need critical 64bit help

I need help finding certain drivers for my 64bit Vista Ultimate.

1. The built in web cam
2. Bluetooth
3. Sigmatel integrated audio

Unfortunately, Sony's site is too lame to show the actual models of each. I have no idea what the make/model is for the webcam. For bluetooth, I know its Toshiba, nothing else. For integrated audio, Sigmatel.

Sony's site provides only 32 bit drivers. Simgatel sold its division to IDT, which has no driver download on its site either.

Also, a tricky one is getting MCE to work with my tv tuner. Tried TWO USB tv tuners (both work in 32bit). Hauppuage and Pinnacle. I get green screen on both in MCE, although actual tuner is detected otherwise. Anyone know a trick? According to hauppauge's support, they said this:

Note: Vista 64bit with MCE has a memory allocation problem. If you have more than 3 gigs of memory, you will get green screens or loss of signal inside MCE. Reduce the memory to fix the problem.

You have to reduce the memory to 3 gigs or less. At the moment there is no other way around. The problem is not Hauppauge’s but a bug in Vista 64bit. Microsoft is looking into the situation and rumor is that SP1 will fix the problem.

Thanks in advance.

My Specs:
Sony Vaio VGN-FZ190
Vista 64bit Ultimate
4GB Memory
Core 2 Duo 2.4GHz
TV Tuner (tried two): Hauppauge HVR-950 / Pinnacle HD Pro Stick

1. The built in web cam

see this topic:

2. Bluetooth

64bitdrivers.com:: Bluesoleil bluetooth drivers for x64

3. Sigmatel integrated audio

One of these:

64bitdrivers.com:: Sigmatel Audio Driver for Sony VAIO VGN-FZ290 x64
64bitdrivers.com:: Sigmatel AC97 audio driver 5.1 for Vista x64
64bitdrivers.com:: Sigmatel STAC 9200 series audio driver 6.1 for Vista

If you haven't already, install the October cumulative MC update. It claims to address some issues with MCE, but isn't specific enough about what exactly. I'd say though, since this memory allocation problem is with MCE, then give this a shot, and keep up with the monthly rollups of the MC fixes.

Download details: Cumulative Update for Media Center for Windows Vista for x64-based Systems (KB941229)

Chad,

The blurb that Hauppauge told you is correct, although there is still some question as to whether this is a Vista problem or an issue with Hauppauge's Vista64 drivers.

I was having the same green screen issues with my Hauppauge PVR-150 TV tuner card. I used MSConfig > Advanced settings to set the boot memory to 3.2GB (3277MB), sacrificing about 800MB that Vista now no longer sees. Now the card works fine. I will run this configuration until either Hauppauge releases an updated driver, or Vista SP1 is released.

Hope this helps.
