AOSS

 -- real player v10 does not work with alsa, only oss (why???)
 -- use alsa's oss emulation:

 -- apt-get install aoss

 -- edit /usr/local/RealPlayer/realplay (or whatever):


        # ...below these 3 lines...
        if [ -n "$LD_PRELOAD" ]; then
            echo "Warning: LD_PRELOAD=\"$LD_PRELOAD\""
        fi
        # ...add these 3 lines
        LD_PRELOAD="$LD_PRELOAD:/usr/lib/libaoss.so"
        export LD_PRELOAD
        echo $LD_PRELOAD
        # ...end (last line for debugging purposes only)
