Windows 7: ATI HDMI Detection of Hardware issue

To enable movie viewing on 55" LCD TV

This is a pain in the rear for me but it is the only way to get the HDMI audio recognized as a valid option in Audio Playback devices. (Video always works but the audio is says not connected)

To get the HDMI Audio detected, I have to....
First - On my TV I have to select the HDMI channel that is connected to my PC
Second - I have to un-plug and plug-in the HDMI cable. (I can hear the Windows 7 found hardware sound)
Third - Now I can select HDMI as my default audio device (everything works great)


I usually have to repeat this process any time the PC or TV gets shut off. I am worried about wearing out the HDMI port by plugging and un[lugging so often. This can't possibly be the way it is supposed to work.

This is not an intermittant issue - it is a matter of the ATI HDMI detecting the audio connection and is very repeatable and consistant. All drivers ATI and VIA audio are the latest to date as of today.

Maybe it is the Plug&Play component - TV has to be on when turning on the PC or I have to manually force the detection process (as above)

Video = ATI 4550
MOBO = ASUS P7P55D-E LX

I have read many post on this issue and First of all yes the TV must be on at all times on the HDMI signal if you don't want the signal broken don't turn the tv off use you're power saving feature

Let windows turn the monitor off for you that way simple mouse movement will bring back the screen also you should be able to right click and disable onboard then enable the HDMI sound by right clicking

I might add using power saving feature is the only way to keep from breaking the HDMI connection also i don't advise any heibernation or sleep mode because that will just break the signal the best thing to do is let windows turn the monitor off but do not put your machine in sleep mode or any other power save featurn just treat your tv as a monitor

I find this the only and best way to work the ati cards and yes you keep unplugging and plugging the HDMI cable something is bound to go wrong eventually

What gets me is the video always works through the entire process, how the heck can they get the video to always work and leave it with a ridicules audio issue that really ruins the experience for a lot of people. The video works regardless of whether the TV or computer is on first or whether the HDMI input on the TV is selected. Also after the computer wakes from sleep, the HDMI video is fine

If I knew this was an ATI issue then I would run out and purchase another videocard rather than have to disable sleep and leave my TV on 24/7. It is too bad that ATI support is so difficult.

Thanks for the reply
