hi i have a problem my onboards sound on a asus p6x58d-e conflicts with my ati 6970 hdmi sound basicly playing bad company 2 after 20 mins using the onboard sound the machine locks up no bsod after tracing and trying different workrounds etc. concluded there is a conflict between the two has anybody come across this before, previously i had been using a sound card so never come across this problem unfortunately after buying another 6970 i cannot get to the pci slot for my sound card i have a pcie slot left but it means buying another sound card which i dont want to cheers

Disable the HDMI audio devices on the 6970(s) in device manager?

I would check your sound settings, if you arnt using HDMI then check that the primary sound output is the onboard sound.

Right click your sound icon bottom right beside clock and select Playback Devices. You will have 2 or 3 devices. The HDMI audio should just say ready (Icon is a monitor / screen). If you dont use the HDMI audio you can literally just right click and select disable.

You want to make sure that the first option Speakers which will show your onboard sound under it is set to default by right clicking on it then select that option. It will put a green circle with a tick in it once it is set to default.

to both answers is that that still doesnt solve it i have reinstalled the catalyst software in custom and not installed the hdmi audio but windows still finds its own drivers for it i have disabled it in sound folder in control panel still no diference i have uninstalled anything hdmi related via device manager still no good whatever i do using the onboard sound in game after 20 mins it still locks the pc up now the other way round using the hdmi sound no lock ups or if i put my sound card in no conflicts if my monitor had a dvi socket i would use that but its only dsub or hdmi
