Dears,
since 6 months I noticed a really annoying issue. When I connect my W540 to HDMI to a TV or a projector, the audio doesn't work.
I have to uninstall and reinstall audio drivers, but as soon as I make an hot HDMI plug (through ultra dock station or miniDP connector), sounds disappears and I had to swear to get it back. if it gets back, because with the projector it will never come back.
I use a really long HDMI cable (> 5m, but this should' t be an issue).
Tried to update K21000 driver to the last version NVIDIA Optimus Display Driver for Windows 8.1 (64-bit), 8 (64-bit) - ThinkPad - US
Tried to unplug the W540 battery.
I am quite desperate and unable to resolve this issue !!!
Tried all options here but NONE working https://support.microsoft.com/id-id/help/4520288/windows-10-fix-sound-problems
Sound comes after each reboot. After the 2nd HDMI hot plug sounds disappear. That's weird and crazy !
Tried to reduce the screen resolution
I hope somebody can help me in resolving definitively this issue.
I read several post but none provide an effective solution.
I am bored an frustrated.
