Hi guys.
I'm here because I've heard a lot about the experts in windowssh blog so I decided to ask my problem here. I have a HP ENVY 15t-j000 laptop running the latest windows 10 edition which is 1607. Since I've upgraded to anniversary update I have a lot of problems and many errors in the event viewer but above all my biggest problem is with my DVB-T dongle which stopped working suddenly. I was using the dongle before anniversary update with no problem but after the update it started to malfunction. First, for a few times when I started up my system and plugged the dongle into usb port I saw the error on totalmedia software which said no hardware detected. For about 5 or 6 times I could resolve the issue by closing the software, unplugging the dongle, plugging again and opening the software. With this simple approach I could use the DVB-T dongle but suddenly one day it didn't treat the same way and the issue wasn't resolved. I've done a lot of things like uninstalling and installing the driver or opening another user account and some other stuff to resolve the issue but no luck. I have a lot of errors in event viewer and I don't know if they are related to this problem or not. I remember some changes to the system before this problem occurs but I don't know which was exactly before this problem so I mention all of them. In the period of 15 days before this problem I've done these things:
- updating bios driver manually by downloading the latest driver for my system from the HP
- uninstalling and installing some different drivers for the sound a lot of times (because I had problem with IDT High definition codec driver and I couldn't switch between sound outputs in windows 10 and the sound was a little distorted, so I was struggling with the sound driver and finally I chose the windows generic driver though I can't still switch between sound outputs and the speaker volume is too low but at least I have clear sound through my headphone)
- performing some windows updates however I must mention that one of the updates didn't downloaded and was stuck in downloading so I downloaded it from microsoft update catalog and installed manually. ( I haven't updated my windows to the KB3194496 yet)
- updating some drivers of different devices through device manager
If I want to give you more details about my problem I can say that I've tested some softwares for DVB-T like Dvbviewer and Sichbopvr. These softwares shows that they have detected the device and I can see the name of my device but when I want to scan for channels it shows me the error of "No hardware, No device detected or the device is being used by another software". It's very strange that they see my device but can not use it or access it. The problem is not with the device because I can use it on my android tablet without any problem. I've also tried sfc/ scannow and dism and clean boot but non of them resolved my issue. So if anyone can help me to resolve the issue I will be very grateful.
Thanks for your support.
