OK. My understanding is:
* There is /dev/dsp0 which corresponds to pcm0 (snd_hda).
* /dev/dsp and /dev/dsp0 are the same. e.g.:
$ ls -l /dev/dsp /dev/dsp0
crw-rw-rw- 1 root wheel 0, 83 Dec 14 20:55 /dev/dsp
crw-rw-rw- 1 root wheel 0, 83 Dec 14 20:55 /dev/dsp0
* There is no /dev/dsp1. But there is /dev/dsp1.1 which corresponds
to pcm1 (snd_uaudio).
If these are correct, will you try to make a symlink /dev/dsp1 which
points to /dev/dsp1.1 via devfs.conf(5)? i.e. Add the following line
to /etc/devfs.conf and then reboot the system:
link dsp1.1 dsp1
