I'll be interested to hear what you find. Based on the Main Inclusion
Report for Jack which you authored, I am expecting Lucid Studio to
have the following functional out of the box :
- xine, alsa-plugins, portaudio, pulseaudio compiled with jack support
so that most applications would still be able to use the audio
hardware while jack is running (e.g. being able to use Skype without
first shutting down jack), and not having to suspend PulseAudio to use
- general applications should have transparent access to firewire
devices via pulseaudio/jack/ffado for audio input and output.
I realise that for serious audio work one would dedicate the
workstation to audio and deliberately shut down everything not needed,
so the above would not really be relevant, but I think that many
people (like me) just want to have a reasonable audio capability
without dabbling in arcana, and without making the machine useless for
