Tips Low dialog volume with DTS movies on RealTek compared to AC3

A simple trick to fix the low dialog volumes of a DTS audio track played with a Realtek is to use the Loudness Equalization.

Click to Read More

I am using Home Media Player Classic x64 v1.9.8 (24-10-2020) to play movies on my Windows 10.  My Motherboard is a Z270 Gaming Pro Carbon with a Realtek® ALC1220 Codec.

When playing movies with a DTS audio track, the volume is always really low compared to movies with an AC3 audio track, especially regarding the dialogs.

It was not the case when I initially installed Windows so I presume that this is a regression due to some driver updates... But a simple trick was to enable the Loudness Equalization via the Realtek HD Audio Manager.

If you don't know how to open the Realtek HD Audio Manager, open it directly from Windows Explorer or with Win+R: C:\Program Files\Realtek\Audio\HDA\RtkNGUI64.exe

Tips Easy replacement or upgrade of HTC Vive Headset's lenses

I did scratch the lenses of my HTC Vive Pro while keeping my glasses to play. I couldn't find original replacements lenses but realize that I could simply use the lenses of my Samsung GearVR instead. And the result is amazing !

Click to Read More

As you know if you googled for information about the lenses of the HTC Vive, those are "Fresnel lenses". I.e.: a set of flat surfaces with different angles. Many people suffers of "God Ray" artifacts with those lenses. I personally found indeed the visual experience as quite poor for such a high-end headset.

The good news is that it's very easy to replace those lenses. And it can be done:

  1. Not only with cheap 3D printed adaptors to reuse the lenses of a old Samsung GearVR.
  2. But also with prescription lenses adapted to your eyes if required.

First, a lot of information can be found on Google with the keywords : HTC Vive GearVR lens Mod.

If you need prescription lenses, simple google for HTC Vive prescription lenses. There are plenty of serious sites and they provide both the lenses and the adaptors:

If you want to reuse the lenses of an old Samsung GearVR:

  • You need to print your own adaptors. Plans can be found on Thingiverse. Ex.: here or here.
  • Or you can buy them on internet. There are plenty on eBay (with or without lenses). Search for HTC Vive Mod Upgrade Kit
  • The adapters are the same for the HTC Vive, HTC Vive Pro and HTC Cosmos also.
  • The Samsung GearVR lenses MAY NOT BE those from the 2015 version (the white model). Those are smaller. You need a dark blue version of 2016 or 2017!

There are many How-to on the web, such as this video which is quite complete for HTC Vive or this one for HTC Cosmos.

Notice next that opposite to what is illustrated on some video, I had no need to unscrew anything to pop out the lenses. Neither on the GearVR, nor on the HTC Vive.

The result is really fairly dramatic!

Tips VMWare Workstation not compatible with Windows 10

Starting a VM this morning, I got a new message "VMware Workstation and Device/Credential Guard are not compatible". To be able to run my VM, I had to disable this Credential Guard.

Click to Read More

Credential Guard uses virtualization to store credentials in protected containers separate from the OS. As a result, the information Credential Guard protects is safe even if malware or some other malicious attack penetrates an organization's network.

But it prevents VMWare to run VM's.

To disable it, copy this script in a file named "disableCG.ps1" in your personal home folder C:\Users\<Your Name>\

Run next a PowerShell as Administrator:

Pay Attention that this will reboot automatically your PC !!

In this PowerShell, execute: cd ~

Next execute : .\disableCG.ps1 -Disable -AutoReboot

You will see errors displayed in Red in the PowerShell. This won't be a problem. And after a minute, the PC will reboot.

During the reboot, you will be prompted to confirm that you really want to disable the Windows Defender Credential Guard. Press the Windows Key or F3 to confirm.

 

Other options : https://windowsreport.com/disable-credential-guard-windows-10/

Ex. Execute in a PowerShell run as Administrator: bcdedit /set hypervisorlaunchtype off

 

I also had to remove "Guarded Host" and "Hyper -V" via the Control Panel > Programs > Turn Windows features on or off

But now, Docker does not run anymore on my PC as it needs Hyper-V :(

Tips Use HDMI output of Lenovo ideapad Yoga 500 to get Dual Screen

When I connected for the first time my Lenovo Yoga on my TV, using a HDMI cable, I couldn't extend my Desktop to this second screen, using the F10 key. The solution was to do via the Intel Graphics Settings.

Click to Read More

  • Right Click on the Desktop to access its Display menu:

  • Click on the button "Detect":

  • Once the second screen has been detected, click either on "Clone Displays" or "Extended Desktop" and then Click "Yes" to apply the change:

 

Notice: I also had an issue with the HDMI port. I think this issue results from the pulling force exerted the each time one opens or closes it (the hdmi port is really next the lid). The "contacts" of the port are faulty (Loose contacts). As a solution, I had to push up the cable lightly up to force a good contact.

Tips Cannot use inventory in Vivecraft

My daughter suddenly couldn't use the inventory anymore in Vivecraft, once opened. She couldn't pick or move items in there. The cause was that Vivecraft's window was not active on the PC at that moment.

Click to Read More

Vivecraft is a mod that turns Minecraft into an exceptional VR experience. Concretely, I use it to run the game from SteamVR and play with it using my HTC Vive pro setup (Be sure to setup and run the game as explained here. Launching the game from the VR Room or Steam does not work).

When my daughter experienced her issue with the inventory, I was working on the PC at the same time. Vivecraft works indeed fine if someone else is using the PC, as long as you don't need the mouse to interact with the game. And this is the case  when you want to use the inventory or use some menus.

Concretely, on the screenshot here under, the cursor + will only appear if, on the PC, the window of the game is activated. I.e.: if you clicked on it with the mouse or used Alt-Tab to give it the focus.

So, each time my daughter want to use the inventory, I temporarily give the focus to the window of ViveCraft by switching to it with Alt -Tab. I can next continue to work...

Tips Fix SD card or Memory of external devices not visible

Recently, I plugged on my PC various devices having an internal SD card or an internal Memory. And although I could hear the typical sound made by Windows when a device is plugged in, no new Drive appeared in Windows Explorer. The problem was with a Mounted Network Share using the same letter as the one assigned by Windows to the new Drive.

Click to Read More

Looking into the "Device Manager" console, I didn't see any devices not recognized as illustrated here under. So, the device was correctly recognized and its drivers correctly installed.

I tried different USB cables and different USB ports (both 2.0 and 3.0), but without success either.

Finally, I opened the "Computer Management" Console and looked into the "Disk Management" part. There I saw a Drive greyed out. I noticed that it was assigned with a letter which was actually used by a Mounted Network Drive. I did simply right click on it to "change Drive letter" with another one and it appeared magically into the Windows Explorer. 

To be complete, I have to mention that the conflicting Mounted Network Drive was not available and all letters between C: and the one used for the Mounted Network Drive where in use . This was maybe the actual root cause of Windows assigning the same letter to a new USB Drive.

Et voilà.

Tips How to change the langage of the "Samsung Account" webpage

When I visit my account on the website of Samsung, it is always displayed in Dutch (used in Brussels, my location) instead of French (my language).

Setting the language "French (European)" in my profile is not fixing this issue. The solution is to change the language on this membership page.

Tips Get audio via AV port and video via HDMI on a Yamaha HTR-4067

I have connected the DVI output of my PC on a HDMI input of my Yamaha HTR-4067 but was missing the sound. I solved that issue by connecting the S/PDIF output of my sound card on an AV port the Yamaha and "combining" both HDMI and AV.

Click to Read More

Theoretically, one should be able to have music via the DVI port of a PC by using an adequate DVI to HDMI adapter (19 pins). But my problem is that my internal sound card is dead and I am using an external one. The easiest for me was therefore:

  1. to connect that external sound card directly on the AV1 port of the Yamaha, using an optical cable.
  2. to select on the Yamaha Remote the HDMI input to be displayed
  3. to click on "Option" on the Yamaha Remote to configure the "Audio Input"
  4. and select "AV1" as "Audio Input"

Notice that one can select a different "Audio Input" for each HDMI input.
