Dolby Sound Driver

[Nayra Waddles]

Theaudio is handled by the laptop by Intel Display Audio (Intel HD Graphics 4600) over the HDMI cable. When I go and configure the Intel Display Audio connection under Sound, I get a choice of stereo, 2.1, 3.1, 5.1, 7.1 speakers. I select 5.1, and start the audio test. Here's where the problem is--I can only hear tones from the front left and front right speakers. The test routine shows that it is trying to send a tone out to the other speakers, but I can't hear anything.

Switching to my DirecTV service using the Monoprice switch, I get full 5.1 sound. Running a self test on the Panlong decoder shows that all speakers are working properly. But for some reason Windows will not play 5.1. The laptop is properly detecting that the speakers are attached, because I can switch the Monoprice to 2 channel mode and my only speaker selection in Windows shows stereo only. Switch back to 5.1 on the Monoprice, and Win 10 reports that the surround speakers are there. Still only the front left and right speakers work.

The vexing thing is that this USED TO WORK!!! I noticed, about a week ago when I was encoding a documentary, that I couldn't hear the dialogue, only the ambient noises. I thought I encoded the show improperly because the documentary was originally in French with english as an afterthought, so I did it again. No change.

I've tried rolling back drivers, going back to the Manufacturer's web site. I've tried older Intel drivers, as well as the newest release. I've unstalled the device and deleted the drivers and then let Windows Redetect and install new drivers. Nothing seems to work

We always recommend to install the drivers provided by the manufacturer of the laptop, on the following link you will find the drivers for the Satellite S55t-A5237 for Windows 10, not sure if that is the specific model of your laptop, but if it is you can try to install the IDT Audio driver and DTS Sound / DTS Studio Sound:

As far as I can tell, there have been no new software updates, although Microsoft may have run a Windows Update on me while I was not paying attention. I don't recall adding any new software that might have compromised the audio systems.

In addition, I removed and then reinstalled both the IDT driver and the latest Intel driver that you listed in your response. There was no change in behavior. I've attached a few images showing where this seems to be happening. In the second image, when testing the configuration, only L and R "speak". All of the other channels remain mute, even though the test sequence seems to be trying to send a signal to them.

MooseFlunky: I just received some updates from the research we are doing on this matter. And just to let you know, our Debug team has been unable to reproduce this issue using a A/V Receiver: YAMAHA RX-V663. They were able to play sound with 5.1 Surround with no problems at all.

It seems that as long as the HDMI can direct play (without having to go through the operating system) the audio channels, everything works perfectly. However, any time the windows drivers get involved in handling audio, I only get two channels.

So, after installing 4279, rebooting the system, and then trying to reconfigure the sound, I still only have FR and FL audio on the 5.1 setting. See the image above, dated March 12th, to show what I'm talking about.

MooseFlunky: I just received an update on this matter, based on that information by testing an older driver we can confirm if this problem is actually a regression bug or not. Since the problem persists after that, then it looks like a compatibility issue with the Monoprice, and in this case the best thing to do will be to get in contact with the manufacturer of the Monoprice to report this scenario.

The drivers are all up to date, but windows seems to think the device is stereo only. On the box, which I still have, it says it supports up to 7.1 surround sound, and including 5.1, but nothing I can find in the catalyst control center or Windows 10 seems to have any settings to enable 5.1. Among other issues, it also states that it supports audio over minidisplay port, which it wont do for some reason. The cables I purchase advertised audio too, but windows pops up a message any time I use them saying "display port does not support audio, you will need a separate audio cable". Mostly I just use the HDMI port anyway, but my key issue is that I want my 5.1 surround sound but cant seem to enable it anywhere in the 5 or so windows audio settings menus or the catalyst control center.

In my case, I have one HDMI cable from my GPU card connected to my Onkyo A/V Receiver and made "default Audio Device" and then I have another HDMI cable from my second GPU card output HDMI to my TV. Thus I have both 5.1 sound while the TV and Monitor are on. But the TV & Monitor speakers don't work since I have the A/V Receiver as default.

Unfortunately, you can only have one "Default Audio Device". You may want to connect directly to the PS4 or Xbox, whichever has the 5.1 audio, directly from the GPU card and make it the "Default Audio Device". If the PS4 or Xbox has video output, then connect it to the TV.

Before I got my DP Monitor and had a previous HDMI Monitor, I had my HDMI cable connected directly from my GPU card to my Onkyo Receiver input (making it my default audio device in Sound panel). Then from my Onkyo Receiver HDMI Output I had an HDMI cable connected to my Monitor. Then I had a second HDMI cable connected from my GPU Card to my TV. The only sound I had was from my Onkyo Receiver while still getting Video to my monitor and/or TV.

When you click on "Configure" it will show all the different audio setups you can use on your Audio Device. All starts at "Stereo" by default. So you must manually set it at 5.1 each time your update your AMD Audio Driver.

If you have your 5.1 Audio Device connected to the AMD GPU, then AMD will provide the Audio drivers. If it connected to the motherboard, then the Motherboard's Audio driver are the one powering your 5.1 audio.

My Onkyo is listed as HT-R380 in Sound Panel and is powered by Nvidia HD Audio since I have a Nvidia GPU. But when I had a HD7850 it was the same except it stated it was powered by AMD HD Audio driver.

elstaci, I already found that menu after rummaging around through google but it only gives me the option for stereo. Sounds like my drivers are out of date then. I imagine the latest available drivers for my card, if not the drivers that came with it out of the box should have the 5.1 audio drivers.

Either that or the video card is pulling the TV's info through the HDMI (apparently some video cards can do that?) and reports to windows that the speakers are stereo, despite the TV's outputting my PS4 and Xbox One through the optical with surround. Seems Nvidia's video cards tend to lock audio options based on the HMDI port info reporting at least.

I'm using the audio from the HDMI or displayport coming from the video card itself. Apparently unplugging the HDMI lets it send audio through the displayport, a bit irritating that it doesn't just let me choose.

Trying to check for updates through catalyst control center seems to open up Microsoft edge, who decides to hijack the page and inform me that "You should be using Microsoft Edge Browser!" and refuses to let me reach the appropriate page.

Assuming it's not a driver issue or something after all, I don't suppose there is a sensible reason that I have no option to tell it to output in 5.1 or 7.1 anyway? I mean, my PS4 and Xbox One clearly can output in 5.1 audio over their respective HDMI ports on the same TV the PC is plugged into, and the TV sends that HDMI audio out by it's optical to my 5.1 audio system just fine. Even my PS3 and 360 can output 5.1 over the HDMI. ARC and optical have been around for a while now, so it makes no sense to me that a video card that cost as much as those machines couldn't. Optical in particular was out long before my video card was released, it seems like a disservice to forcibly limit the audio output based on the monitor or TV's internal speaker when output options are usually a standard feature.

After everyone's input, it seems the solution is to order an entirely new sound system. I hoped to avoid it since my Pioneer HTS-GS1 is perfectly up to the task if not for what I consider to be questionable decision making somewhere in my video card's design process. I hope they will accept this as constructive criticism when I say My Xbox One, PS4, 360, PS3, PS2, and even my gamecube/wii have some sort of 5.1 audio output options over this surround sound speaker when routed through my TV. If the issue truly is by design and not a driver issue, I fail to see how this benefits the customer, and consider it a huge oversight that no override option is available.
