Hi,

 

Did the sound stop working when you tried to update the driver or did it happen suddenly out of the blue? Code 45 seems to be that the device is not connected to the motherboard or it's broken. My guess: it's hardware problem unless it happened because of an attempt to install a new driver. Seems that you bought the laptop recently so my advice is to send it to repair for free if it's still under warranty and if that's not possible let me know and tell me why it's not possible.

 

Cheers,

Luís

You mean you lose sound only after you suspend the laptop and if you reboot it's ok or was it a permanent sound loss even if you reboot?

Code 10 is another story. Seems to me you don't have much knowledge about it so I recommend you take the easiest path which is uninstalling the sound card drivers, if you don't mind losing the IDT control panel and stuff. In device manager just uninstall sound card driver and check the box saying to remove software too. As you have been installing drivers there may be some older ones that windows will reinstall automatically so keep uninstalling sound card driver (don't forget to check the box) until windows install its default driver which is called something like "High Definition Audio Device".
