in reply to Sharing Sound card / Remote Media PC.

Your sound card's device node under /dev will be owned by a group called audio (or similar).

Add your web-server's user (eg: www-data, or nobody) to that group.

    Thank you, that sounds right. But...

    I have added the "nobody" id and the "apache" id to the group "audio" which owns /dev/audio (which is a link to /dev/sound/audio, which is owned by root.) But it seems to make no difference.

    I can play my script from the command line, either locally or through ssh, but not through a web form. (useless web form below).

    mplayer is running, I can see the feedback on the web browser, but no sound. 

    <html>
        <head>
                <title>
                        Test file
                </title>
        </head>
        <body>
                <h1>Test file</h1>
                <p>test data
                <form action="/cgi-bin/PlayPod.pl">
                        <input type="submit" value="play pod">
                </form>

        </body>
</html>

      Two things:

      Are you sure the webserver is running as nobody?

      Does PlayPod.pl know how to start the music and give control back to the initiating terminal (in this case the web-server via fork) ?

        Figured it out. I needed to restart the web server(rebooted actually) before it recognized the new group assignments.

        I am expecting use of "system" should allow control to be retained by the web server. It does play the sound file to completion, or if I hit the back button, the file is interrupted.

        I think the web server actually runs as "apache", but I think it may run cgi as "nobody".
