[HELP] G470 HDMI audio problem

Hello guys! I'm currently using Lenovo G470 since 4 years and i discover that my HDMI audio is not working (but display is fine) my ATI is broke since 2 years ago and i'm using the UMA graphics on BIOS. i tried all the steps available on this forum (re-install the OEM chipset and integrated video/audio driver) and it didn't help at all. while investigating on ibmxHDMI folder of OEM driver C:\Drivers\Intel Onboard Graphics Driver\ibxHDMI>ls -a
. .. IntcDAuC.dll IntcDAud.cat IntcDAud.inf IntcDAud.sysAnd based from Installation_Readme.txt***************************************************************************
For Intel(R) Display Audio Driver:
1. Click "Start" then right click on "Computer" button and then click on
properties.
2. Click on "Advanced system setting" option and then click on "Continue"
in "user account control" window to goto "system properties" page
3. Click on "Hardware" Tab, and select "Device Manager"
button.
4. Double click on "Intel(R) Display Audio".
2. Select the "Driver" tab and then click on the "Driver Details" button.
3. The function driver (intchdmi.sys) version should be listed on this
screen.I should expect intchdmi.sys on exist on ibxHDMI folder. also OEM Driver: http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/lenovo-g470-notebook/downloads/DS011506 [PS: Already checked the playback device and obviously i can't see HDMI output from there]

Some HDMI adapters won't work with the new MacBook Pros if they aren't compliant with the 1.1a version or later of the DisplayPort spec. There are some adapters out there that aren't fully compatible.
I believe you need to have i5 or i7 Macbook Pro for audio feature through mini displayport.
2011 models should have sound with proper adapter but I'm not sure about 2010 models.
Good luck

HP Pavilion dv9218tx Notebook PC and HDMI audio problem with Sony TV and Windows 7

Sound does not come through with the HDMI connection and, on investigation, there is no HDMI audio driver/option.
Noting that there seemed to be an issue with windows 7 and HDMI audio which is addressed by updating the BIOS and the connexant sound driver I have done so to no effect.
The Sony TV is recognised as a standard monitor in the devices for graphics but not for audio
Suggestions as to why HDMI does not appear - including as a disabled service - and what to do t get is available?

Hello everyone,

Bootcamp Windows 7 HDMI audio problem

Hello,
I have problem sound over HDMI with my MBP late 2013 13'' model A1502 on Windows 7 with Bootcamp.
I've installed Windows following Bootcamp wizard from mac and creating bootable WIN7 usb with all support drivers on it. After this I've noticed that there is no sound on my tv when i connect it to my MBP. I've searched a bit more about this problem and I found that the latest graphics drivers might solve this problem so I've updated Intel® Iris™ Graphics 5100 directly from Intel's official web page and after the restart voila I have sound to my TV.
After some time I was configuring my resolutions and I unplugged the HDMI cable and then I put it back again and the sound stopped. At first I was thinking that it is something with the default audio device settings and when I went into the control panel audio settings I've noticed that the HDMI audio device is missing.
I've thinkered a bit and found out that when I unplug the hdmi cable in device manager's "Sound, video and game controllers" the Intel(R) Display Audio is removed from the list but when i put back the HDMI cable it dosent appear in that list. Instead of that in section System devices the High Definition Audio Controller have warning sign and have the following error message: This device cannot start. (Code 10).
You can check it on this image below:
However, when I reboot the MBP with the HDMI from my TV pluged into it it is all OK. So my guess is that it may be some driver service problem or some compatibillity problem with Cirrus Logic CS4208 (AB 93) audio controller. Currently it is working like this but It's very annoying to reboot each time when I wan't to connect it to my TV...
Any suggestions how to fix this problem are welcomed.
Thanks

reformat and zero your partition or chkdsk
make sure Windows has 15GB or more free space to work with
I have Macs and PCs all runnng 7 and even 8.
Maybe your iMac hard drive or even if SSD is where the fault lies.
boot from Widows DVD and check your system

HDMI Audio Problems with HPEnvy

Hi,
When I connect the HDMI port to an Elgato Game Capture Card, there is video, but no audio. Examining the audio options, the HDMI audio driver is not even loaded.
I have the latest drivers, and in fact, when connecting to other devidces (such as a Samsung TV or audio enabled monitor) using the HDMI port, the audio works fine, and the HDMI HD audio driver is available in the audio menus.
I know that some people on other windows 8.1 platforms have been able to do this, but not me. I would love a solution.
Currently, I am using the audio from the earphone port, but the sound is less good than I would like, and of course there is an additional rats nest of cables this way.
Thanks so much for any help.
Best,
Scott

MSI Media Live - HDMI audio problem

[split off from https://forum-en.msi.com/index.php?topic=113127.0 - Stu]
Has anyone gotten this to work? I've got mine to where Vista says I have a HDMI Output device installed and set to be the default device, but it just doesn't play any sound at all.
I've tried:
- Latest Realtek HD drivers from MSI's website (R1.67)
- Latest Realtek HD drivers from Realtek's website (R2.21)
- Latest BIOS update from MSI website (1.63)
- Enabling 8 Channel option in BIOS
- Using HDMI cable and TV port that I know already work (using them for my Xbox 360)
- Was using Vista 64-bit, now using fresh install of Vista 32-bit (was hoping the problem was driver incompatibility with 64-bit, but I guess I was wrong)

So you have Realtek HDMI audio enabled and set as default?
Check in Realtek HD Audio Manager, under HDMI tab, that output is not muted.

Hdmi audio problems on dv6t on Windows 7

I am having a very strange issue when I connect my laptop to my stereo receiver with an HDMI cable. I use my laptop to watch movies from netflix's websites on my entertainment system. I connect the laptop to my stereo receiver using an HDMI cable while I am watching movies. This used to not be a problem. However, I tried to change some audio settings on my laptop to get dolby digital from the laptop. I believe I made my changes in the SPDIF (Digital Out via HP Dock) audio device. Since then, everything has gone awry. I no longer get audio through my stereo system, but even stranger now, anytime I connect the laptop to the receiver while a netflix movie is playing, my whole wireless network is taken down. I am at a loss as to why this is happening. If anyone can help me with this, I would really appreciate it. Is there anyway to restore my audio defaults so I can get back to how things were?

Have you tried MS System Restore to revert back to a date before you made the settings changes? It is in Start, All Programs,Accesories,System Tools_System Restore.

U330 HDMI Audio Problems

I have begun to recently use my hdmi port more and have thus been encountering problems. Before when I had set it up it would display on my tv with audio coming from the tv. Now when I use it, it displays on the tv but no audio works. I have hdmi set as the default audio device like before when it has worked. Any help in getting this sound to work would be appreciated. Thanks.

try to re-install or update sound drivers and make sure the cable %100 works ( well-connected )

HDMI Audio Problems

I bought my Mac Book Pro back in August of this year and I have had no issues so far with it until now. I am trying to get the audio to play through my hdmi cable that I just bought for my tv, but it won't. All of the options are in the output and HIDI settings for it but whenever I click on those settings it goes right back to the internal speakers. Any help to resolve this issue would be great!

Open your Sound preferences, choose Output tab. See if you have a sound device you need to select.

Hdmi audio problem

Hi,
Newbie here with a question.
I can't get audio anymore from my hdmi input. So I switched to regular rca input and it works, but of course no HD available.
So I'm going to go buy a new hdmi cable, but from problems in the past, I suspect the TV hdmi circuit may have an audio issue.
If that becomes the case, how can I hook up my fios hd dvr to the tv so that I can get HD ?
I know nothing about component video, I see there is a component video output on the fios dvr, and I also have a component input on my tv.
If i hook up cables to those, will I get HD and sound ?
Any ideas ?
Thanks Much.
Floyd

Yes, you can use the component connections for the video, and the audio connections for the sound, and you will receive an HD picture.
I would doubt that the HDMI cable would fail. Before you do anything else, turn off the STB, remove the power plug, wait 30 seconds, plug it back in, turn it on, and see if you get any audio. The Motorola STBs that Verizon use occasionally get themselves kinda confused in a number of areas, and removing the power frequently fixes it (until something gets it confused again...).
If removing the power doesn't work, do you have a second HD TV that you could hook up to the existing STB and cable? If that works it isn't the cable, its the first TV - just trying to make sure the cable is really the culprit. Or of course it could be the STB, in which case you need to contact Verizon for a replacement.
If you wind up needing to get a new HDMI cable, don't go buy one of those over-priced things at places like Best Buy or Circuit City, unless you just have to have it today. Try www.monoprice.com or one of the other web sellers of HDMI cables, you can usually get one for 10% to 25% of the cost at one of the big box stores, and it will work just as well.
And finally, if you hook up the component and sound connections, you may find that you are perfectly satisfied with the results, and decide to just leave it that way. Not everyone agrees that HDMI is better than component, some feel just the opposite.

Dv7-2078ca HDMI audio problems

I recently updated my ATI video drivers and when I try connecting my laptop to my TV i get this dialoge box

Also when I go to the Playback tab of the sound devices while the TV is plugged in this is what I see.

The video displays fine but with no sound.
Is there anyway to have both video and audio transmit as with the old drivers?
Should I reinstall to an older version?

Please Help: Q700 - HDMI TV Problems

Hi there,
I just received my Q700 in the mail, and I am excited to start using it; however, when I connected my Philips HDMI-compatible TV to the Q700 and set it up, I can get an image on the TV... but the image is verry blurred with what can best be described as "digital fuzz" over top what I am supposed to see. It almost seems like the display is scrambled somewhat.
I was just on the phone with Customer Support for a VERY long time... to no avail, so I really hope that someone can help me here. All I got out of Customer support was that apparently "Philips" brand TVs aren't supported by the Q700 - which seems sort of astonishing (if true), as that wipes out an entire brand of compatability.
If anyone from Lenovo - or anyone else with some insight - could please help me out, it would be greatly appreciated. I need to know if this system is going to suit my needs, as it seems that it has the ability to.
Thanks in advance,
- Jake

Seems like some possibly related information at these links. You might want to read thru them. Also, have you tried a different HDMI cable? I know there are several versions out there. I am using an HDMI 1.3 cable with my Q700 and Sharp TV and it works fine.

Logic Pro Wont Start Up.... HELP. Core AUDIO Problems

OK here goes.. I have been working with Logic since December. I have a lot of project that I am working on and I have this movie sound track that is my biggest thing. Anyway, I have been using logic pro 8 with my Motu Ultralite. Its been working just fine. I got a Mbox yesterday because one of the producers I am working with on this movie uses protools so I got the Mbox to work in Protools 08. I finished my session in Logic...> hooked up the Mbox and tested it out with Protools 8. It worked fine. Now today I tried to launch logic and it would not open. It gets to "initiallizing Core audio" and then it crashes and quits. Can someone help me on this one. I have a deadline to meet today and I have the finished project and cant access my Logic. I am going crazy seriously. Can anyone help. I have did the if You need a crash report I will post one here. PLEASE HELP!!!!
PJ

Ive been using Logic 8 and FirePod for some time now and this semester enrolled in a Pro tools 8 class at Foothill using my Mbox. Things seems to be working with both logic and protools, so far other than exporting my sessions over to OMF format, mainly a vanilla import, no effects, automation, etc gets thru, but I digress....
Check to make sure that your system still see's the Motu device in the system profiler, and open the system log inside the console application within the Utilities folder and then watch what gets reported to the console while firing up Logic.
To get more help, include what os version your running and the hardware; Mac Pro, Macbook, etc... Stating the version of the programs, and of course have you applied system updates on the your machine....
Im running a Mac Pro Intel with 10.5.6 with all the latest updates......

HELP: S10-3 Audio Problem - Dolby Headphone

I have recently purchased a Lenovo S10-3 laptop.
One of the features that I noticed is virtual headphone surround sound by Dolby.
The problem that I have is that when I enable it, the volume becomes unbalanced. The left headphone speaker plays twice as loud as the right one. The sound quality is much better with it on and I really want to use it, but I cannot because of this problem. I tried individually adjusting speaker volume, but there is a significant loss of audio quality and surround effect if i do so, not to mention that the sound then becomes unbalanced again if I use the volume control.
I am using Windows 7 and the Win7 Drivers supplied with the laptop.
TL;DR: Left Speaker Louder than Right with Dolby Headphone Surround enabled.

This happens with any and all headphones.
My Realtek Control Panel looks different from that picture.
My one looks like this. (for both versions of the windows 7 driver)
The driver from the website is version 6.0.1.5989
The driver supplied with the laptop is version 6.0.1.6113
I am not sure whether this feature exists in earlier drivers and whether the problem exists in Windows XP.
My ancient PC sound card only works properly in XP, but I would not expect a new PC to have problems with windows 7 drivers.
Below is the closest matching image that I could find online. While mine looks slightly different, this is the feature that I am having problems with.
Link to picture
The feature works similarly to Creative's CMSS 3D, but in addition to expanding the sound, the centre channel (L+R : Vocals and bass) seem to be panned to the left, and that is the problem.
The driver from the website does not have this feature. It seems it was included in the newer version, but not coded properly.

Can someone help with an audio problem that is driving me crackers!!

hi, i have seen lots of comments about windows sound issues, my problem is it sometimes says i have speakers installed and they are working (but have no sound) and other times (when i turn it back on) it says no device installed/not plugged in etc.... now i know from reading previous posts this is an issue for loads of people, my question really is, can i use speakers that connect via usb rather than 3.5mm jack, and does anyone think this will make any difference? my dad has suggested fitting a new sound card? will that sort it out, have only had my pc for a week, and it is under warranty but i have to pay the postage to return it (not bought from a shop directly if that makes sense) i have to date spent about 8 hours googling, reinstalling drivers, everything you could possibly think off and nothing has changed!!!! speakers work as have tried them in my DS and the front headphone jack is not working either i have installed windows updates and read somewhere that might be an issue? is there any point doing a system restore and if so how will that work, and will the photos i have uploaded still be saved if i restore to apoint before they were put on? sorry but im not very technically minded!!
please help me as im slowly going grey!!! i have a pavilion p6203

I know you must be very frustrated with the sound issue. It sounds like you've done a lot of research and leg work to figure out what the problem is with little success. I would not restore the system unless you have backup copies of anything you downloaded (just in case) As I read....you've uninstalled drivers and rebooted to reinstall and downloaded updates to Win 7 Have you reviewed all the suggestions at the attached Link? I can't explain why the headphones connection does not work but maybe go look at your main sound setup in control panel to see if there is an issue with the settings there? Look to see if there is something going on inside the "Hardware and Sound" icon. These are guesses as I can't understand as well why you've not hit on the appropriate solution. Let me know when you solve this issue what it was. Regards

Catalyst & HDMI audio: problem when turning TV off

Hi everyone,
I've got two PCs with AMD E-350 FPU, one is a laptop running Windows 7 and the other is a nettop running Arch Linux (using Catalyst as a driver for the GPU). On both of them, I'm experiencing a similar problem with sound:
When turning on the computer and the TV, everything works just fine, including sound. However, if I turn off the TV (without disconnecting the HDMI cable) the following happens:
Arch: no sound anymore, even if I turn the TV back on. No visible changes in alsamixer.
Windows: sound through internal speakers. ATI HDMI sound device now shows up as 'Disconnected', even if I turn the TV back on.
Disconnecting the HDMI cable and then inserting it back (while the TV is on again) fixes the problem on both computer, and so does rebooting the computer.
However, even though this seems to not be a Linux-related problem (being etiher a problem with TV's firmware or ATI GPU), I wonder if anyone knows of a more elegant (preferably software, of course ) solution than reconnecting the cable each time I want to turn off my TV and then turn it back on?
Last edited by popoffka (2012-06-01 10:29:36)

I have the same issue in Windows. If I turn-off the TV and turn it back on, there is no sound. Because I have no other sound devices (disabled the others in BIOS setup), the speaker icon shows a red "x". The playback devices screen says HDMI is "unplugged." I have to restart the system or unplug/reconnect the HDMI cord to get sound to come back.
