W540 HDMI output ISSUE

2019-12-14, 11:19 AM

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 https://support.lenovo.com/us/en/downloads/ds037793

Tried to unplug the W540 battery.

 

Sound comes after each reboot. After the 2nd HDMI hot plug sounds dissaper. Tht's weird and crazy !

 

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.

Dear community, 

right today nobody helped me. I am not able to understand if my W540 is suffering an hardware error or a software one.

I must restart PC anytime which is annoying

The issue looks like the one described here
