Behringer UMC404HD cannot be set to Stereo.
When using the Behringer UMC404HD, the only options in PAVUControl are:
- Analogue Surround 4.0 Output + Multichannel input.
- Analogue Surround 4.0 Output.
- Multichannel Input.
This means that anyone playing games on this device with headphones has to use the Monitor A/B switch constantly to switch between sources. Games like Saints Row - Gat Out of Hell have the voiceover for FMV's playing through one channel, but the other sounds coming out the other. It's not the same for all games either, it seems to be random.
I haven't tried it with speakers yet, let me know if you want me to test that too.
