Hey guys, Here are my computer specs i5 760 evga p55 ftw corsair 450W 8gb of corsair ram ati 4890 Just recently I purchased a cheap Vivo 40" Tv from DSE for my xbox and PC gaming. I had issues originally with this setup through the HDMI where the montior would keep dropping out as if losing signal and regaining signal. I used a different HDMI cable which seemed to fix this issue. Now with the new cable I am sometimes coming back to my PC and noticing that the sound through the HDMI/4890 says it is unplugged. The video is still going through the HDMI as I can see but the sound will not working until I unplugged and re-plug in. Even after disabling and renabling in playback devices. Any ideas on how to fix this? EDIT: I haven't noticed it EVER dropping out when I am actually using the PC, only when I come back from not using it for a while (I don't turn this computer off)> Thanks, Micky.

Is TV switched off in between use? Is computer going in to any low power mode? I have similar issue. Now is fixed by following this procedure. Ensure TV is fully awake/on prior to waking computer from sleep/hibernate/screen saver. Essentially if computer "wakes" or whatever, and doesn't "find" the screen already fully on it doesn't activate audio signal even though it eventually activates the video signal.

I have the same problem with my receiver which takes audio and visual from the PC and outputs visuals to the TV and audio to the speakers. For me, turning the receiver off and on again fixes it. Maybe try turning the TV off and on, or change channels and back to that HDMI source.

Yeah same issue for me on a 4850. Only does it when coming out of sleep if I have the receiver turned off. I usually give it a minute then I right click on the little speaker icon on the taskbar and re-enable the hdmi out on the video card as the default playback device and it fixes it. That is on Windows 7 btw.

Yeah I haven't had any luck with the above posters ideas. It still doesn't seem to want to work. I will try yours this afternoon. I have bought a HDMI switch so that I can switch between the TV and my computer monitor so in the worst case scenario that your idea doesn't work I will have a workaround.

TBH I don't feel very confident, as it is coming up as unplugged in the playback menu. Maybe when changing it to default it attempts to bring it up again. Who knows.

Yeah the option for making it the default is greyed out because it has detected it as being unplugged.

As I stated in the first post, I originally had a display issue that was fixed by changing HDMI cables to a new one. I did a test that I ran throughout the day where I used the original cable (the one with the shitty display) and it did not drop the audio. So I have put and order for a new 1.4 HDMI cable that I think will fix the issue. I am currently it in a workaround configuration until I can test this more. It looks like it might just be two dodgy ebay cables that is the culprit.

Thanks,

Micky.

You did suggest that it was only happening when you were away from your PC; maybe disable all of the sleep options in the power configuration for a few days and see if it goes away then too.
