    Do you have any other programs at all accessing the sound card? Things
    like the sound server for KDE or GNOME?

    Is AX.25 working properly in 2.4.24? I was under the impression that it
    was never reliable in 2.4, and fixes are going straight to 2.6. I'm
    still running 2.2 on my packet machine.
