I'm using ubuntu 12.04 LTS - 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
Googli'n around my first fix attempt was installing the package "oss-compat" - but the lack of success led me to find out it is just a misleader - an empty bogus package.
Then I tried:
$> padsp pocketsphinx_continuous ... ioctl(NONBLOCK) failed: Invalid argument
Finally, the (dead?) sphynx wiki FAQ states:
compile pocketsphinx with ALSA support by installing alsa development headers from a package libasound2 or alsa-devel
Alsa-devel does not exists in my distro, but I've installed libasound2-dev and gstreamer0.10-pocketsphinx - then re-compiled pocketsphynx - no changes.
Now I'm out of ideas and the sphynx forums seem to be down. Anyone?
