Ive tried to search this up, but so far I haven't found good results. I have a Sound Blaster X-fi PCI-E and the Radeon 4890 HDMI audio for outputs. I have them both working separately on the audio devices list on Vista Home Premium. I FINALLY got screen cloning to work in games, but audio will only output to one or the other. This depends on what I have set to default. Is there anyway to get Vista to output all audio to BOTH devices? Thanks in advance.
