When I tried this with TeamSpeak but it did not work. No mic and no output. This could also be a problem with the way the alsa 32bit emulation libraries are setup on my machine. > > If your application doesn't allow changing the device, or if you want > to change the default for all applications, or if you want to map to > a hw:X,2 device, you can change the mapping with the dsp_map and > adsp_map options of the snd-pcm-oss module.

In /etc/modules.conf I changed alias /dev/dsp snd-pcm-oss to alias /dev/dsp snd-pcm-oss dsp_map=2 and it is now working. The mic works in TeamSpeak and TeamSpeak output goes to the coax spdif output. So I think that everything is now using the coax spdif output by default. At least everything I have tested does.
