Hi John, thanks for the reply and for the welcome. Yes, I completely removed the sound driver after the SP1 install. In fact I did this after I noted the problem.
After the complete audio driver remove I reboot Vista and, in the new boot, the default Vista HD audio drivers were installed. This didnīt solve the problem. With default Vista audio driver I got the exact same problem: no sound on Windows apps the seems to address the sound requests by calling Vista procs.
Applications that seems to access directly the sound drivers works OK. I can list GOM Player (
GOM software - Free, Simple, Light, It just plays! - GOM Media Player, GOM encoder) and AIMP2 (
AIMP2: Home Page) as apps that sounds (literally) OK.
After this I reinstalled my mobo audio drivers (which claims to inlcude Microsoft UAA Driver), downloading the latest version from Gigabyte site. I see that Realtek drivers sucessfully replaced the default Vista HD audio driver, but without solving the problem.
Itīs very weird the fact that some apps can reproduce sound and others (Vista audio effects and web browsers, IE and Firefox included) can not...
