Running a new installation of Windows 7 32 bit on an AMD780G board.  I had been running the beta for several months, and for the most part it worked perfectly.  Now, when I resume from sleep, I never get video back.  If I try to play a movie, recorded TV, or live TV, the computer will chug for awhile and will eventually play sound, but the screen will remain black.  The only way to resolve the issue is to reboot.

It seems like I've taken a step backwards with the official release.  Anyone else having this issue?  I'm running the 9.10  Catalyst drivers.  Audio and video connection is through HDMI.

It's been hit and miss for me too with sleep and the 780G, sometimes it works, sometimes it doesn't. No real rhyme or reason to why either. If it's any consolation, you can just hit ALT+TAB and your screen will come back, but you'll probably lose the HDCP handshake. I just use hibernate now instead.

Interesting... are you suspecting a video driver issue?  I'm a bit surprised especially since the beta worked without sleep issues for me with the same hardware.

 

I've had / have the same problems with AMD 780G with ATI HD3200 onboard graphics. Very annoying indeed.

 I have the exact same problem with my AMD 780G  - ATI  HD3200.

It's most likely a driver issue because the driver isn't re-connecting the display and the event log spews a bunch of garbage about it. Happened under Vista for me too but under Vista it would never come back from sleep, at least with W7 it comes and goes.

 Going  back to Catalyst 9.8 solved the problem for me, so yes it very much seems to be a driver issue.

 Where does one find older copies of the Catalyst drivers?  Looks like ATI is only posting the current version.

I got the driver from here http://support.amd.com/us/gpudownload/windows/9-8/Pages/radeonaiw_vista32.aspx?&lang=English

 You're right though, it was very hard to find.  The Vista/Win7 driver is the same package.  I also had this issue with my 780G/HD3200 with both 9.9/9.10, the 9.8's work fine though :)

If this is an ATI driver problem it's a bit wierd, as I've had this issue well before version 9.8 was released and now after on 9.9 / 9.10 etc.

 I can't say I noticed the issue was resolved on 9.8 I'd have to role back and try it out again.

Has anyone reported this to ATI support directly?

 

In the past I had this issue with my system, but the upgrade to windows 7 seems to have "solved" this problem so far.  Then again my sleep settings may also be different then yours.  Just wondering what you are using for sleep mode in the bios: S1, S3?

As an aside AHCI is not enabled on my media center box (despite having SATA 3 Gbit/s drives) due to it causing random crashes.  May have been tried in the past, but thought I would offer some other possible alternatives.

I also use S3 sleep and Sata in the Bios is set to native IDE.

 

 

This is a driver problem.  I am running Win7 RTM 32-bit (clean install) with Catalyst 9.9 and 9.10 on a GA-MA78GM-S2H with Athlon X2 BE-2300 and 4GB RAM.  These are the problems that I have found:

1. Video playback will stutter if UMA frame buffer size is 128MB.  This always happens regardless of sleep/resume.  Using a frame buffer size of 256MB or 512MB fixes the problem.  This happened with Catalyst 9.9.  Haven't tested it with 9.10.
2. No video and intermittent audio on playback after resume from S3 sleep.  The Windows UI is also very slow to respond.  This problem happens consistently with Catalyst 9.9.  With 9.10, I've noticed that you can sleep once for a short time (one minute) and it will not happen but it came back after a second sleep of a longer duration (hours).  Not sure if it is the sleep duration or number of times you sleep that causes the problem.

The video performance degradation seems to impact MPEG-2 video playback (DVR-MS, WTV, DVD).  It does not impact WMV.  If you disable DXVA2 hardware acceleration, the problem goes away.  I do get some minor stuttering using only the Microsoft software decoder with no hardware acceleration.

Strangely enough, this is the exact same hardware that I was running Vista x64 on and I had no problems with MPEG-2 playback.  I also have a 690G box and it playbacks MPEG-2 video flawlessly with Win7 and hardware acceleration on.  Go figure...

The sleep/resume problem has been filed as a bug against AMD/ATI.

You can turn DVXA off using this registry hack:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SCrunch\CodecPack\MSDVD]
"DXVA2"=dword:00000000
"DXVA"=dword:00000000

This is pretty much the same list of problems I am having on a fresh 785G install.  I have not activated my Win 7 install so I think I will be going back to VMC until these kinks get worked out.  The stuttering on 1080i recorded TV is killing me.

 Wish i'd noticed this thread earlier. I'm getting exactly the same problems with the Win 7 rtm & 780g, i had no problems with RC. i just bought a cheap HD4350 and stopped using the onboard gpu. Would be nice when this is fixed so i can go back to onboard and keep the system a bit cooler.
