[NAME]  - Have you confirmed the speakers/headphones are plugged into the audio output jack on rear of PC? Can you test a different audio output device on this PC or test this output device on another PC to rule it out as the problem? Did you check all the Windows audio output settings to make sure the correct output device is selected, and did you configure Waves MaxxAudio correctly, as I posted earlier in this thread? Note: You have to set the volume correctly, both in the Windows audio settings and at the bottom of the Playback screen in Waves MaxxAudio, too. All of that needs to be done for audio output.  If you click the sound test button at bottom of the Waves Playback screen do you hear anything from your external speakers/headphones? Also, open Device Manager and click View>Show hidden devices. Then expand all entries in DM and look for anything marked with a ! or named "Unknown". If any is marked with !, look to see what error message is shown in the Device Status box on the General tab when you open that entry in DM.  If you see an "Unknown", right click and uninstall it. Then click Action>Scan for hardware changes and see if anything new gets added to the list in DM. Then reboot and test audio again, making sure all your Windows and Waves settings are correct.
I have a new 7790 all in one.  There is a single audio out jack on back but when no sound from external speakers when plugged in.  I can see audio output happening in Maxx audio app and volume mixer, but no sound.  Unplugging and then there is sound from the speakers built in to monitor.    At first, external speakers worked but then stopped.  They were old anyway so bought new ones but now no sound at all through this jack.  Maxx confirms external speakers vs internal speakers in the app but no go.  Any ideas?
Audio output not working or intermittant on 7790 AIO??
