No Audio Through Displayport - Monitor Recognized As Generic PNP In Device Manager
Sep 14, 2015
I am running Windows 10 Pro 64-bit on a Lenovo T420 laptop and use the following two monitors in extended display mode:
1.) ASUS PA238Q connected via DisplayPort (Primary Display)
2.) Samsung Syncmaster 245BW connected via DVI (Secondary Display)
The display of the monitors works perfectly, it's just that when I start windows, the audio comes through my laptop speakers. Under "Playback devices", it lists the ASUS as "Not plugged in." If I either power-cycle my ASUS or disconnect and re-connect the displayport cable, the monitor is detected as plugged in under "playback devices" and the audio comes through the speakers attached to the ASUS monitor.
I have a Intel HD Graphic 3000 card and the Intel HD graphics app correctly recognized my monitors by their true model #. Device Manager has my laptop display (LCD 1600x900), SyncMaster 245B/245BW/245BPlus(Digital) and Generic PnP Monitor listed (instead of ASUS PA238Q). There do not seem to be any drivers for the ASUS monitors off their site that I could find.
I recently got a new monitor, an Eizo EV2750, which Windows only recognizes as a generic PnP monitor.
I've tried connecting it thorugh DisplayPort, HDMI and DVI without any luck. The often mentioned sollution, to unlplug everything and wait 10 minutes, does not work either.
The graphics card seems to read the EDID however, as in nVidia control panel it displays correctly as EV2750. Same thing with other applications, like DisplayCAL which I use as my color management system.
Seems like it's only an issue with Windows. This issue, however, also means that I can't get full functionality from the monitor. For instance, the ambient light sensor does not work (which is typical when Windows doesn't recognize the display properly).
I'm using a Surface Pro 2. After my upgrade from Windows 8.1 to Windows 10, I'm not getting any audio out from the DisplayPort. I use DisplayPort to HDMI to a receiver. I've upgraded to the latest RealTek audio drivers, but it's not working. Could there be a different driver issue at play?
Laptop Samsung NP300V5A. Sound stops working about a month after Win 10 upgrade. No changes done at the time.Audio devices show up under Device Manager, but not under Playback/Recording Devices. Same for Realtek Sound Manager - it doesn't see the devices. I can install, delete and update drivers under Device manager but it doesn't make any difference. It is not a physical problem, tested on Linux live CD.
Solutions tried: -Installing various versions of HD Realtek Drivers (including windows update version) -Installing/Removing Realtek software. -Enabling/Disabling devices under Device Manager -Called spirits of ancestors. Seemed like it worked for a while, but ended up being a joke. -Did system restore to various dates. -Restarted in safe mode -Restarted various services such as Windows Audio, Windows Audio Endpoint Builder, Plug'n'Pray, Power, etc. -Checked system, application and driver even logs. -Tried a couple of registry fixes. Angered spirits of ancestors. Turning gray.. -Reinstalled chipset drivers -Rebooted about 30 times -Sound Device Troubleshooting finds no issues -Display Disabled Devices is enabled
My computer currently has 3 monitors connected to it. 2 through the graphics card (R9 280), 1 through the integrated graphics (AMD HD 3000). Not sure when why or how, but the integrated graphics card can never pick up what type of monitor is connected to it... so it always gives me a bunch of generic 4:3 resolutions...
I've tried uninstalling the drivers and letting them reinstall. I've tried swapping around the cables to see if i could get lucky with one of the other screens, but they all face the same issues. I've tried buying brand new cables across the board because sometimes people say that's the issue. But not success.
The cloest thing i have is apparently a custom resolution setter, but it was created for windows 7 in mind and doesn't seem to work on windows 10 (PowerStrip).
My question is, is there anyway to format the list so i can select the correct resolution? It's a Toshiba TV/Monitor and it seems like every thing else attached to my pc (even 3rd party programs i tried to use to forcably change the resolution) can spot it and hand me back the correct resolution but i can't seem to change it. I get Genertic pnp through the control panel (the only place the monitor shows up in) and even then the correct driver doesn't show, it's the Microsoft Generic driver.
Mobo: MSI AMD 3000 series, cant find exact model.
I've updated my AMD drivers to the latest and so far can only modify the resolution to stock ones that look horrid on the screen. Any program in windows 10 to change the resolution of a screen.
The generic PnP monitor driver in the device manager keeps reenabling/reinstalling itself whenever I restart Windows 10 on my early 2011 MBP (Boot Camp). I want to leave it disabled so the brightness controls on the keyboard work, otherwise they don't.
I do not want to disable automatic driver update checking by Windows 10. I know that if I turn off automatic driver installation via device installation settings and enabling "Prevent installation of other devices not described by other policy settings" will keep the "Generic PnP Monitor" driver uninstalled, and this is certainly one solution that works, but disabling these features interferes with the installation of other devices (one example is the TAP driver for the Private Internet Access Windows client).
There is no available apple display driver I can install over the generic driver that I have found, but the brightness controls work perfectly when the Generic PnP driver is disabled/uninstalled. I just wish it'd stay that way after a restart.
I just upgraded to Windows 10; not much problems for me, except one that I really wish I new that before upgrading. Let me just say this; the Windows 10 app on my pc (running Win7 Ultimate) did not say anything about this issue, that's why I upgraded.
Under my windows 7 I had 2 Realtek RTL8168D PCI-E Gigabit Nic; which I had setup for teaming with the Realtek Teaming Utility; after the upgrade I found out that utility was not compatible with Windows 10, which sucks.
My real problem is under the Device Manager I only see one (1) Nic listed.... is this normal for Windows 10?
Also, how to setup a NIC Team without using the Realtek utility?
i have my ASUS X555LD for almost a year now, so as far as date is concerned my laptop shouldn't be too old to suffer such illness. So it came with Win8.1 x64 of course and just recently, as soon as Windows 10 was released, i upgraded quickly.
but right after i upgraded to Windows 10, my laptop became ill and had this errors:
1. i got BSoD Most of the Time, one would say CRITICAL_PROCESS_DIED or UNEXPECTED_STORE_EXCEPTION. there are times my laptop would freeze in the BSoD, not even the 0% would move to 100%. so i had no other choice but to force shutdown it, and sometimes after turning my laptop on again i end up at my BIOS with no HDD nor BOOT ENTRY listed. as i experimented, i had to press slightly hard on the right side of my Laptop where my HDD is Located just for my Laptop to re-read my HDD once again, as soon as i got back to Windows 10, i ran an HDD Check and nothing was wrong, no bad sectors or anything. this is confusing me as to how it is happening. so i somehow got used to BSoD since my Laptop frequently experience it. sometimes just a simple movement that would shake my laptop would turn into BSoD again, i suspect something like my HDD or loose or the likes. i dont really know.
2. after the BSoD Case, a week or three i guess. i started to loose Audio Ability. it was just this morning, the Volume Icon has a "RED X" on its icon and states "No Audio Output Device is installed.". and after checking my Device Manager, to my surprise the Built-in Audio Device (Realtek) is not there. i don't know how or why it happened but i can't get it back.
even checking the sound tab on the control panel doesn't bring out Audio Devices.
i was wondering if ASUS or the PC Store where i bought my Laptop would fix it for me as per warranty is involved ?
I connected an audio cable to my laptop but when windows asked what the cable was i accidentally checked the box that said microphone. Now i can't change it anymore and my audio device is in the recording tab instead of the playback tab. How do i change this?
I plugged in my USB drive and I get notification USB device not recognized. In This PC it shows but it looks like this:When I right click to try and format it, nothing happens. I also tried renaming the drive letter, nothing. I tried many USB fix tools, such as, USB drive defender, Flobo, mUSB Fixer, USB Refresh, USBFix 2016, and most of them didn't even see the device in the list. It's SanDisk Cruzer 16GB.
Just upgraded from Windows 7 to windows 10 --all working well except continually get message " USB DEVICE NOT RECOGNIZED ,the last USB device you connected to this computer malfunctioned and windows does not recognize it "I have gone into Device manager and see the yellow icon next to "unknown usb device (device descriptor request failed ) I have tried deleting it, disabling it , updating the drivers and still get this stupid error message. Which USB caused the problem . No usb presently connected. I will not update other 2 computers to 10 if I cannot get this resolved. Was not a problem with Windows 7
My Targus amu73ap mouse that was workinG perfectly with 8.1 is not working on either my PC or Asus T100 hybrid after the update to windows 10. I keep getting a message saying that the usb device malfunctioned.
Tonight, I tried to look at my mouse properties in Device Manager. I wasn't able to do anything, because for some reason my Device Manager is refreshing every second. I can't click on anything and I don't know how to stop it from doing this.
I have googled this all over the place and there are all sorts of issues with DVD / CD-ROM players no longer being recognized but I haven't come across the same problem I'm having.
I upgraded to Windows 10 64bit from Windows 7 64bit. One day while I was transferring data from my SSD boot drive to my HDD storage drive everything locked up, I got an error message (that I didn't save) and all of a sudden my HDD was no longer visible in My Computer. I ran into all sorts of issues following this and believed that something had corrupted during the data transfer so I opted to disconnect my HDD and do a fresh install of windows with a format on my SSD.
Everything was working well until one day the same thing happened with my DVD/CR-ROM drive, it just disappeared from My Computer. I went to install / check for updated drivers in Device Manager and I believe I clicked uninstall by mistake.
Now when I look at Device Manager there is not even a DVD/CD-ROM option (menu spot for it).
Above: So here you can see My Computer, there is my SSD Boot drive but the DVD / CD-ROM is not there
Above: The DVD / CD-ROM drive does not show up in Disk Management, I've tried rescanning drives, refresh, nothing. (As an aside, what are those unnamed disks???)
Above: Device Manger, there is not even an option to view DVD / CD-ROM drives.
Above: Regedit - A fix I saw was to check this registry for UpperFilters and LowerFilters both of which were not there so I didn't touch anything here.
So far I have done the following troubleshooting:
Turned off the PC and unplugged the CD/DVD drive from the Sata Port. Restarted the PC and loaded windows. Shut off the PC again and re-connected the CD/DVD drive.
When I started the PC back up I entered BIOS and the drive shows up under Sata Port 2 like it should:
ASUS DVD RAM GH75N
There is power to the drive, it opens and closes and if I put a disk in it spins up.
So this leads me to believe the drive is ok and the cable / port are good as it's being recognized.
I think my biggest concern is not being able to see a menu in Device Manager for DVD/CD-ROM drives. I'm not sure how it got removed or how to get it back.
I'm going to try and contact ASUS to see if they have specific drivers for this drive meant for Windows 10.
Upgrade from win 7 pro 64 to 10 pro 64. All hardware and software was new, name brand and authorized at time of original build. The bios shows the drive as sata 3. I checked the windows advisor and the drive is rated as acceptable. It's an Asus sata dvd-+rw.I used every windows repair and diagnostic tool I could find to no avail. The only update for the dvd player was firmware which I installed. I tried switching the bios to auto play but it did nothing.
I did have problems with the upgrade. I could not get the upgrade icon although I had all the required files and had auto upgrades set, so I downloaded 10 to a dvd and did the upgrade. That's the last time the dvd player was recognized. It is working. Asus loads a mini os on it's mother boards called Speed Gate. I can use Speed Gate to to read file on a dvd but it wont execute.I tried making a recovery usb but it fails. I then tried reset but it disconnects the key board and mouse so I have to do a hard restart so reset fails too. I tried restarting with the win 10 dvd in the drive but it wasn't recognized. To update the bios the instructions say use the install disc. I tried using Speed Gate but could only see the list of files. It does give the option of using the asus update utility which should be in programs (apps in 10) but it isn't there.
When I updated my computer from windows 7 to windows 10, all of a sudden I don't seem to have a CD/DVD drive anymore. It shows up in the BIOS but not on the actual computer. I have tried to make sure the computers all plugged in correctly and it is. So what can I do to resolve this issue, and if there are so many problems with windows 10 why on earth allow have of the entire population download, especially when MICROSOFT should have thought of all the bugs and fixed them ahead of time. Its not fair to offer free upgrades, when its essentially a downgrade?
I have recently installed window's 10 and have only recently discovered a program called realtek HD Audio manager. I would like to have separate audio through speakers and headphones, but the realtek only allows me to hear audio through one audio source. is there a way to separate the two so i can have audio (music etc) and have Skype run through my headphones. this problem only occurred after installing windows 10.
