I have had this Thinkpad P50 since January and it has been functioning perfectly however starting roughly 3 weeks ago the speakers have been stuck on permanent mute. The mute key on the keyboard is permanently lit and if pressed the windows sound display switches from mute to unmute however the key stays lit. Headphone used with the audio jack as well as usb work perfectly and sound plays from other speakers(television) when using an HDMI cable. It seems the only thing effected is the laptops speakers.
Things I have tried:
I have tried uninstalling and reinstalling the audio drivers twice.
I have switched the laptop off and on again mutiple times.
I am running Windows 10 which is up to date.
I have made sure the audio is set to play out of the laptops speakers.
I have run the playback diagnostics in order to try solve this to no avail.
Any help would be greatly appreciated.
Solved! Go to Solution.

First, is there a speaker icon on the right side of the taskbar. (You may need to click the up-arrow to see it.) See if the speaker is muted. Then, look in the control panel under sounds. Find the laptop speakers and make sure the playback level is not muted.

Have you had the system attached to any bluetooth audio device ? I find myself having issues similar to those described above after I disconnect from my BT Cambridge G5 speaker. I had to uninstall BT and Realtek Audio drivers and reinstall to get them working again, after that happened all the Lenovo integration and Dolby app stopped showing up or working, but at least I now have functionality.

The speaker itself could be bad

Have you tried booting from a live Linux distro (USB, CD, DVD, etc.) to see if the sound works under that?

I had the exact problem descibed (Win10/1709 muted via keyboard hdw. Orange LED on above keypad...) For me I found that if I turned on the function lock (FN+Esc), then toggled mute with FN+F1 (not the mute button over the keyboard), It muted the OS, but unmuted the hardware, turning off the orange LED. Then I left-clicked the volume icon in the tooltray and unmuted the OS by clicking the x next to the speaker icon, everything started working again. Not very intuitive...
