Hi Greg,
I want to thank you for taking the time to respond to my issue.
- I tried all of the steps in all of the nine links that you sent me and below are the outcomes of my various tests.
- I tried plugging the headset into a different USB port (on my docking station instead of my laptop), however the same issue occurred — I still see the message 'No audio device is installed' when I go to the Volume mixer it shows me a 'Detecting problems' window which attempts to solve the problem with the headset but is consistently unsuccessful. Here is a video showing what happens when I click on the speaker icon in the system tray: https://www.dropbox.com/s/b6f3ooljn2vvbtv/Headset-detecting-probems.mp4?dl=0
- I confirmed the headset is set to 'Enabled' and are set up as the default device.
- I updated the driver again using the option to 'Search automatically for updated driver software' and I still get the message that reads: 'The best drivers for your device are already installed'.
- I tried disabling and then re-enabling the device, however the issue still remains.
- I tried to click the 'Rollback driver' button but it was unavailable (greyed out) — probably because I reset my laptop yesterday so there is no previous driver to roll back to.
- I tried the suggestion of checking the manufacturer's website for the latest driver, but the Microsoft website says "Additional software, firmware, or drivers are no longer available because Windows 10 has all the necessary software to support Microsoft LifeChat headsets".
- I tried to play around with the 'Default format' setting of the headset (2 channel, 24 bit etc). I can see the 'Advanced' tab when I access the headset from the 'Recording' tab in Sound > Recording > Properties > Advanced, but I cannot see an 'Advanced' tab when I access the headset in the 'Playback' tab.
- I did not need to change any settings related to a front 3.5mm jack, Bluetooth or wireless connectivity since this is a USB headset.
- I went to the Sound tab in Settings and tried to move the volume slider off zero, but it will not allow me to — it just keeps jumping back to zero. And when I click on 'Troubleshoot', it inevitably takes me back to the familiar 'Detecting problems' cycle (see video here: https://www.dropbox.com/s/bce7nsa79amj25e/Headset_Volume-slider.mp4?dl=0)
- I did not need to check the audio settings in my apps as the problem is occurring universally in Windows, not just in one particular app.
- I tried to disable audio enhancements for the headset, but when I click the Properties button on the Playback tab, I do not see an Enhancements tab — I can only see a General tab and a Levels tab.
- In Search, I typed 'find and fix audio' but this did not bring up anything. I think this troubleshooting tip was written for a previous version of Windows perhaps?
- I do not need to restore my computer as I did a full reset yesterday and there are no previous drivers to roll back to as my laptop came installed with Windows 10 Pro
- I confirmed that the headset is not muted.
- I have tested the recording function of the headset and it works correctly. Therefore, this has isolated the problem to just the Playback function of the headset.
- I tried disabling my audio driver (Realtek Audio) in Device Manager and then reconnecting the headset. However, this made my PC spontaneously restart, and after this the microphone input of the headset also stopped working. But when I clicked on Troubleshoot, this fixed the microphone issue, but the playback still doesn’t work.
- I uninstalled the audio driver (RealTek Audio) again from Device Manager and this time restarted my computer deliberately. When the PC restarted, it reinstalled the audio driver as expected. However, when I plugged in the headset again, the same issue still prevailed.
- I ran command prompt as an administrator and typed the specified commands given in this link. I'm not sure exactly what the purpose of this was as there was no explanation provided in the link, but it did not fix the issue.
- I followed your steps regarding the AutoPlay settings, but I cannot see the headset in the list of autoplay devices.
- I followed your steps to open the sound settings. I ensured that the headset was selected for both Playback and Recording default devices. I then clicked the Troubleshoot button for both. For the Playback device, this took me through the same 'Detecting problems' cycle as in my video above. For the Recording device, this showed two issues of which one was fixed and was not, but Recording was working nonetheless.
- Regarding your suggestion to roll back the device driver, please refer to my comments at 1(e) above. Regarding your suggestion to uninstall the device driver and restart the PC, I did this. It prompted me to restart the computer from the dialog window, but instead I clicked 'Cancel' and chose to follow your instructions to restart using the keyboard method that you described. This worked!! When my computer restarted, it miraculously allowed me to move the volume off zero for the headset and allowed me to use the headset as a playback device.
So thank you very much, and I hope this can help someone else too!
Solution:
- Go to the Device Manager (Click Start and type Device, then select Device Manager)
- Click on 'Sound, video and game controllers' to expand it
- Double-click on 'Microsoft LifeChat LX-3000'
- Click on the 'Driver' tab
- Click on 'Uninstall device'.
- A window will appear that reads: 'Warning: You are about to uninstall this device from your system' and gives you two buttons: 'Uninstall' and 'Cancel'. Select 'Uninstall'.
- A window will appear that reads: 'To finish removing this device, you must restart your computer. Do you want to restart your computer now?' Instead of clicking 'Yes', click 'No'. (I don't know if this specifically makes a difference, but I'm just sharing what I did that worked for me because I followed Greg's advice to the letter).
- Press Ctrl+Alt+Delete on your keyboard.
- On the blue screen that appears, press the Tab key repeatedly until you reach the Power Icon in the bottom right.
- Press Enter on your keyboard.
- Press the down arrow on your keyboard until you reach the Restart option.
- Press Enter. This will restart your PC and automatically reinstall the driver for the headset.
Note - I'm not sure if any of the prior steps that I took actually contributed to this solution (particularly the command prompt which I have no idea what that was for!)
