I have the ATI Radeon 9800 Pro AIW card for 5 years now - a half decent card for playing games and watching TV. However, after installing the newer Catalyst drivers and MMC for the last year or so, the TV function suddenly started having some major problems.

For one, I always hear TWO sound channels instead of just one, both are the channel's soundtrack, but one is always lagging behind the other so it sounds like an echo. If I press the mute button on the MMC panel, then the echo (extra soundtrack) disappears but I'm left with the soundtrack that is being heard in advance of the picture (i.e. when I hear voice speaking, the actor hasn't opened his mouth yet). However, if I were to record in DVD resolution, the resulting video file has correct soundtrack and timing.

what can I do to fix this?

Thanks!

I have the same problem as you, did you find any solution?

Hello all,

first, for this card I would recommend to stay with the slightly older "analog" capable drivers:

Catalyst 5.10/6.2
WDM_SP (still included with both of these versions)
MMC 9.03
Remote Wonder 2.5

Before you do this, you would need to completely clean all "modern" Catalyst driver remains!

But if you want to use the latest drivers, that might be possible too. The problem you are having is caused by the A/V Streaming T200 driver, in combination with the still installed external or internal Audio cable. When using the latest drivers, you do NOT need the Audio cable going from the AiW to your sound card anymore: the echo is caused by this cable still being connected.
As a temporary solution you could use the Audio settings for your sound card and disable the Line-In and/or Aux-In, where the AiW is connected to.

Yank the line in cable out and see if that fixes it. If not then go ahead and reinstall older drivers and see if that fixes it.

Can't see why DVD quality recording would alleviate the problem unless the problem to begin with was a codec issue?
