Windows 7 no sound

I have a Dell Inspiron 1420 and just installed windows 7 ultimate and now my internal speakers do not work. I can get external speakers to work. Any suggestions?

Hello,

Have you got the latest drivers installed? Download and install it here:

http://support.dell.com/support/downloads/download.aspx?c=us&l=en&s=gen&releaseid=R171786&SystemID=INS_PNT_PM_1420&servicetag=&os=WLH&osl=en&deviceid=8907&devlib=0&typecnt=0&vercnt=3&catid=-1&impid=-1&formatcnt=1&libid=3&typeid=-1&dateid=-1&formatid=-1&fileid=235779

Also make sure that the audio jack is properly plugged in.

When I run that I get a error here is the report.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:





When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
