lewmur Posted November 19, 2013 Share Posted November 19, 2013 I just built a new box with Win 8.1 and using HDMI to connect to a large screen monitor. When I first boot the system, every thing works fine and I have sound in all the apps. But, on an intermittent basis, is lose the audio from the HDMI and the red blip appears on the volume control icon. When I click on it, it says that no speakers are connected. The only way I've found to get the audio back is to reboot the system. Any ideas? Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted November 19, 2013 Share Posted November 19, 2013 Are your speakers built into the large HDMI monitor? Quote Link to comment Share on other sites More sharing options...
lewmur Posted November 19, 2013 Author Share Posted November 19, 2013 Are your speakers built into the large HDMI monitor? Yes and the audio is received via the HDMI cable. Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted November 19, 2013 Share Posted November 19, 2013 Have you tried a new HDMI cable? Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted November 19, 2013 Share Posted November 19, 2013 Also have you tried using an eraser or Q-Tip w/alcohol, or De-Oxit (formerly known as Cramolin) to clean the cable? Amazon and other places have De-Oxit. Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted November 19, 2013 Share Posted November 19, 2013 I hope it's not the monitor's connector or the traces where the connector connects to main board of the monitor. Quote Link to comment Share on other sites More sharing options...
crp Posted November 20, 2013 Share Posted November 20, 2013 (edited) I hope it's not the monitor's connector [...] I had that happen to me, with the same symptoms of the OP.OP have you tried a different HDMI port on the monitor?

lewmur Posted November 20, 2013 Author Share Posted November 20, 2013 (edited) I hope it's not the monitor's connector or the traces where the connector connects to main board of the monitor. I use the same cable and HDMI port on other devices with no problems at all. If the connectors weren't making contact, then re-booting wouldn't clear the problem. If just a momentary loss of contact is causing the problem, then it is still a software problem. Win8 shouldn't require a reboot just because of a momentary loss of connection. edit: I found out a couple more things. I can cause the problem by switching modes on the monitor. IOW, if I switch from HDMI to PC and then back to HDMI, I no longer have sound. Second, I can get the sound back by logging off and back in. Much quicker than a full reboot but still a pain.

goretsky Posted November 20, 2013 Share Posted November 20, 2013 Hello, I am not very familiar with HDMI audio output, but am wondering if the audio device might be getting powered down to save electricity, and the drivers that support it are unable to restore it to a functioning state (initialize, assign it a memory address, etc.) when the system resume full power operation. Is there some sort of option in the properties for the sound device that allows the computer to turn off power to it to save energy while sleeping? If so, does disabling that option make any difference? Regards, Aryeh Goretsky Quote Link to comment Share on other sites More sharing options...

And if Win8 isn't capable of recovering from a "power saving" condition with something as basic as HDMI audio, then something is very wrong.

raymac46 Posted November 20, 2013 Share Posted November 20, 2013 (edited) I assume you have installed the latest drivers for your video card along with the HD audio drivers? Edited November 20, 2013 by raymac46 Quote Link to comment Share on other sites More sharing options...
lewmur Posted November 20, 2013 Author Share Posted November 20, 2013 I assume you have installed the latest drivers for your video card along with the HD audio drivers? I installed the ones provided by AMD and all of the updates provided by MS. There is no "video card" per se. The MB uses the video generated by the AMD Series A APU.

raymac46 Posted November 20, 2013 Share Posted November 20, 2013 I have an A8-5600K but the machine it's in runs Linux only - and I don't connect with HDMI. So that won't help. I did read somewhere that earlier versions of the Catalyst software may have had some HDMI audio issues, so if you upgrade to the latest version from AMD's website that may be useful. 1 Quote Link to comment Share on other sites More sharing options...

goretsky Posted November 21, 2013 Share Posted November 21, 2013 Hello, Under recent versions of Windows, e.g., Vista and later, even desktop computers have power management of their subsystems turned on; this is done to ensure that even desktop computers running Windows consume less electricity when idle, in order to reduce electricity bills. If it is, in fact, a power management issue (bear in mind, this is just a guess on my part), the issue is not with the Microsoft Windows operating system, per se, but with either the firmware in the motherboard or video card, the device drivers involved in managing HDMI audio, or some combination of the two.

Regards, Aryeh Goretsky I didn't say desktops didn't have power management. I said that it wasn't invoke. IOW, all setting are set to "never". But even if the setting were causing the problem, they shouldn't. If they do, it isn't a feature, it is a BUG!!!!!! Quote Link to comment Share on other sites More sharing options...
