How does this help?
Shouldn't the "AMD High definition audio device" show up in device manager and under sound in ctrl pnl?
I Flashed the 4550 with Sapphire BIOS and now it does not work properly. Tried to flash it back to Dell BIOS and it says my Dell BIOS file is bad. I have an Identical Dell card to get the BIOS off of again though. Have not had time to try it yet.
I tried the second card - no audio device on it either.
I tried turning off onboard sound. No audio devices detected at all.
I put the card in my main rig (to flash it back to dell bios) as a second card and only the amd audio device from the main 4870 shows up.
Attached is a screencap of Device Manager, Audio Devices and GPUz. Please comment if something looks wierd.
There is a audio device listed in what you posted for the HD4550. That being the case, if you are connected, via HDMI, to a monitor/display with speakers, it should produce sound. Make sure the volume is turned up on the moitor/display.
The reason I tried flashing the 4550's BIOS is I suspect Dell disabled the audio on the card to eliminate confusion for business users.
I flashed the card to ASUS and Sapphire 512MB 4550s and the card works funny with the Sapphire BIOS and not at all with the ASUS Bios.
I could not get far enough into windows to see if the audio device showed up with the Sapphire bios.
Had to flash it back to Dell to get it to work properly.
The Card does not Have an HDMI Port and did not ship with an HDMI adapter.
I wonder if the audio device is not present on the card or is permanently disabled.
