The sound from my Inspiron 5523 often does not work (although occasionally it does). It seems to work after boot-up but after I play a .wav file using Windows Media Player the sound stops working.
Right now, with the sound not working, I right-clicked on the speaker icon in the task tray, clicked Playback devices, right-clicked Speaker/Headphones (which is flagged as Default Device), and clicked Test. I got the following message:
"The device is being used by another application. Please close any application any devices that are playing audio to this device and then try again."
I'm not sure how to resolve this. Can you help?
Many thanks.
