Hi Guys,

I really need some help with this one.

I purchased a new PC, with a Gigabyte GA-H61MA-D2V motherboard that has on board realtek audio, I also purchased a nvidia geforce GT630 graphics card which has a built in audio processor and hdmi connection which is going to my LG 42PL6010 tv.

I've installed drivers for chipset, audio, graphics, but I'm unable to get any sound out of the HDMI port. I've set the default play back device as as the tv in control panel - sound. Choosing to test shows the audio bars moving but no sound comes out.

I've checked bios settings, tried with only audio drivers, or only graphics drivers, no joy.

I've tested the cable and tv with a hdmi equipped laptop, so can rule those out as a possible cause.

many thanks

Ive had the same issue before. You must set the hdmi audio as default then when you disconnect it the cable it will be back to normal. I dont know why it does that. But just go to sound properties right click hdmi and set as default that should then fix it? Worked for me anyway.

perhaps you must enable sound in the actual graphics card settings? check within nvidia application.

That's what I said above... Attaching a picture so you can see exactly what I'm talking about....

Also beyond that, if you double click on the sound device that you had open in your screenshot, and click on the advanced tab, try a lower setting. some TV's can't understand the super high settings such as 24 bit / 192000 Hz. 16 bit / 48000 Hz is pretty much industry standard though.

For me to get mine working, i have to have the HDMI Cable plugged in to the TV + Graphics Card, turn my PC on when its all connected and make sure the TV in on the HDMI Channel.

If i plug the HDMI in while the PC is turned on, i get no sound. Always have to reboot.

Thinking back.... I think I had issues also, and my solution was to have a tuner between the TV and my computer (which gives me a hell of a lot better sound anyways) and passing the video through to the TV.

Done that guys. Still no joy.

see attachment. :)

Looking at your screenshot, it doesn't actually mention HDMI on the audio device you have selected, it looks like you might have the boards digital out selected and not the cards HDMI

See mine:

Could be you need to install the cards driver again to get the audio working / enable something in the cards settings

EDIT - Just noticed that the name of the device you have selected for Audio is the TV Model number, is it possible that the machine thinks the TV is the sound card rather than the speakers? If you look at mine, it shows that the sound device is the AMD Card, it doesnt mention my TV that is connected to it

I'm not sure where it got the name from, but its configurable anyway so don't think thats related. I've currently renamed it to HDMI anyway.

I've also asked the question to Palit (brand of nvidia card) and they've sent step by step pictures detailing the same setup as mine, so I think the way devices are listed etc is okay.

I've tried many reboots, and in certain orders to no avail. Also updated the mobo bios just in case, but again no joy.

One thing I have noticed though, is that the TV's hdmi channel is dimmed as if its not available - even though selecting brings up the picture. Its almost as if the TV has told the PC it can do sound, but the PC isnt telling the TV know sound is coming down the cable. The HDMI channel icon lights up again when using another machine (laptop, xbox, etc).

I had a quick look through the thread here but didn't notice if you had tried a different HDMI cable or not ?

EDIT - I see you tested that cable with another machine, still wouldn't hurt to try a new cable with this machine

Ok thats weird. I tried another cable, worked fine, went back to the original cable and now thats working, that makes no sense! I'm worried that it'll stop again, but for now its working! Many thanks to you guys.

Heh, strange, maybe just the whole removing and reinserting of the cable cleaned a contact on the cards port

Great news :)

    • As I've been usually saying lately - we all can thank "AI" for this.
    • Friday Windows 11 preview builds are here. Insiders in the Experimental (formerly Dev) and Beta Channel can download builds 26300.8697 and 26220.8690. My Windows11 device on the Preview Channel just got 26220.8728. My guess is this build is a nightly update from 26220.8690.
    • Traffic has a surprisingly unexpected impact on your surroundings by Sayan Sen Image by Radik 2707 via Pexels A collaborative study by researchers from several Israeli institutions found that everyday pollution from traffic and industrial activity measurably changed the atmospheric electric field over the Tel Aviv metropolitan area, providing new evidence of how human activity can influence the lower atmosphere. The research was led by Dr. Roy Yaniv of the Hebrew University of Jerusalem and the Gertner Institute at Sheba Medical Center, Dr. Assaf Hochman of the Fredy & Nadine Herrmann Institute of Earth Sciences at the Hebrew University, and Prof. Yoav Yair of Reichman University. The study also involved Itay Froomer, a student from Hadera High School and the Israeli Museum of Medicine and Science (Technoda), who carried out the work as part of the Ministry of Education's 5-unit physics research track. The researchers focused on the atmospheric electric field under fair-weather conditions. Even in the absence of storms, a weak electric field naturally exists between Earth's surface and the atmosphere. One of the main ways scientists measure this field is through the Potential Gradient (PG), which is the inverse of the vertical component of the electric field. PG is a key part of the global electric circuit, a planet-wide system of electrical currents maintained by thunderstorms and electrified clouds around the world. Scientists have long known that the atmospheric electric field can be influenced by factors ranging from large-scale atmospheric processes to local weather conditions such as dust, fog and clouds. Human-made pollution is also known to play a role, but understanding exactly how urban emissions affect the electric field close to the ground has remained an area of ongoing research. To investigate this relationship, the team analyzed measurements from a newly installed electric field mill, an instrument used to continuously monitor the strength of the atmospheric electric field. The instrument was installed at the Center for Technological Education (Roter House) in Holon and became operational in August 2024. It was funded by Israel's Ministry of Education and the Holon municipality. The electric field mill forms part of a broader monitoring network that includes nearby meteorological stations and air-quality monitoring sites. This allowed researchers to compare electric field measurements with detailed weather data and pollution records to better understand what was driving changes in the Potential Gradient. The study focused on two major urban pollutants: fine particulate matter (PM2.5) and nitrogen oxides (NOx), both commonly produced by vehicle traffic and industrial activity. PM2.5 refers to microscopic airborne particles small enough to remain suspended in the atmosphere for extended periods, while NOx is a group of gases released during fuel combustion. Researchers examined daily, weekly and seasonal patterns in the atmospheric electric field and compared them with changes in pollutant concentrations. Their analysis revealed a clear relationship between NOx levels and changes in the Potential Gradient, particularly during morning and evening rush hours when traffic emissions were at their highest. “What we observe is a direct physical link between emission peaks and electrical variability,” explained Dr. Roy Yaniv. “NOx reduces atmospheric conductivity very quickly, so the electric field responds almost instantaneously during traffic rush hours.” Atmospheric conductivity describes how easily electrical charges move through the air. According to the researchers, nitrogen oxides rapidly alter this conductivity, causing a near-immediate response in the electric field. PM2.5, however, was associated with a delayed response. The researchers attributed this difference to the particles' longer atmospheric residence time, meaning they remain in the atmosphere for longer periods, as well as their different microphysical interactions with surrounding air and atmospheric components. The study also identified a pronounced "weekend effect." In Israel, traffic volumes and some industrial activity decline significantly on Fridays and Saturdays. During these periods, concentrations of both NOx and PM2.5 dropped, and corresponding changes were observed in the atmospheric electric field. “The weekend signal demonstrates just how sensitive the electric field is to changes in human activity,” the researchers noted. “When emissions decline, the electrical environment adjusts at once, providing a high-resolution indicator of urban atmospheric conditions.” The findings showed that pollution levels can influence not only the chemical composition of the atmosphere but also its electrical properties. Researchers said the results strengthened the case for using atmospheric electricity as an additional tool for environmental monitoring, particularly in densely populated urban areas where anthropogenic, or human-caused, influences are most pronounced. The study also pointed to potential public health applications. By combining air-quality measurements with observations of atmospheric electricity, researchers said they could gain a more complete picture of how urban atmospheric conditions change over time. “Integrating air-quality data with electric-field measurements gives us a clearer picture of how the lower atmosphere evolves moment by moment,” the researchers added. “It’s a framework that can support both scientific insight and practical environmental decision-making.” Beyond the scientific findings, the project highlighted a collaboration between universities, public institutions and secondary education. Researchers said the work demonstrated how students could take part in real-world environmental research while contributing to studies of air quality, atmospheric processes and their potential effects on society.

    • We aren't even at the all-star game and Microsoft is talking about an update that will most likely be released during the World Series if not after. A lot can happen in the world between now and the 2026 World Series, including the 2026 FIFA Cup. Tell me about it again after the FIFA Cup is concluded. That should allow plenty of time to prepare for it.
    • Great, tell me when I have a "Bad Pool Caller" elsewhere not in Windoze.
