My dv5-1225ca doesn't output sound when connected to my LG HDTV via a HDMI cable. I got the green bar flashing on any of the four devices (HDMI, speakers, headphones, SPDIF) as long as I change them as default. Sound just did not want to come out from HDMI or SPDIF on my TV. I wasted 6 hours in 3 days with the useless HP techs and tried everything they suggested, i.e. changing default device, update drivers, update BIOS, even system recovery to factory setting eventually. Nothing worked!
I asked each of the HP agents the same question: does my dv5-1225ca machine support such HDMI audio output? The answer was always yes! So I thought it is just bad luck getting a broken machine. Within 14 days of purchase, I exchanged it for another one. Same thing!!! I brought home a G60-324ca before and it worked (both picture and sound via one cable), so it is not a problem with my TV.
This is the setting of the dv5-1225ca:
AMD Athlon X2 QL-62
ATI Radeon HD 3200 RS780M intergrated graphic
Windows Vista 32 bit Home Premium
ATI Radeon HD 3200 Graphics
High Definition Audio Device
IDT High Definition Audio CODEC
One last thing, I tried installing the latest ATI Catalyst 9.5 driver. It just screwed things up: it didn't not recognize the HDMI Audio Device any more and showed it "not plug in". Green bar was no longer flashing.
Any help will be appreciated! Or at least tell me the true about the hardware: is the machine supposed to support HDMI vedio+audio? Is this a hardware problem or a software problem?
The next thing I am going to try is to install a XP dual boot and see if it is a Vista problem or not. Any suggestion?

Does anything show up on the TV at all?
I had a similar problem to this, before. Everything said "connected" except for the TV which just said "no input" or something like that.
Have you tried flipping around the ends of the cable?
It sounds stupid, I know, but it worked when everything but the TV was recognizing they were plugged in, haha.

I have a HP DV5 1011ea and recently upgraded to Windows 64. In the course of the upgrade, the NVIDIA graphics drivers were updated to the latest stable release (186). After this I lost the sound via HDMI to my TV, causing great annoyance when trying to watch Blu-Ray. In short, for whatever reason, the HDMI sound output does not seem to work properly on this NVIDIA release, even though the volume/signal bars on the Sound control panel indicate that sound should be outputted to the TV.
I uninstalled the driver and rolled back to a previous driver release and the sound came back. BUT, this was at the expense of DirectX which was downgraded at the same time from 11 to 10.
After much cursing I decided to install the latest Beta release of the NVIDIA drivers (195) - search the download section nvidia.co.uk for Beta and Archived drivers Much to my delight the sound came back and DirectX stays at 11, which is good. Just a couple of issues worth highlighting:
1. The driver is not completely compatible with the IDT control / windows sound in general - if you click on the Sound control panel you are warned that the NVIDIA HDMI driver has incompatibility issues & are questioned whether it should be disabled. I left this alone as frankly I can live with this if sound is played when watching Blu-Ray. I suspect that if the NVIDIA HDMI sound is disabled that no sound would come through the TV when watching BR and that the original problem would re-occur.
2. When the HDMI lead is unplugged from laptop, the screen on the laptop remains blank rather than "recovering". This means that the laptop needs to be put into sleep mode or shut down whilst watching the TV and then restarted when the HDMI lead is unplugged. I suspect that both of the above are likely to be ironed out in the next stable release, but who knows when that might be. In the meantime, the Beta release seems a good option to me – I suggest that you try it & see what you think. If you are not happy, then roll back the NVIDIA driver to that featured on HP website (release dated 11 2008, 60.1 MB, “18.104.22.16804 D Current”)

i, wow, so get this, I talked to the phillips rep about my two different philips hdtv's: 42pfl3704d/f7 and 32pfl3504d/f7 and according to phillips, it is not possible to input hdmi audio via an hmdi cable FROM a pc or notebook. One can use one hdmi cable to import both VIDEO and AUDIO if they are coming from a cable box or some non pc type component, however, only video can be brought in via hdmi on these tv's when importing from a pc. for audio, customers will need to plug the video from the pc into the hdmi 1 port (there are 3 hdmi ports) and then use the headphone jack from your pc/notebook and take the audio in through a left and right phono plug (rca plugs) on the back of the tv that says hdmi10-audio in.... wish i had known that. still, i wouldn't be suprised if it is possible to get the hdmi audio into the tv from a pc via only and hdmi cord, but this is probably the easiest workaround over some crazy thing microsoft or somebody has done to mess with philips...or philips is just behind the game. what do you think? thanks for your help. peace. things I had heard might work include installing some sort of nvidia hdmi hda codec or something...what about that? people are linux seem to have something. again my bios does not have any sort of hdmi audio choice, there is no mention of any kind of audio in my bios. Hi nvidia, I am writing because I think I got my playback devices back.
