with HDMI and ATI 4890?  Last response: in Graphics & Displays
I have a 4890 with the adapter going with an HDMI cable to an
Onkyo sr607 reciever. I'm getting sound and video, but when I go
to my sound devices in Windows, it just shows a Mono and stereo
speaker options.  Can I do 7.1 sound with this setup? Or will I
need to wire something else with my onboard sound? How would I
go about doing all of this?  I can't get 7.1 with my hd 4870...
I always just have the option of 5.1, never 7.1 I've disabled
the onboard audio via bios, uninstalled all audio drivers
including my audigy sound card, and reinstalled my realtek 2.67
driver and STILL only 5.1... why don't i have the 7.1 option? My
receiver supports 7.1 PCM... ANY advice is wonderful!  The
driver I'm using is from the AMD Catalyst Control Center. It's
the HD Audio thing that installs with it. Under my sound
properties, I choose ATI HDMI output which goes through the HDMI
and once I do that,
