    No not that i know of i havent updated or done anything to my computer since i bought it...only certain programs allow the sound to work while most others there is no sound at all. I just dont know what else to do

    So i updated it and they said it was updated to the most recent software and there were no warnings i just dont understand why it does this.

    Check under device manager and see if there is a 'warning' for your audio. I would recommend updating the audio drivers as well. Acer's website should have links for this. Let me know if this helps/fixes.

    Have you updated or loaded any applications between the time it worked and did not?

Sound


The red light is because its a digital/ analog output. Its known as s/pdif..Sony/Philips Digital Interconnect Format- also known as TOSLINK or lightpipe.

http://en.wikipedia.org/wiki/Spdif

it sounds like you may need to reset the nvram / pram on your computer. If this doesnt not work, then you may need to reinstall the os. it's known as an archive and install. Have you recently done any upgrades or installs? Do you write music and may be using an external sound card? you may want to go to system preferences, choose sound, and make sure the onboard ins and outs are being utilized. but the fact that youre not getting the proper on screen icon representing the sound level would indicate and issue with the hardware engaging with the software.

Before you attempt the archive and install, I would make sure you have the most recent version of your OS....


Keep me posted...
