Sound only works with earphones.

Saturday, March 15th, 2014

A recent upgrade of windows 8 to 8.1 for whatever reason prevented sound through the speakers. However, it would work through my ear buds. I have a Dell E6520 and of course Dell did not have an audio driver for 8.1.  I tried the 8.0 driver but no change.

I played around with the diagnostics and troubleshooting tools but they did not find anything.

One interesting possibility came from trying to play the test tones with the audio device.

I received this nice little message:  

Failed to play test tone.

A quick check on the Net showed someone else ran into this situation.

The steps to correct this error (at least for my situation):

  1. Right click the taskbar’s speaker icon and select playback devices(if you don’t have it on the taskbar, use the Sound control panel).
  2. Select the Speakers /Headphones and click the properties button.
  3. Click the Advanced tab.
  4. Click the Restore Defaults.
  5. Click the Test button and you should have sound

A rather strange problem and I am surprised….well?…not really that an update would do this.



What does the Dell Power lights mean?

Saturday, August 25th, 2012

Recently, I was asked what the amber 4 light meant and I had a machine which was flashing the 1 and 3 light. These could be found in a service manual, but who keeps those let alone read them these days.

A quick check of the Dell site found a document on diagnostics.

The 4 light meant a system was in recovery mode after bios pulled a checksum error.  A quick correction eliminated this condition.

The flashing 1 and 3 light was a bad PSU. A service call was made for this particular machine.

Shall I keep a service manual now?  Probably not. If I do, then this problem will probably never happen again. 😉
