Sony :: Z Type, Windows 7HDMI Sound Output ONLY Stereo
Aug 4, 2009
I've been Windows 7 now for quite a while and it's been great apart from the little brightness setting bug. There's also the issue of having no surround sound output via HDMI.
When I was running Vista using the stock audio/video drivers I've had no issues getting the HDMI (to my surround sound reciever via HDMI) to output surround sound, it just worked for whatever media I played.
Since switching to Windows 7, I've been unable to get any surround sound out at all, It's only outputting stereo. I've tried the various Realtek drivers and have had no luck, they don't even allow me to use HDMI sound output when the cable is connected!
Anyone else have this problem? or found a solution?
I'm running RC1 x86 on a Vaio Z (VGN-Z90S - original Jap. model). I've also tried it with earlier versions of 7 with no go, and I'm hesitant to try the RTM version. I kinda want to wait for another reformat until I get my key.
Anyone have surround on their Z through HDMI? (please let me know, what drivers/OS you're running.)
I have 2 identical VAIO laptops. Sorry don't remember the model. If important
I will check when come home. But they are last year model core 2 duo. Silver ones
One of laptops fall down. The screen is not functionning (just all kind of lines). It goes to windows prompt( I can see background of login box.
When I connect external screen, there is no output signal. First, I thought that something is really wrong with the board. FN F7 make no changes. But I decided to connect external screen to my second identical laptop. And it not gives any external signal. But when I login to windows I can switch to external with FN F7. Looks like F7 is managed by software inside the Windows. Logically output from the laptop should be during the boot.
What are my options? Don't want to put a nice hardware in the garbage.
It worked yesterday but as of this morning no sound. The Realtek highDef sound device has the current driver and is identified as operational by the Win 8.1 device manager, but no sound comes out from any source. Rolling back the driver to an earlier version did result in a pulse of static during the changeover but still no output.
As side note the Devices and Printers button is no longer working in Classic Shell.
I have no sound, although everything tests fine and volume is changing. No sound from speakers or output to headphones. I have tried all invetigations, everything is OK including Windows Audio, set to automatic.
HP Envy 15 Product Number A9R05PA#ABG running Windows 7 64 bit.
Also, while sitting in its usual well ventilated space it has gone in to thermal shutdown a few times when I wandered off, and froze once on startup. I am now backing up everything ...
Suddenly my computer has no sound what so ever. It doesnt work when I plug in headphones, either. When I hold the mouse over the sound icon in the bottom right corner of the screen it says, "No Audio Output Device is Enabled."
I have Windows 7 Home Premium 64-bit Service Pack 1. My computer's product number is XZ046UA#ABA.
Do I need to install a new driver, or something else?
My U330P is running Windows 7 with the latest drivers for both the Intel HD video module and the Realtek audio chip. I would like to connect my machine to a TV via HDMI and have it both act both as the display as well as the audio playback device (i.e. TV speakers should blare, not the ones in my Ideapad).
The thing is, I don't have said TV yet and if what I want to do is not possible, I will not bother buying it. I already did look around in Control Panel -> Sound -> Playback in order to find out whether there's an option to set the HDMI port as a playback device but found nothing. I also have the playback devices menu display disconnected and deactivated devices, but the only thing showing is the built-in stereo speakers. The listings in my device manager don't suggest something like a "digital sound whatnot" either.
So in general whether the audio signal can be rerouted to the HDMI output connector on a U330P.
I have a dv7-7270ca notebook and since a restart due to windows 8 updates I now have a red x on the speaker icon. I installed the HP driver for this model but it has an error in device manager that says:
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
I did run an audio test using the shut down-F2 and passed and could hear the sounds in the test.
Actually it happend about 2 months ago. The sound coming out of the speaker as well as the sound when I was using a headphone was just not right, barely any low frequency sound. In the beginning I can fix this by reinstalling the audio driver. Then after a week or so the same problem would occur again, and I had to reinstall the driver. After several times, reinstalling the audio driver cannot solve the problem anymore. Besides if I plug in the headphone after I muted the laptop, it should unmute automatically right? Well that does not happen and it's still muted.
I bought a Roline DP to HDMI cable hoping to be able to watch HD content in my livingroom and not having to plug an extra audio cable as DP should carry sound too.
When I do the same as on the youtube video, I get the following settings in the control panels: [URL] ....
But there's no sound coming out of the TV. I've tried it on my SyncMaster PC/TV Screen and on my Samsung TV in the living room. On the TV in the living room, the windows audio manager shows the device, but it cannot be selected as show above. It stays grey.
I've got a T420s with discrete nVidia Optimus graphics (Quadro NVS4200M). Driver version is 22.214.171.124 for nVidia HD-Audio and 126.96.36.19996 for NVS 4200M. This information comes from the device manager. I installed my system from scratch and used ThinkVantage System Update 4.
Where the problem comes from? I could only imagine that the cable isn't capable of carrying audio, but that seems rather illogic, does it?
I recently received this acer laptop as a gift. Right from the first time I started it I noticed issues with the sound. With any audio that played there were crackling noises.The crackling got worse and worse so I Decided to restart the laptop and then the sound stopped working altogether.I tried reinstalling the Realtek HD audio drivers that came with the laptop but that didn't work and I still got a "No Audio Output Device is Installed" message in the bottom corner.
I tried reinstalling the drivers AGAIN, and the sound worked. All seemed well until I woke up the next day with no sound yet again.I then tried downloading new drivers from the realtek website, even these drivers didn't work. The only solution to the problem seemed to be basically uninstalling and reinstalling the realtek drivers until they worked, and even then, the sound would still crackle horrendously.After getting fed up with this issue I tried to refresh windows, and even this didn't work.I have tried everything I can think of .....
I bought a z690 with a blu-ray recorder for $1550 at SonyStyle. The problem: it connects to my high def Vizio Television, but there is no sound coming out of the television speakers, only the Sony speakers.
It says there is an HDMI audio driver but it is not connected, even though it is. Keep in mind - I did upgrade to Windows 7. It was working with Windows Vista
I have an AW series laptop and a Philips HDTV 720P not the full1080p, what seems to be the problem is that when i plug my hd cable into my laptop and then into the LCD the picture dosent display correctley and I have to drag windows off screen on my laptop to display on the HD telly, how to correct this and get it to show whats on my laptop on the lcd?
I have a Studio 17 and added a Dell 370 bluetooth card so I can use my bluetooth mouse and it works fine.
I saw a pair of Motorola Bluetooth stereo headphones, and I'm wondering if these would allow me to listen to my mp3's using Winamp, or if I go into a voice chat room if I can use the bluetooth headphones ?
I would like to try them for listening to my mp3's and I think the Dell 370 is A2DP compatible but not sure about that either, I cant find that on the Dell spec sheet. The headphones are Motorola S805 stereo bluetooth phones.
If it does work, does it have as good sound as a wired headset would ?
As everybody probably knows Vista doesn't support/have Stereo Mix, so in order to get it to work I followed a guide from somewhere (could of been here) that linked to other Sigmatel drivers and then installed them in XP compatibility mode,
however, having done that i've now totally lost the use of the inbuilt mic...has anyone else had this problem? Is there a way of fixing this or am I limited to having one or the other
I have a Sony VGN-Z36GD. I am having problems with my sound. When I try and record something all I get is a hissing sound when I play it back. When I use Skype I can hear the person I am talking to but they cannot hear me. My laptop says everything is working yet it is not.
Ive been using a 40 inch HDTV ever since I received my Z about a month ago. I had to move recently, and now when i attempt to use the display it looks very strange, almost as if someone turned the digital vibrance or contrast setting up all the way. The text looks strange, and it is overall unpleasant to look at. I checked all of the settings and everything is the same as before, and tried varying the resolution and color settings. I can't figure it out!
I can take a picture if that would help explain better. I also checked the TV's settings and I do not believe that is the issue.
I also tried reinstalling the NVIDIA drivers from sonys website to no avail.
I have a Sony Vaio FW laptop with a HDMI output, when i had vista i could plugin my hdmi output in to my TV hdmi input and immediatly see my computer display on my TV. As soon as i upgraded to Win 7 Ultimate 64 bit, when i plugin the hdmi cable nothing happens, i am unable to get my tv and laptop to notice each other, Win 7 doesnt seem to notice at all.
I have an HP DV6700 Laptop, and I recently installed Windows 7 Professional (64 bit) (The full version from MSDN academic alliance, not the release candidate). A few days afterward, I had an issue where my speaker icon has a red "x" over it, and when I hover over it it says "no audio output device is installed". The funny thing is that the speakers worked after windows update installed an update, then they stopped a few days later, and I cannot for the life of me get the speakers to work again!
I find the volume output to be extremely inadequate. All of my volume are at max. I click the little speaker icon in the taskbar to make sure everything (speakers, system sounds, application sounds) is max and sure it enough...they are.
