Does Windows 7 Equalize Sound Output

Feb 12, 2012

I have an IR RC Helicopter that is controlled by IR transmitter that plugs into the audio out jack of my mobile phone (which runs an app that produces the audio signal, that the transmitter converts).

I've recorded the audio out of the app via the line-in on my computer. I get a nice signal that I can decode into the component information used to control the helicopter.

My problem is that when I playback the signal (via the transmitter, attached to my comps headphone jack) the helicopter won't respond.

I tried re-recording the audio of my computer by looping the headphone jack out back into the line-in (not sure if this is a good idea in terms of feedback). I can then record the signal output, which is similar to the source one but fairly distorted. Does windows 7 equalize sound output or something funny, and if so can I turn this off?

PC - Dual Sound Output

Aug 11, 2009

I have an HDMI lead coming out the Graphics card Radeon 4870 HDMI Vapor-X and straight into the HD TV, this works fine and the sound comes out of the TV when I play a video file.

I'd like to be able to play games on the computer with the "game" audio coming out of the PC speakers/headphones via the motherboard at the same time as playing video files through the TV.

Is this possible and if so how do I seperate the two audio devices in Windows 7?

Disable Sound Through HDMI Output?

Oct 24, 2011

When I connect my laptop to TV through HDMI cable, I get both video and audio from it to play on TV. And if I connect speakers to the headphones output I can't hear sound in speakers, the HDMI audio is still playing on TV. Is it possible somehow to disable the audio on HDMI so only the video will pass? Or maybe to make the sound from headphones output to play audio as well?

8400GS Kills Onboard Sound Output?

Jan 4, 2011

I will try and make my first post as informative and direct as possible. I am having an issue with installing a NVIDIA Geforce 8400 GS video card into an older HP Pavillion 6040n

Windows 7 Professional x64
Asus P5LP-LE motherboard w/onboard sound
Intel Core 2 Duo 6320 Processor, 1.86 Ghz
Seagate 7200 320GB Hard Drive
4 GB RAM (PNY but I don't remeber the speed of it)
Geforce 8400GS 512 MB graphics card with DVI and VGA outputs (no S-Video, NO HDMI outputs)
300W generic PSU

when I physically installed the graphics card into the PCIE slot and rebooted the computer the sound stopped working. the computer does not see any audio output devices that are installed. when I mouse over the small speaker in the bottom right corner there is a red x over the speaker, like it's muted, and it says "no audio output device is installed" When I remove the card and go back to using the integrated graphics card in the motherboard, the sound works fine. I am using the 3.5mm jack off the back of the motherboard to get to my desktop speakers.I have tried installing the latest drivers from NVIDIA, doing a clean install of the drivers (IE removing the old versions first)I did not let in install the NVIDIA HD audio driver that comes in the 260.99 driver I tried reinstalling both the Realtek R255 sound card driver and the older R235 Driver.Nothing I have tried has worked. Something interesting I have noticed is windows installs 4 generic High Definition Audio Devices. When I see them in Device Manager I delete the drivers and restart the computer, but every time I restart, there is still no sound, and windows once again installs 4 HD audio devices. Why would a graphics card render an onboard sound card inoperable? Would a clean install of windows 7 fix my problem? Did I go to cheap in selecting the 8400 GS? Could this be in IRQ conflict?

No Sound Output To Speakers / Headphones - All Drivers Working

Feb 13, 2009

All the drivers are working and windows is detecting everything just fine, I can even look under the volume adjustments and see the sound being produced. But I am getting no output to my speakers! I've read through a lot of forums and tried both xp and vista drivers along with the recommended 7 drivers, all work but I am getting no output through my integrated speakers.

I am running a Toshiba u205-5002 with a ACPI x86 motherboard and soundmax it just not working for me. I am at a loss of what to do. I don't get any program sounds whatsoever, no startup, nothing. All device managers say the devices are working properly and it detects the speakers just fine. I am also not getting any output to my headphone jack either. I am using the 32 bit 7000 build...

No Sound Output From Rear Speakers (Creative A500)

Sep 24, 2012

I recently bought Creative A500 5.1 surround sound speakers for my PC. I then bought an internal sound card as i only had 2 speaker inputs on my pc, but then found out that my motherboard has only 1 PCI slot. So i had to buy an external sound card for the surround sound to work (this one) I connected it all up, put the wires in the correct places, but the rear speakers do not play any sound. I know they work, as I put the rear jack into the front output to test them. If I go into sound, then try to configure it to 5.1 I don't have the option to select rear speakers. (picture of what i mean) I can't go into enhancements to select fill speakers either as the tab isn't showing up in properties. And also, as I'm using an external sound card (USB), nothing shows up in Realtek HD audio manager, so I'm not able to do it from there.

Have Realtek High Definition Sound But No Hdmi Output

Nov 20, 2009

I've upgraded from vista to 7 and I am getting no sound, I've searched, searched and tried alot of different things, I see alot of people on this forum with the same issues, but I've tried most of them. I've installed and unistalled all the different drivers from realtek, but no luck. I have realtek high definition sound but no hdmi output. In my device manager it says the sound driver is installed properly, but when I tried to test the sound it fails to test tone, I don't know if it has to deal with an audio codec. I have regular speaker that connect to a sound jack. At this point I am quite desperate. I've spent all night trying to figure this out.

TV Output Concerning Windows

Aug 21, 2011

Windows has a feature to allow you to output your computer to your HDTV right? (Via HDMI). But I'm building my new PC in a few months and was wondering if I was to connect my PC to my HDTV via HDMI, would it output to the TV during things like the BIOS and Windows setup? Or only if I tell ti to via Windows?

No Hdmi Output Windows 7

Jan 9, 2012

i've twice installed latest drivers GeForce 285.62 Driver , i've been into nvidia control panel and then setup multiple monitors & it only detects my other vga monitor not the hdmi one, i'm using a brand new hdmi cable & can confirm i've connected it to the correct hdmi connector on my monitor, it has 2 hdmi ports and i've tried both, when i go into device manager & display adapters there is only 1 adapter that says nvidia geforce gt 545, should there be another 1 for the hdmi? i'm out of options, i even work in i.t as a breakfix engineer coming across similar issues like this but i cannot deal with this & really need some help so i'm really hoping someone will help me out here i'm wondering if its anything to do with my other hardware such as the xeon cpu? (a longshot but i've only just built this pc & never built a xeon system before & would normally go for core i5 or core i7)

Windows 7 Hdmi Output Is Only Available When It Is Off

May 25, 2012

i have a dell core 2 duo with 3gb of ram, and an ati hd4650, when i boot up, both outputs get the boot up screens, when it gets into windows, the hdmi output appears to be unplugged(not available for selection, just not there) it is worth noting that it worked fine under vista, anyways, when i switch the source on my receiver, or turn it off, as long as it is plugged in, it then gets detected, and i can modify resolution, and apparently it is outputting sound as well, i cannot verify this because the receiver is OFF, tried various versions of the catalyst drivers, and one of them worked, until i went into the catalyst center to change something and it went back to what it was doing i feel it is something wrong with the windows side or the driver, ive tried upgrading to the x64 version, ive tried different cables, different ports/plugs, it just wont work, i have no idea where to look in the registry to change when it is detected, but when i turn off the receiver or switch off of that source, the monitor flickers and the output is detected, this is frustrating because i wanted all of my home machines to be on 7, and i really dont want to go back to vista.

How To Use A Phone's Output Audio In Windows

Jan 8, 2012

I had a grand vision of grandeur. I'm planning on buying a Nokia Lumia 900 running the Windows Phone 7 on it when the phone comes out soon. Being a designer, I had to design a dock to plug in the phone to charge and sync and the idea came: what if I could use my awesome stereo and my awesome Windows 7 to make the dock into an awesome home phone?

What it would be is a mic built into the dock that is connected to the phone so when someone calls me, I don't need to pick the phone up. And if I can with the Windows Phone, I can have the audio out from the call be recognized in Windows 7 as in audio input and I can have my puter's audio output to my awesome stereo to hear the call from my speakers.

The stickler is, as is with every grand vision of grandeur, can it happen? I don't know for sure what to do to get the audio out from the phone to connect with Windows 7.

Windows 7 Default Audio Output?

Jan 16, 2013

I have a minor issue with my laptop switching to the default speakers when it's put to sleep. It's only started doing this recently and I've made no configuration changes whatsoever. My laptop is connected to an audio receiver via HDMI which is never turned off. When I put my laptop to sleep (usually from within XBMC) the laptop no longer recognizes my receiver as an audio output and requires a log out/in to reconnect it. Like I said earlier, this has only started happening recently.

No Display Output During Windows 7 Update

Feb 19, 2013

I was installing a long list of Win7 updates on my PC when the display abruptly shut off during installation. I know there was an update for the Intel integrated graphics chip somewhere in that mess of updates. The PC has that integrated GPU plus a GTX660 (with fully updated drivers). I didn't want to restart the PC, but I am unsure of what to do next.

No Audio Output Device Is Installed. Windows 7?

Jul 20, 2011

English is not my first language so I'm not familiar with the Computer Science vocabulary. I've had a Pavilion dv9700, Model # dv9819wm, for approximately 2 years. My hard drive failed and the guys at my school were able to recover 60 GB of files but most of them don't have an ordinary format. They are just saved on a folder on my desktop. They installed Windows 7, (It was Windows Vista before the failure) and I've been having problems with the coprocessor and "ethernet" drivers. Yesterday I uninstalled the "ethernet" driver and when my laptop rebooted the audio driver was nowhere, (obviously I have no audio), which was surprising since that was not the one I uninstalled. My Sound device is not shown on Device Manager either. I uploaded some applications that identify missing drivers and apparently the sound driver is the newest one available. I got on BIOS and the sound button was enabled. I went to HP's website and the only audio drivers offered for my laptop model were for OS Vista. When I try to automatically install the driver from another HP application it says something like my "Compatibility..." is not permitting a correct installation. First, what is going on? and is there any way I can get my pictures and videos from those 60 GB into a normal

Windows 7 - How To Confirm 1080P Signals Output To TV

Nov 24, 2011

I just picked up a new graphics card HD6750 for my HTPC. I am then connecting the HTPC via HDMI to an 1080p LED TV. How do I ensure that I am sending an 1080p signal to my TV? My TV manual states that the tv supports: 1080P 1920 x 1080P. So I know the TV can handle it. Do I simply set the Display settings to 1080P 1920?
