Turned my inspiron on this morning and there was no sound at all.
speaker symbol on the toolbar says no output device installed.
checked the power service was running.
updated the bios to a4.
tried to update the audio driver, received an error saying that it was not compatible with the installed hardware.
dxdiag came up blank, nothing shows up in device manager.
It's got me stumped, far as i can tell it's like the sound card has died.
Thanks in advance
Fixed! instead of trying to install the audio driver manually i gave windows troubleshooting menu (troubleshoot audio playback) a whirl and i don't know what it did differently but it managed to get the driver installed.
Thanks for your help.
Hello Corry. Is this the driver you tried to install and got the error message?
IDT R308434, A01 126.96.36.19941 (dated 8/9/2012)
If that driver will not install try running the Dell Diagnostics audio tests to check for hardware failure.

Jim, yes that is the driver that i tried to install.
Ran the diagnostic test no error message no test sounds or any mention of sound in the logs after the PSA test completed.
So the Dell Diagnostics tests did not come up after the PSA tests? I know that Dell no longer includes the Dell Diagnostics in the N5110 but I was hoping that the N5050 still has it. The Dell Diagnostics audio tests are the only easy to use tests that can distinguish between a software versus a hardware audio problem. The other way is to return the laptop to the original factory configuration which involves backing up data etc, . If that does not solve a problem that did not exist when the laptop was fresh out of the box, then the cause is hardware failure.
You can try running the audio tests in Dell's PCCheckup, but those tests require an audio driver so it probably won't work, but I'd give it a try anyway.
About the driver not being able to install, you don't actually need the IDT driver because if all IDT driver files are missing from the hard drive then Windows is forced to install its own native driver. You can try to do this by going to your hard drive c:\dell\drivers\Rxxxxxx Expand all folders and subfolders there. Delete all folders that have a subfolder named "WDM". Those will be the audio driver folders and it is safe to delete them. Next, reboot and normally Windows would install the native driver. If you still get the error then that is another indication of hardware failure.
The only other things I can think of to suggest are to use System Restore to return to an earlier configuration, or Factory Image Restore to return to the original configuration. Sometimes a Windows update can so thoroughly trash a system that only doing this fixes it.
