This morning I installed contextant high definition audio HD automatically through Windows Update, and now I have no sound..
I've been tying to fix this all day, I've uninstalled it, rollover to the one I had before, nothing. Installed it again, disabled all sound controllers, restarted and enabled them and still nothing.
I cant hear anything, except for very low hissing, but once my computer beeped so I know the speakers are still attached.. It says they are there and working, although somewhere it said they were not present.. Confusing.
P.s Its a toshiba p105 and run on Vista always have.
Can you help me?

A HDMI cable can output both audio and video, whilst some computer with Windows XP cannot automatically switch to HD Audio output as Windows 7 can. Thus manual setup can solve the problem.
After connecting the HDMI cable, Go to "Start" > "Control Panel" > "Sounds and Audio Devices", double-click "Sounds and Audio Devices. Select "Audio" tab on "Sounds and Audio Devices Properties" window.
On "Sound playback", change "Default device" from "Conexant HD Audio output" to "NVDIA High Definition Audio".
Your television should have several HDMI ports, select the appropriate HDMI port number and check if TV is not muted.
If you have not run Windows Update, this is the place to start. Go to Start - Programs - Windows Update at the top of the menu. It will detect any updates required or optional for your PC. It will also check for any hardware updates that are available for your system. You should select to install of the hardware updates and see if there is an update listed for your sound card. It will be obvious if there is one. If not, let me know and we will go get this from a different angle.
Ok-This is what you are going to do: Right click on My Computer icon-scroll down to manage-click-device manager-click-find sound controller/sound card-right click-update, let it do update. That is about best thing in Windows 7. Reboot and have fun. Good luck!
