hi, I bought a Gateway MT3422 Laptop and I downgraded the system from vista to genuine Windows XP SP2. Everything works fine except for the audio. I installed KB888111 hotfix and the Sigmatel HD audio driver from Gateway, but it wont work, and in Device manager under the Sigmatel HD audio codec sign there is a yellow dot. No sound can be played.
My system:
Windows XP Professional SP2
nvidia c51gm chipset/AMD hammer FSB
nvidia nforce 430 south bridge(MCP51)
Sigmatel HD 92XX audio Codec
Thanks in advance for the help!
If any more information is needed, I am glad to provide.
