I'm using Fedora 16 - sound works fine.

I've tried to execute Pocketsphinx for some tests with voice recognition, but it depends on OSS to work. It crashes with the message:

ad_oss.c(103): Failed to open audio device(/dev/dsp): No such file or directory

I have ALSA-OSS installed but im getting the same error.

What's the output of lsmod | grep snd_seq_oss? If there's no output, try doing modprobe snd_seq_oss. – Free Bullets Nov 5 '12 at 2:24
I tried with lsmod | grep snd_seq_oss but there's no output. And i tried with modprobe snd_seq_oss and there's no output too. What is happening? – user170179 Nov 5 '12 at 2:31

For /dev/dsp to work, the actual sound driver must be loaded (check index 0 in /proc/asound/cards), and the snd-pcm-oss module must be loaded.
