Just got my computer back from Dell tech support having sent it because of an issue with no audio output device installed and the red x on the toolbar. The computer is in the exact same state as before I sent it with nothing fixed. I've tried reinstalling the drivers multiple times, checked if audio services were running and all of that. Feels like a huge waste of money at this point and is especially disappointing because this computer was actually a gift for someone. Has anyone had this issue with this computer and have it resolved without resorting to an external usb sound driver?
You can diagnose this by performing a system recovery (reset the laptop back to the original factory configuration.) If there is still no audio immediately after recovery, before getting on the internet, then the audio hardware has failed and Dell will have to fix it under the terms of the warranty. In other words they could not say it is a software issue and therefore not covered.
If the recovery does fix it, but the problems recurs after getting on the internet, then probably some Windows Updates-related issue.
