1. Reboot the system and try the audio again.
2. Check the volume control, including the "mute" button
3. Try a different set of speakers or headphones
4. Try a different audio file or disc
5. If you just installed some software or hardware and the audio stopped working after that, try to install the chipset driver for your motherboard, reboot, then install the audio driver. Reboot then try the audio again.

Color coding

The colors of the jacks on the rear of a system are:

• Green - Line Out (speakers or headphones)
• Blue - Line In
• Pink - Microphone in

Things to watch out for:

• Try to understand the question that is being asked by the audio interface. If you plug speakers into a rear audio port, make sure you understand the jack sensing message that pops up. If it is asking what source to send that jack, make sure you choose the correct source. We have seen where customers select "rear" and then get no sound because, in this case, the rear means the rear content from a 5.1 source, which if not playing a 5.1 movie would be no sound at all. The right answer would be front - which is the front signal in a 5.1 setup.
• HD audio by design can do two things simultaneously. In one case we saw, the customer was trying to get headphones to work on the front audio jack. Headphones would work on the rear jack but not the front. This customer also had an HDMI monitor with audio. At this point, the customer was using up both audio functions - HDMI and rear panel. In order for the customer to get the front port to work, the HDMI digital audio had to be turned off.
• Some of the audio enhancements such as Karaoke or environmental effects, if turned on, may stay in the on state through a reboot of the system, which you wouldn't expect. Some things like this can make hearing spoken voice harder to understand, or in some cases, eliminate the voice altogether.
