    You don't have to uninstall Dolby for EqualizerAPO, just disable it. Take a look at the sticky thread in order to install EqualizerAPO. It can work without or with Dolby enabled.

    I've did the instructions on the "Sound Modification/Volume Increase" section but it didn't work. I went on game and it turned off Dolby Audio.

    I use the exact same method and it works for me. Make sure you follow the directions carefully and read the whole post.

    I followed exactly what the section said and carefully did what it said. Although at the end when I changed the Preamp to +3 the volume got louder which means it work's perfectly, but the concern is that when I launch CS:GO it turns off Dolby Audio. I disabled Xbox Gamebar and disabled "Let these apps use microphone" via Windows Settings. Any more help?

    Also, I'm planning to get the Acer Triton 700, but before I get it I want to know if it has the same problem like this.

    Dolby is getting disabled when you open games that use your microphone. To fix Dolby not getting disabled again, be sure to install EqualizerAPO both for Speakers and Microphone. It should not get disabled anymore after that. Also the problem is not only with games that use microphone, this also happens with Skype, TeamSpeak or any other VoIP software or ANYTHING that uses your mic.

    To everyone using my fix or trying to use it, i have some news. Tested out a few scenarios and seems that Windows 10 build 1703 breaks my audio fix (Windows 10 Creators update). If you have Game Mode (Game Bar, Game DVR) in your settings section, it means you have the 1703 build Creators update and EqualizerAPO will not work anymore with Dolby. I suggest people with the Creators update to try out the Premium SRS driver until i figure out how to make EqualizerAPO work on Windows 10 Creators update! Thanks!

    So i've been looking for a fix for this F.... dolby digital plus turning off by itself for a very long time and i just stumbled across this post and it was simply a god sent gift.
    The only problem i was facing was infact dolby digital plus disappearing after i installed equalizer APO on windows 10.
    The solution i found to this was the following: I downloaded dolby digital plus home theater separately and installed it, however it was giving me an error that the driver and dolby versions were mismatching.
    After some digging i found this post: https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/dolby-digital-plus-audio-driver-is-7649-and/98a71242-2f0b-469c-8a80-0a09cd5c032c
    Where basically this guy modded the dolby digital plus dll so it would work even if the driver and the program version mismatched.
    So now i have windows 10 with latest drivers + equalizer APO + dolby digital plus home theater separated from the driver and working by itself. I also installed Peace (which is an equalizer APO extension to basically give it a nice GUI) and boosted my basses  =) 

    TL:DR : - Install latest realtek drivers, 
                - install equalizer APO (dolby digital plus panel will be gone), 
                - download realtek driver from this page (https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Uninstalled-Dolby-digital-Plus-7-5-1-1-Lenovo-y50-70/td-p/2054523) and at the last installation step choose not to install so the program will only extract the files that contain dolby digital plus
                - Install dolby digital plus home theater 
                - download and copy the dll the guy modded from this link                                              (https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/dolby-digital-plus-audio-driver-is-7649-and/98a71242-2f0b-469c-8a80-0a09cd5c032c 
                - start dolby digital plus
                - Dolby digital plus wont turn off by itself
                - ?????
                - Profit

    PS: just reporting what worked for me, feel free to modify the post or remove the links if they're not allowed.

    If any of you guys are having trouble installing Equalizer APO and it having no effects, make sure you do the Troubleshoot thing and Install as SFX/EFX (experimental). Been trying to reinstall drivers for hours with no results until I checked that.

    One thing to note. I just did this Equalizer APO thing and it seemed to work great with PUBG.  I then tried COD WWII and was getting about 7 FPS in multiplayer only, stand alone worked fine (75+ FPS).  Uninstalled APO (or disabled it) and COD WWI multiplayer works fine now, smooth as butter.

    Hi I am a new proud owner of helios 300, I am an audiophile as well apart from being a gamer, I usually l connect the helios  to external 2.1 or 5.1 speaker for music listening. I thought Dolby Audio enhancement supposedly to be good so I left them turned on. I found that my speaker 10mm teeter produces buzzing found at certain part of music(possible certain sound frequency). I thought my speaker has spoiled and sent for checkup, when the technician play songs from their phone with spotify the buzzing sound was not heard. They told me it's possibly source problem(low quality mp3) and denied warranty claim.

    So I went back and play my FLAC and other loseless audio, same buzzing sound was heard. Hence I went and play around with the audio driver setting and I just disable the Dolby audio, of cause suddenly the default sound volume became less, so I had to turn up the volume bar in windows and also on my speaker system, to bring back the volume normally produced with Dolby Audio on. To my surprise, the buzzing sound was all gone, not heard even the volume was maxxed out. I think Dolby Audio amplifies certain frequency until overboarded volume and causes the sound breakoff.

    2nd surprise! The music actually sound nicer without the "Smart" enhancement by Dolby. So my advice is turn off the Dolby and tune up the volume by yourself using EQ . It only causes more problem than helps.  Just my 2 cents :)

    Hello fellow users,
    I have a Predator Helios 300 with a severe audio problem. As others have mentioned, it makes loud crackling and static noises. Also there is a terrible lag when I'm watching videos. People speak long before their mouth ever moves; it's worse than those old dubbed karate movies that we used to laugh about. It's virtually impossible to watch a video without having to read subtitles (which usually aren't available). I read that I should replace the Realtek driver with the standard Windows 10 driver and it actually worked - for about a week. I didn't notice Windows updating and when I checked my drivers, it's still using the Win10 driver. I don't know what changed but it gradually got worse and worse and after about a week, I'm back to where I started. I am REALLY irritated that I bought this laptop and it had such problems right out of the box. So much for tech support. I'm not very well-versed about audio workarounds but I can follow directions for the layman. Hey, I'm an old lady so if you can spell out a fix for me, I can probably (hopefully) do it. I don't have speakers hooked up to it, just a regular headset alternating with stereo Bedphones. Also it's doing what someone else has mentioned: I originally could listen to a video with it set at about 30-35 and now I'm up to 80 on the volume and it's still not very loud. I can see NVIDIA Virtual Audio Device (Wave Extensible WDM) listed under the Sound in Device Manager but I'm not sure if I need to make changes to that or not. Sorry, I'm a bit confused by the process and just so frustrated with this laptop. It's been severely disappointing in more ways than one. I won't even get into the topic of overheating -- grrrrrr. If you can help me, THANKS!!!
