Ok, so now I understand your need to have multiple devices on the same card. Point taken. I am still not clear on the need to expose 4 devices, out of which 2 are known to be non-functional. Why not expose to PulseAudio the only two devices that are configured and functional? And to go one step further why not present the devices if they are connected to a receiver? -Pierre
