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?

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!
