ATI Radeon 4670 And AMP

[VinFanatic]

I have an ATI Radeon graphics card (4670) the one with the build in HDMI audio connection. When I first got it, I spend weeks trying to get the HD audio sound and I finaly got it. I used:

Ati HDMI audio driver (not the Realtek ones) Realtek 97 for my recording devices. Catalyst control center 9.1 and the HDMI audio driver fixed all other problems. Sony amp DDW 7000 (detected in catalyst as sonyamp).

Does anyone have their HDMI audio working after upgrading to 9.3 or 9.4 with the built-in driver?

It had been working fine for me until I did the upgrade. Now, it says the HDMI audio device is installed and working, but there are no playback devices installed. Opening the volume mixer says the same thing "No playback devices installed". There is also a red X over the speaker in the task bar.

In addition, Catalyst does not detect the amp if I do this.

Any ideas? Please help...

because it may also possible that ATI cards may not be compatible with your system specification.
