Lost sound in ATI Radeon 9000 TV display

Hi all,

I've got an ATI Radeon 9000 with 64mb ram running on a Windows XP box (AMD not Intel) and have recently lost the sound in the TV setting only.

I have normal computer sounds, as well as Windows Media Player, ITunes, etc. but nothing when the TV display is used. Also, the picture is a lot shakier than it use to be and sometimes randomly goes into slow motion.

Not sure when it happened since I haven't used it for a while, but I'm assuming some other program I installed messed things up. When I first tried to launch it, it wouldn't work at all so I reinstalled the ATI software - still nothing. Updated to the most recent drivers, remote wonder software, etc. and got the picture back but no sound. ATI knowledge base offers no solution.

Most recently installed software is graphics related (photo and video editing) and includes ULead Video Studio, Corel Photo Album 6, Ding and all Windows security updates except SP 2 and Malicious tool remover (tried when it first came out but Comcast doesn't like it on reboots).

The only hardware changes made was a Firewire card installed and a new wireless router for use with Vonage.

Any suggestions would be appreciated since baseball season is back and we'll be using the TV more.

If you lost the sound...

...try reinstalling the drivers for the sound card or onboard sound or whatever you use.

Long shot

This maybe a long shot and i'm not trying (very hard) to insult your intelligence but how are you connecting tv to your video card?

You stated that you have all your computer sounds but no TV sounds...sounds to me like you got your video input in but no audio input.

input the audio or read the manual

Some if not all of the ATI AIW cards

In reply to: Long shot

require an audio lead to be plugged into the input of the audio card for sound. Recheck that by unplugging and reinserting. You should hear some static noises when doing this. If you still do not have sound, try a different jack- you may have out it in the wrong one. If still not sound, try a look in the audio control panel, it may be switched off by accident.

Thanks for replys

Thanks for the replys folks. First, I had updated sound card drivers before posting - I should have may that clear.

Second, the video and sound input connections are correct and the same as they have been for about 2 1/2 years now. Cable from outside into the cable outlet on the card, sound output from the video card to the "line-in" on the sound card as per the manual.

I made some progress on the sound issue. Apparently, everytime the TV program is launched, it is muting the "line-in". I unmute it, close TV, reopen it and it's muted again.

So my question now is, is there a way (registry hack or whatever) to disable the mute function of the "line in" so I don't have to go thru this each time? And which software might I have installed that would cause this change after all this time? Or could it be caused by having VOIP for phone service (I just got this in Feb) even though I'm not using a microphone or anything? I have a regular phone hooked up the router to use.

Also, still have the slow-mo picture and can't seem to get that corrected. Sound is right on target with regular TV but the picture is at least half speed. I have already uninstalled all ATI software and reinstalled and it's still a problem.
