    I thought this might be the same as the netbook, input muted, but its not. Input is on, amplified and working, tested. Pocketsphinx seems to be having issues.

    oss_compat is installed.

    Beside installing the package you need to probe the kernel module to create the device

    Please read about linux audio subsystem somewhere, also see CMUSphinx FAQ.

    That's all done Nikolay. Seriously. Still getting the same error. Perhaps I'll go try the Ubuntu forums.

    Perhaps I'll go try the Ubuntu forums.

    You also can join #cmusphinx IRC channel on freenode, it's easier to help you in interactive mode.
