Audio works through the HDMI to external screen. When I unplug the HDMI the speaker icon says there is no audio device installed. Can't seems to figure out what is preventing local speakers. When I look at playback devices, only external screen shows up. It's ENVY dv6 running Window 8.

Hi gb1768,
I see that you are having audio issues after the recent Windows Update.  There are a few troubleshooting steps you can try below to resolve the issue and after that if you are still have no luck then there is a walkaround for the Windows Update.
The first thing to try is this HP support document No Sound from Speakers. It has a number of good troubleshooting steps including using the built-in Windows troubleshooter.
Another solution is to uninstall the driver manually then force Windows to reinstall it. Follow the steps below to do that.
Step 1: Open Device Manager and open Sound, video and game controller section.
Step 2: Right click on your audio driver and select Uninstall.
Step 3: Restart the computer. Windows will then force in the driver on startup.
The last troubleshooting step is to try creating a new user account to see if the issue is only affecting the one account. This can happen is something has been corrupted in the one user profile. This HP support document Managing User Accounts and Logins look under the section Creating a new account in Windows 8.
Here is the workaround for the Windows Update:
At this point, unless you want to reinstall the operating system, the only other option is to tackle the update, KB2962407.
Uninstalling the Windows Update, then hiding it, is the only method of eliminating the issue if it caused by this update. Here is the procedure for uninstalling the update:
Step 1. Go into Control Panel, then click on “Programs and Features”.
Step 2. Click on “View Installed Updates”. Look for the update with the ID number KB2962407.
Step 3. Right-click on the update and select “Uninstall”. Restart the computer.
Next, here is the procedure for hiding the update:
Step 1. Go into Control Panel, then click on “Windows Updates”.
Step 2. Click on “Check for Updates”. When the process is completed, is should find important update(s) available. Clicking on the message will open a window where the important update(s) is.
Step 3. Right-click on the KB2962407 update and select “Hide Update”. This will prevent the update from being installed next time Windows Updates are being installed.
