Thanks.

That depends. Obviously the idea of different input- and output-devices
was to circumvent the OSS half duplex drivers. Today this problem should
be solved by using ALSA drivers. I don't know if there is actually half
duplex sound hardware used in current consumer devices.

So back in the day one would want to run one NAS server making use of
two half duplex soundcards (sound blaster...) and would have to use two
mixer devices to control them. It seems noone actually did this as it is
not fully supported by the voxware server...

In my case I configured the S/PDIF out of the on-board sound as one OSS
device and the normal "analog" in/out hw as another. The sound card
mixer controls all of these devices so I don't need seperate mixers.
