That might not be a sign of trouble because /dev/dsp is the old Open
Sound System (OSS) interface. These days, ALSA is the norm and lives in the
/dev/snd directory. Three useful commands to try out (and example output
with just the built in sound card available):
$ lsmod | grep -E -e '^sound|^snd[_ ]'
snd_soc_neo1973_gta02_wm8753 8808 0
snd_soc_s3c24xx_i2s 4568 1 snd_soc_neo1973_gta02_wm8753
snd_soc_s3c24xx 5192 1 snd_soc_neo1973_gta02_wm8753
snd_soc_wm8753 34228 2 snd_soc_neo1973_gta02_wm8753

snd_mixer_oss 15304 1 snd_pcm_oss
snd_pcm 75564 4 snd_soc_s3c24xx,snd_soc_core,snd_pcm_oss

soundcore 6796 1 snd
(The modules snd_pcm_oss and snd_mixer_oss are for the kernel level OSS
emulation.)
