You could try another sound module. What does your "etoys" script look like? In the latest Etoys-To-Go we use this:

# if pulseaudio is running, use it if VM has the driver, or fall back to OSS
if pulseaudio --check 2>/dev/null ; then
    if "$VM" -help 2> /dev/null | grep -q vm-sound-pulse ; then
        VMOPTIONS="$VMOPTIONS -vm-sound-pulse"
    else
        VMOPTIONS="$VMOPTIONS -vm-sound-oss"
        if padsp true 2>/dev/null ; then
            WRAPPER=padsp
        fi
    fi
fi

This prefers PulseAudio over OSS. Older scripts preferred OSS.

You could also try to remove this section and add either -vm-sound-pulse or -vm-sound-ALSA to VMOPTIONS.

Please let us know if you find a working combination!
