About two years ago I built up a desktop computer. Running an AMD Phenom II x6 1035 processor with 8 mb RAM. Video card is a Radeon HD 6450, connected via HDMI to a high def monitor with internal speakers. Using Windows 7 Home Premium and run IE 10.0.10 at this time. Rarely open any other software other than Office 2010 (word and excel) Been running just fine until...
Two or three months back a red x appeared over the speaker icon in my sys tray. No audio. Not a big deal, I mostly read e-mail but do like to watch a youtube video on occasion. From the beginning, when I looked at the device manager, the Video output showed AMD Radeon HD 6450 and the Sound showed AMD High Def Audio Device. Now the sound manager also shows Realtek High Def Audio. The audio error check shows speakers not plugged in. If I restart the computer, Audio works fine through the HDMI cable for an hour or so, but if I let it go to sleep the dreaded red x comes back.
My first thought was a bad HDMI cable, but A. it works fine after a restart and B. I've tried two other cables with the same result (and they both work fine with the tv and surround sound). When I allow the system to suggest a fix, it shows how to plug a speaker set into the colored speaker jacks, doesn't recognize the HDMI output at all. I'd prefer not to buy a set of speakers and have another cable running (plus desk space for speakers I don't need).
I'm thinking that I have a device conflict between the AMD Audio and the Realtek. When I disable the Realtek driver and restart, i'm fine for a while but then when the machine goes to sleep the Realtek driver comes back and i'm back to no sound. I've not tried uninstalling the Realtek driver, but i'm wondering if that's not the answer? I've not added any software, though i'm certain there have been some Windows updates.
By the way, when the audio is working I can watch youtube router videos. When the sound is not working, the videos will not play (I still have a full hi def monitor, but the youtube video goes to a black screen)
I'm guessing a conflict between Realtek and AMD Audio devices, but can't figure what is triggering it. Can I dump the Realtek device? Again, I hate the thought of buying a separate monitor cable and speaker wires--but i'd sure like to be able to click a youtube link on Router Forums without having to restart (and by then I forget what I was going to watch!!)
Any ideas?? Thanks!!!
