Hello,
I hav win 7 and my laptop is hp dv 6701Au.
My audio is not working and there is a red cross on the audio sign on the lower rt hand bottom corner.When I take the cursor on this sign it says "no audio output device is installed"
When I open device manager and thn go to audio,video and games controller option-->properties it shows "Currently, this hardware device is not connected to the computer. (Code 45)"
How do I fix this....Pls help.....

Go to control panel-sound

Right click on the playback tab

Select ''show disabled devices '' option

Does it display your speaker? if yes right click on it and enable it

This is not a driver problem ,this error code usually related to hardware issue.
When did this problem started?
Try this

Unplug power,battery ,push the power button for a minute insert battery and power again.Go to BIOS and set to to defaults and see if sound card is getting detected.
