I've been having trouble getting audio to play since purchasing the software. I have a soundcard installed (X-Fi Titanium HD), but I'm just using S/PDIF output on it. The on-board realtek system is disabled at the BIOS level and does not appear in the device manager at all.
I've been using this setup for quite some time, running everything from other media players, games, and normal system audio. Any time the DAC engages, there is a relay that clicks. It will remain tripped so long as the DAC senses that a program is ready to send audio. For example, if I hit play on a media player, it will trip, and when I hit pause, it will remain on, ready to play the moment I unpause. If I hit STOP, it will stop and the relay will disengage.
Now.. that's all relevant because PowerDVD 16 Ultra will trip that relay, but no signal is sent. Furthermore, it seems that so long as anything at all is playing PowerDVD, it hijacks the entire audio output stream and NOTHING else will play. This is not a behavior I want. I cannot seem to find a setting to change this.
Signal path is set up as Software -> X-Fi S/PDIF optical output -> Schiit Audio Bifrost Multibit -> external power amplifier -> Speakers. Obviously the amplifier is getting nothing. It was built in the 70s and has no digital inputs, so it's not really relevant.
