This is a weird error message. Don't know whether /dev/dsp exists or
not - worth checking.

I don't know why you seem to have 2 sound cards but I'd have a look at
getting the Intel sound card going. Put:

snd_hda_load="YES"

in /boot/loader.conf

Reboot & then see what kldstat(8) and mixer(8) tell you. e.g: on my machine:

$ kldstat
Id Refs Address            Size     Name
 1    4 0xffffffff80100000 6f8750   kernel
 2    1 0xffffffff807f9000 1a6e8    snd_hda.ko
 3    2 0xffffffff80814000 66408    sound.ko
 4    1 0xffffffff8087b000 1b70     coretemp.ko

$ mixer
Mixer vol      is currently set to  30:30
Mixer pcm      is currently set to  60:60
Mixer line     is currently set to  75:75
Mixer mic      is currently set to   0:0
Mixer rec      is currently set to   0:0
Recording source: mic

I lowered the volume with:

$ mixer vol 30:30

If that looks reasonable have a go at playing an mp3 or wav with
mplayer. Mplayer might give you some debugging output if it doesn't
work.
