IDT audio says HDMI is unplugged

I cant get it back to plugged in when the cable is connected. The video transfers fine to the external monitor but I cant select the option to make the HDMI audio default audio device in the IDT control panel.

I tried plugging and unplugging it with no luck. The only way to fix it as I can tell is to uninstall the HDMI audio driver from Catalyst and reinstall. I did not have any issue when I had the 4870 X fire system.

What am I missing here?

Thanks AWHW

 

I experienced the same and here's what worked for me.

1. Make sure the laptop is running on power and not on battery
2. Connect the HDMI cable to the laptop and the external source.
3. With it connected to both sources, restart the laptop.

After following those steps, the HDMI audio was selected and if I plugged it in or out it would recognize that it was plugged in or not. It works now but the very first time I made the connection, I followed those steps.

 

Thank You

What I seems to be messing it up is using FN-F7 or FN-F6 instead of using created profiles in catalyst. I'm not sure about this but I think thats whats causing it for me. When I used these keys after posting the sound started to work. I will investigate more on this later.

Another problem is that Windows sounds are delayed or just not working at all on the external display.

 

Can't seem to pinpoint it yet.

 

what fixed it for me is installing this driver for hdmi :

1. go to this link
2. Click V on I Accept the above
3. Download ATI HDMI Audio Device
4. uninstall your current HDMI driver from device manager including the V on remove driver from machine
5. Install the downloaded version
6. Reboot

Your HDMI connection will work every time.

 

Ok. My first suggestion stopped working for me.

Here's what I did and is working for me now.

1. I went into device manager > Sounds, video, and game controllers, Ati high definition audio device

2. Right clicked on it and select "uninstall"

3. Selected "delete the driver software for this device" and pressed ok

4. Went back to the device manager, right clicked on "sound, video, and game controllers" and selected "scan for hardware changes". It found the device and I asked it to search for drivers for it. It installed a microsoft driver for the audio.

5. With the older microsoft driver, it's working every time.

Microsoft
7/13/2009
6.1.7600.16385
Microsoft Windows

The old driver that didn't work for me always was

ATI Technologies Inc
11/13/2009
7.11.0.7700
Microsoft Windows Hardware Compatibility Publisher

 

weird, for me the microsoft driver didn't work.

 

hy,

I don't know if i have to open a new tread or if i can ask about my problem here since it's almost the same, the only difference is that it works fine and for no obvious reasons it stopped working and says HDMI is unplugged, if I reboot it's ok it works fine and again after a while it stopped working.

I tried to do what you explain here but :

- first i don't understand what you mean by "including the V on remove driver from machine", what is the V ?
- i can't install those driver, i got an error msg, saying there is no driver on my computer who can handle those driver

 

V = checkmark

 

oki thanks, but I still don't get it. the only option i got is uninstall/disabled/update, i don't see nothing who need to be "checkmark"

 

Once you click uninstall it should offer you to also delta the driver from your system. That option is selected with a checkmark (V)

 

thanks to your help and sorry i'am not that blond usually , i totally missed this V

- well i did what you said, i reboot cause he asked me to, but on boot windows automactilly install drivers without asking me anything..
still I tried to install the driver you gave but i got this error msg



- then i tried other stuff, i uninstalled the ATI audio driver without reboot and i still got an error msg trying to install those drivers, msg was different, it says "no drivers are handle in this driver suit"



- then i uninstalled it again/reboot, except now i didn't have ATI audio driver anymore, only audio driver from microsoft



i'am kinda lost

 

hy,


is there any others audio driver i could possibly try ? could my problem be hardware ?

this is a bit annoying this sound issue and so randomly, during 2 days it was ok and now it start again to malfunctionn, for ex, i run a video and sound doesn't appear immédiatly, i have to wait 1 or 2 minutes him to show up even after a reboot
