open.lpstrElementName = Marshal.StringToHGlobalAnsi(@"test.wav");
    IntPtr ptr = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(MCI_OPEN_PARMS)));
    Marshal.StructureToPtr(open, ptr, false);
    mciSendCommand(Convert.ToUInt32(textBox2.Text),               
    MCI_OPEN,              
    MCI_WAIT | MCI_OPEN_TYPE | MCI_OPEN_ELEMENT,              
    ptr);
    Afterwards I use mciSendCommand to start the playing of the sound, which works fine, but no matter what I enter in the “open.wDeviceID”-Line, I always get sound over
    the default output.
    I use waveOutGetDevCaps to get the number and kind of the output-Devices and this works fine.

  • Changing audio output device for currently running program

    I'm not sure where to put this question, but all my searching hasn't seemed to find an answer...
    If I have a program running, iTunes, VLC, a game, whatever, and want to change audio output from say Line Out to Headphones, I have to restart the program for the change to take effect. Is this by design/normal or am I missing something somewhere?

    this is actually a quiet significant issue. There is no way in Flash to select the audio output device.
    Today  people have regular speakers and a separate headset. They all use the  speakers for music and the headset for voice. Skype i.e. has the option  to choose audio output device and its really handy, because
    you dont  have to bother to set the default device to the headset everytime you  want to use it.
    If you set the default device to the headset all other apps will send their audio  output to the headset - which is not what you want either.
    So people  really want to leave the default device set to the speakers and not to  the headset.

    JRT 2.1 / Nokia UI API updated to version 1.4:
                AudioOutputControl extension for controlling which audio output device, for example the device loudspeaker or earpiece, is used to play back audio
    This really is an issue.

  • Selecting audio output device in iTunes.

    I currently have two sound cards installed.
    My computer is defaulting to playing sound through one of them, but I would like to play iTunes through the other.
    Is there a way to select the audio output device that iTunes outputs to?
    I have no been able to find the option anywhere.
    Thanks!

    Hi 
             What program are you refering to ??  Or do you mean you have deleted the driver for your Audio/output device ??

  • Changing audio output device

    Hi,
    I'm building an application that uses LCCS for video calls.
    We've encountered an issue that we couldn't find any solution for and we believe is crucial.
    Since the current version doesn't support AEC, all our users uses headphones to use the service.
    The problem is, that to the best of my knowledge, if you plug-in USB headset, there is no way to make flash switch to using them instead of the regular audio output. If that is true,this means that assuming a user has USB headphones, even if we will add a note in the application saying "use headset to reduce echo" - that won't help as the user has no way of using his headset with our application.
    Am i missing something? please tell me I am.
    Thanks,
    Itzik.

  • Add Audio Output Device / Text Chat to Firefox Hello.

    This isn't a question, more a suggestion.
    What would really make Hello awesome would be the ability to select that audio output device used for conversations rather than it simply using the windows default, the audio output device used for alert (ringing) as people would probably want ringing to be on main speakers and the conversation on something like a headset. And of course text chat, so links and other textual information can be easily sent.

    Thanks Fred. I understand Hello is in early days so of course I don't expect it to be all singing all dancing right from day one, I'm sure it will continue to evolve. So far however I'm impressed, the audio/video quality is excellent and barely any latency. Top notch stuff.

  • No Audio Output Device is Installed (intermittent)

    Model: HP Pavilion dv6810us
    OS: Windows Vista Home Premium (32 bit)
    I have the above laptop, which has been giving me some troubles as of late. First the DVD Rom drive disappeared from the device manager,then the keyboard stopped working right, then the audio output device vanished. Well, yesterday I disassembled the entire thing, cleaned up all the gunk and cat hair that had accumulated on the inside and threw it all back together.
    The good news is the keyboard works again, it's not overheating anymore, and the CD/DVD-Rom drive is back and functional, and the sound came back.
    The bad news is the sound has gone kaput again and it again says there is no audio output device installed. I tried reinstalling the drivers, and that didn't work. It said couldn't install the drivers because it couldn't locate the device. Every once in a while, the sound comes back, but then it usually goes away again.
    Soooo, is there a fix for this or am I going to have to break down and buy a new lap top and/or new components? I usually have pretty good experience with Altec Lansing speakers. But, now all that shows up in my Device Manager is the Bluetooth Hands-Free Audio and Bluetooth Stereo Sound....which doesn't really... give me any sound at all.
    Thanks in advance.

    Its easy! Your sound drivers are corrupted.
    Just do the steps:
    1. Delete the sound drivers from the Device Manager
    2. Restart your pc
    3. Reinstall the drivers.
    Note:1. Disable Internet before starting these steps.
              2. After restart When the windows tries to install drivers, stop/cancel it.

  • Hi there, can anyone tell me how to make make Garageband ignore HDMI as an audio output-device on a 2013 Mac Mini? Now it keeps on prompting me: Do you want want to use the HDMI device (monitor without audio) for audio output? Thanks in advance, Grtz T.

    Hi there,
    Can anyone tell me how to make make Garageband ignore HDMI as an audio output-device on a 2013 Mac mini i7 using an Apogee jam as an input for bass and a Behringer USB DAC with RCA audio output? Now it keeps on prompting me: Do you want want to use the HDMI device (monitor without audio) for audio output? I'm also suffering massive audio lag issues with the Apogee jam after waking the mini from sleepmode, wich pretty much renders it useless.
    Thanks in advance,
    Grtz T.

    I think the easiest way to do this is to have the EyeTV app running in one user account and sent via HDMI to the TV, and use a separate user account for Screen Sharing. Both logins can be active at the same time and with Lion you can connect via screen sharing to which ever login you need.
    With regards to the Mac video resolution changing, when it is not the current input on your AV receiver. This is 'normal', if the Mac sees no signal it drops down the a lower level. What you need is to buy a HDMI Detective Plus which tricks the Mac in to always seeing a signal and hence it will not drop down the resolution. See http://www.gefen.com/kvm/dproduct.jsp?prod_id=8005
    The Mac mini does have an IR receiver. This can be used with the EyeTV app, iTunes, and similar. Yes I believe EyeTV would run for prolonged periods quite happily, it is has been around for a long time and had most of the rough edges polished off. However one issue you will have to deal with is that it does not automatically update its program guide data. For this you might have to write or modify an AppleScript. Elgato support or their user forums will be a lot of help.
    You can set EyeTV to convert recordings to an iTunes (Apple TV) compatible format and then delete them from EyeTV.
    The HDMI Detective should solve your handshaking problems.

  • Changing the iTunes audio output device

    Question: Is there a way to assign sound output device for iTunes 9 that's different than the default audio device?
    I use Windows 7 64bit. I have USB headphones and speaker outputs on my system. Both are detected and both can be assigned to be the working default sound choice. I prefer all sounds from all apps on my computer to go thru my headphones (my default audio device), EXCEPT iTunes, which I want to go thru my speakers so that everyone in the room can hear music.
    The only way I can make a iTunes work through the speakers while the headset is assigned the default role is to go into sound management, then assign the speakers to default and then restart iTunes. This is super annoying.
    Desired: I would like to adjust the sound output device from within iTunes, or else find a mixer application that allows me to assign outputs for each application individually.
    Hardware: i7 920 cpu, asus p6t motherboard, 6GB Ram, GTX 285 graphics, creative SB x-fi soundcard. Drivers auto discovered on install and appear to be functional.
    Thank you.

    Thanks for the tip. I've downloaded the trial, but unfortunately the demo they provide doesn't match with what I downloaded... I can't figure out how to make it work. I select the apps, but then there's no "apply settings" button. Hmm...
    I'll mess with it more... but yes, this is the idea of what I need. I'd happy pay for it even.

  • Is there a way to have Firefox respect the default audio output device when it has been changed while Firefox is open?

    I have been a Firefox user for many years and I still use it as my primary browser. One problem that has bothered me for years is the fact that when Firefox is open and I change my default audio output device, Firefox doesn't respect that change and continues playing audio through the device that was originally being used. Even if you stop the audio and continue playing, the output device doesn't change.
    Is there any way this can be configured in Firefox? Now if I listen to music online (e.g. Soundcloud) I always use Chrome since it's respects the default audio output device change even while in the middle of playing audio.
    Reproduce:
    1. Start playing audio (e.g. from a YouTube video; HTML5 and Flash are affected)
    2. Change your default audio output device
    3. Audio will continue to play from original output device
    Thanks!

    This is the same issue that has plagued me for years. I always thought that this was a Flash plugin issue, but it does occur on HTML5 as well. A friend of mine verified that this does not occur in Linux, but only on Windows. It would be great to have this fixed, as it's honestly the only thing that's making me use Chrome all the time, as I don't want to have multiple browsers open.

  • How can you choose which audio output device to use?

    I currently have my system set up to have two different active audio output playback devices, Speakers and Headphones. By default, applications play on the default audio output device, which is set to Speakers on my computer. However, I am wanting to play iTunes on my Headphones output while all other applications are running on the default Speakers output. In Windows Media Player, there is a dropdown to select which output device the application streams to. Is there a way to make iTunes do this, either in the Preferences menu, by using a plugin, or installing a third-party application that overrides which output applications use?

    Under Utility you will find the Configurazione MIDI Audio.app  The name is in italian on my Mac but you should find it in your system language. The icon is a Piano Keyboard.
