Graphic Card Dropping Sound

[TheB2B]

I have an Asus graphic card built on ATI chipset, AH3450 with HDMI video and 5.1 surround sound out. When I switch my flat screen tv from HDMI 2, my WMC is plugged into this port, to any other port or input such as my XBox, when I switch back I have no sound and need to reboot my PC.

The sound icon in the system tray will sometimes show a red X other times not. Also on occasion when I switch the TV back TV says no input signal and I have to do a hard reboot. Then all is good again, until I decided to play Xbox.

Any thoughts on a possible solution.

um... there should be a way to disable it in either the device manager or ccc

 

[TheB2B]

I don't want to disable it, if I did then I wouldn't get any sounds through my surround sound system, if I understand your response correctly.

 

[thepizzaman]

hm... and it only happens when you use your xbox?

 

[TheB2B]

Happens whenever I switch my TV to another connection, say XBox, or if I turn off the TV but leave the PC run. Another way to say it is if the TV switches focus to another device or powers off.

I have as a test uninstalled the "sound card" in device manager then reinstalled it without rebooting the PC, this doesn't resolve the problem. If I uninstall the sound card portion of the video card and if there was a red X on the sound icon in the system tray it will remove the red X on the speaker icon in the system tray and when I hover the mouse over the tray icon it will show sound fluctuation on the meter but no sound.

I have also ran as a test unpluging the HDMI cable from the PC and plugged it back in, no change. I have also installed the latest drivers from ATI, this has improved the picture quality and sound play back but has not resolved the dropped sound issue.

hm... does your motherboard have 5.1 surround sound? if so just drop the cards sound

 

[TheB2B]

Documentation says it does but it is not true 5.1, that is it is missing, depending on how you hook it up, either the back speakers or the front speakers with no output of the sub-woofer. Plus the receiver needs to be reset, its an older one, so it requires selecting different settings. With the TV input I can set it and forget it.

 

[thepizzaman]

do you have about $15 you could spend on a surround sound card? haha thats prolly the best way to do it....
because i have no idea why it would do that....

Disable it, reboot, then re-enable it.

 

[TheB2B]

I'm in classes until late tonight, I'll give this a try tomorrow and let you all know if it works.

Tried the disable, reboot and enable, same result.

As for a sound card, I'm currently un-employed and going back to school with a family. Not going to have an extra dime much less $15 for a new sound card. Guess I'll have to deal with what I have.

PS I wouldn't recommend the purchase of the ATI 3400 series video card. I have returned this one once already due to card hardware failure and now problem with sound dropping out and intermittent dropping of the video stream if

a. TV is not switched to the pc when it is started up
b. on occasions dropping the picture just like the sound is dropped but only intermittently.

hm....... idk what to tell you
