sound recording in Ubuntu 11.04 etoys

Hello,

I'm trying to use the sound recording tool under Ubuntu 11.04.

Either etoys is freezing when I clic on the "record" button,
or etoys quits when I clic on the "play" button.

There is what is showed in the terminal :
----
etoys
sound: /dev/mixer: Erreur d'entrée/sortie
squeakvm: /build/buildd/squeak-vm-4.0.3.2202/unix/vm-sound-OSS/sqUnixSoundOSS.c :355 : dspOpen:  L'assertion « dsp->fd < 0 » a échoué.
Abandon
----

Do you know how to fix this?

Regards,

François

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!

Looks like your etoys vm is using the older OSS sound module. Try using the
newer vm-sound-ALSA for better results.

You may check your mic input levels with a program like Audacity before using
it with Etoys.

I've uninstalled the repository version and downloaded the Etoys-to-go
version.

Recording is ok now.

But it could be useful to correct the Ubuntu 11.04 reposistory
version...

Regards,

François
