Installed A Driver Called AmdEHCI Now HDMI Port's Audio Is Failing?
May 4, 2012
So I was having some audio problems with my computer so I figured updating the drivers would be the best bet. I decided I'd use one of those programs that can check your driver and download the driver you need. I followed the instructions and installed what seems to be called AmdEHCI onto my computer. Now whenever I turn on my HDTV which I have connected via the HDMI on my ATI Raedon 6950 the audio claims that it is not connected. Now every time I want audio to come out of my HDMI I have to disable to display and then re-enable it. I used to be able to turn my TV on and off whenever I wanted and I would still have audio functioning properly.Something that caught my attention was that when I left the properties window opened for the HDMI audio and then turned on my TV I would get a message that says "The device you are configuring has been removed." even though I haven't touched anything other than the power button on my TV to turn it on.

I have two HP Pavillion 9700US 17" series laptops and either of the HDMI ports have audio. Can the sound card be changed if that is where the issue is.

I'm operating on a desktop intel dq35j0 and clean installed window 7 ultimate.
in device manager two errors appeared
pci serial port driver not installed ( code28)

checked hardware id's in device manager as follows
pcven_8086&dev_29b7&subsys_4f4a8086&rev_02 for serial port driver
and the same hardware id for the simple com controller
Ive tried to search these drivers on intel site but get lost as to wher I may find these drivers.
the same issue is a problem on two other pc's after cleaninstall of win 7
1.) is an hp dx2000 nt
here the network controller driver has not installed
the hardware id is
pciven_0675&dev_1702&subsys_6692&rev_00
2.) is a hp pavillion dv6 (1125ei) notebook
here an "unknown device" driver not loaded
the hardware id is

When listing the installed programs there is a column called 'location'. How and where does this come from in the installation program? In other words in Visual Studio 2008 where does one put this entry for the installation to cause it to show up?

I have a new pc with a Gigabyte GA-H67MA-UD2H-B3 motherboard and I plugged a Microsoft 600 Wired Keyboard into the rear port (designated for KB/Mouse by Gigabyte). The keyboard works in the BIOS, but when Windows 7 loads, the num lock light switches on, then Windows 7 says that "Driver not installed properly". In the Devices & Printers window, it shows an icon of the keyboard with a yellow exclamation mark and says "hardware not available". However, mouse continues to work. This happens in all the rear USB ports. If I plug the keyboard in the front port, Windows recognizes the keyboard, install the correct driver and it works! All the USB ports work fine otherwise (tested with thumb drive as well as mouse). I also tried with a Logitech K120 wired keyboard which also had the same problem.!!

I'm trying to hook up my TV with my computer, and for the most part it's working. The video goes through and I get how to control it and everything. The only thing not working is the sound.
I'm using an HDMI to HDMI cable, and like I said the video is fine. Also, when the cable is plugged into my boyfriend's laptop, the sound comes out of the TV.
So this must mean the problem is with my computer specifically. Although, this computer is only a month old, so I wouldn't think anything is out of date.

Last night my new laptop arrived (XPS), still getting used to windows 7 etc... but i thought i would watch something through my t.v. Plugged HDMI cable in back of laptop straight in to t.v, changed the source and straight away i had a lovely sharpe picture of my deskop instantly.... or so i thought
im getting the middle part of my screen fine - but it is cropped so i cant see the tool bar (its too low) and the desktop icons are only veiwable if i move them closer in screen! Ideally i want to have identical screens on both so i can use both at sam time, but currently i can only view either or atm? and the t.v one being crop means i can use it as a computer (No toolbar etc..)
I could figure this out on XP but windows 7 seems beyond me atm!

My laptop is several years old and I haven't had the need, until now, to use the HDMI port. I plugged a Kodak video camera into the port and the camera is supposed to come on automatically and begin the download of software to use with the camera. This doesn't happen and I get no error message.

Currently having a lot of trouble to even get any sound out of stereo mix. I'm wanting to record sound from my PC but I'm not too sure if I can with the current set up I have. I'm using my Samsung TV which is plugged into the HDMI port on my PC and using the speakers already in/on the TV. I've went to the properties of stereo mix changed the "playback through this device" to my TV and I don't get any sound coming from Stereo mix on any program and the green bars aren't going up and down either.

I recorded premium channel movies on a Dell Inspiron n5110 laptop. I used a SiliconDust HD Home Rum CableCard tuner. The movies play fine on the laptop screen. When I plug in into the TV via it's HDMI port, it does not play back the premium channels recordings. This is the message. "Display Driver Error - The video playback device does not support playback of protected content."

Yesterday, I bought a 10m HDMI cable and I plug it from my TV to my CPU. Everything was fine. The only thing was one of the games which requires Port COM1 and COM2 could not access.
I tried disabling the HDMI sound and it worked. Is there any way to change the COM port for the HDMI sound? I tried going settings on Windows and could not find any.
I just need the sound because it's a music game, from the Arcade. Everything was perfect before plugging my computer to the HDMI.

I installed my audio driver for my gigabyte ud3 b3 motherboard. I got the driver from gigabyte's website. It is the 64 bit windows 7 version. Now I have realtek hd audio manager installed. I have a set of speakers plugged in which I know work because i plug the cord into my iphone and the speakers work great. Now I plug into the green input hole (which by the way, I should say that everything worked great before I recently reinstalled windows 7). When playing music I look at the mixer and see that all programs playing the music and the speakers have the green bar going up and down to the music. But the bar that says system sounds does not report any sound ( no green bar going up and down).

I have a HTPC setup. PC includes an ASUS MB with on-board video and audio, including options for either separated analog 7.1 audio out or HDMI out (among other output options). Current setup routes Audio and Video via HDMI to Pioneer VSX-1020 A/V receiver, and routes video from there to HDTV via another HDMI cable. OS is Win7 Ultimate x64, w/SP1.
Exact model for mb is here: ASUS M4A88TD-V EVO/USB3 AM3
When I play audio files, the receiver can fake the signal into all 5 channels (I don't have a sub, so the .1 is not relevant here), so there's no issue of the receiver not accessing the available speakers.
The main issue is this: When I look into the Sound Control Panel, under Playback Devices, the active/default device is ATI HDMI Output. Also listed are Speakers (not plugged in), Realtek Digital Output and Realtek Digitial Output (Optical). I do not have any analog cables plugged in, nor do I have an S/PDIF (optical/coax) connected. The HDMI works, but only gives me the option of Stereo (2ch). When I go to the Configure screen for the ATI HDMI Output, I see a list of Audio Channels, but that list ONLY contains Stereo.

I'm working on fixing a Toshiba Satellite laptop. It is a very years old and I reformatted it and tried Windows XP and Windows 7. I installed the Realtek audio drivers straight from the website (HD Audio Driver) but no luck. The Windows Update driver gives me a RTKHDAudio BSOD and I tried fixing that with some advice online to no avail.

I think I got all my drivers figured out except for the sound card. I've tried the Lenovo site but it says Vista should use the Microsoft drivers and those don't seem to be working. In Device Manager I see "Multimedia Audio Controller" with the ! icon by it. "The drivers for this device are not installed. (Code 28). There is no driver selected for the device information set or element. To find a driver for this device, click Update Driver." I search for updates and find nothing... I tried the XP version but that didn't work.

i built myself a new computer and it has an ASUS Rampage 3 Formula motherboard which has:SupremeFX X-Fi 2 built-in 8-Channel High Definition Audio CODEC
- Supports : Jack-detection, Multi-streaming, Front Panel Jack-retasking Audio Feature :
- X-Fi� Xtreme Fidelity™
- EAX� Advanced™ HD 5.0
- THX� TruStudio PRO™
- Creative ALchemy
- Blu-ray audio layer Content Protection
- Optical S/PDIF out port(s) at back panel
I install the Realtek audio driver software and i get access to all my cool EAX advanced HD, THX truStudio etc.. things on that list BUT i get crackling noises every now and again when playing music/games whatever.
However i uninstall the audio driver software and i get no crackling sound when i listen to music or such, but i cannot access any of the features anymore.Whats going on here? its not the speakers or headphones i use, they have been tested on multiple devices, this only happens after the audio driver is installed and the audio features are activated.
My PC spec is:
CPU: Intel i7 980 3.33Ghz 12mb cache 6 core
GPU: 2x GTX 460 1GB
MB: Asus Rampage III Formula
RAM: A-Data Plus v2.0 XPG 2GB 1866Mhz 8-8-8-24 x3 in triple channel
SSD: OCZ agility ~400-500mb read&write
HDD: 1TB 7500RPM WD caviar black
this is all brand new, i just finished building it all a while ago, so there is like no crap running in the background like viruses or unneeded programs.my speakers are just small desktop 2W speakers, and i also use iPhone headphones, i have tried using the front jack on my pc & the rear jack (one that says "front" and is a light green colour) i get the noises nomatter if its headphones or speakers.
if i chage audio drive to nvidea from my graphics card and plug speakers into audio jack on my monitor which gets the HDMI audio from the GPU i get perfect sound.Uninstalling Realtek audio driver makes my pc use a microsoft audio driver it must have default, but it sounds fine.i just cant do ANY of the audio features available from the motherboard without it. and i worry its not HDMI/cinematic surround without this?

My laptop won't install my USB mouse when i plugged it into my second USB port. It only works in my first USB port when i first restored my windows 7. I tested using my pendrive in the second port and its working just fine. However, when i tried to use my mouse in the second port, it wont work, even the broadband which I am trying to use in that port.I recalled clicking the option "skip searching for drivers from windows update" coz i was on a slow net at that time and was kinda in a hurry, so yeah. Is there any way to make my laptop re-install the drivers in it coz my wild guess is that I chose not to install it last time so it wont try to auto install the drivers again.

I am trying to get audio from my PC via HDMI into my Marantz NR1402 AV Amp and then into my panasonic plasma.the plasma is picking up the desktop (so the signal is going thru the amp ok but the amp is not receiving any sound. In the Nvidea Control panel Set up Digital Audio it recognises The marantz under HDMI but in the configure section "open windows sound setting" it only shows speakers (not plugged in) & Digital Audio (S/pdif) Default device (i am showing hidden & disconnected devices).I have opened the pc case and noticed that I have a two pin cable from the 9500gt going to the Spdif on motherboard & a cable running from the soundcard to the front sockets on the pc case.

I installed Windows 7 yesterday and at first I had no audio to my TV via the HDMI cable. I adjusted the settings via the sound icon on the taskbar, playback tab, changing whether the speakers or the Digital Output Device (HDMI), Sigmatel High Definition Audio Codec was the default. Eventually I got it to work.
Today, however it has stopped working again and no matter what changes I make, nothing works. When I right click on the playback device Digital Output Device (HDMI) and choose TEST, I get the message: Failed to play test tone. All sound comes through the laptop speakers.
I went to device manager and checked the driver for the codec and it was up to date.
When I was using Vista, to get the audio all I had to do was plug in the HDMI cable and the sound automatically went through the TV.
Does anyone have any ideas how to solve this?
