Would have a slew of drivers after the install from chipset to audio to other drivers.
This is usually rough on folk but I don't see the make and model so you'll have to detail every driver you installed for me to comment further.
Hi everyone.
Please i urgently need your help.
I formated my windows 7 computer and reinstall windows 7.
Now when i connect the system to a television via hdmi cable, i get no audio from the tv. The audio still comes from the laptop.
When i go to manage audio device in the control panel, I see only the laptop speaker. There is no tv or external speaker (even though I have checked both the show disabled devices and show disconnected devices options.)
Checked my drivers, and windows tells me but the High definition audio hdmi and high definition audio controller are up to date.
( I have just one high definition audio controller driver under systems in the driver window. I am letting this know because i saw two in a picture posted online)
Have tries my laptop with three televisions (that work well with my friend’s laptop).
I really need urgent help. I will be very grateful for any help i can get. Thank you guys in advance.
