I'd like to make you aware that there's a third possibility. "Can't be built against it" is relative- it is technically possible (although not common practice) to work around this. HD24tools for example has JACK support built-in (for Linux as well as MacOSX/Windows), but doesn't require JACK to be available; it is a soft dependency. This is vital for platforms whose users don't usually have JACK available. Without JACK available, HD24tools will try portaudio. With Jack and portaudio both unavailable, there simply will be no sound. This is accomplished by letting the application manually load libraries in runtime, rather than statically linking them in, or letting the compiler generate code to load the dynamic libraries on program startup. I suppose it would be possible to tweak Pulse Audio to have the same capabilities, but it's really up to the author(s) of Pulse Audio to make such a decision. I'll gladly provide the JACK wrapper code that allows this. In any case, I thought I'd make you aware of this possibility. As it allows JACK support to be built-in without it being a hard dependency, it could solve the problem posed by the original poster.

Thanks for your quick response. So will lucid have PulseAudio with Jack support? 2010/2/4 Eric Hedekar : > On Thu, Feb 4, 2010 at 1:55 AM, Samuel Mehrbrodt > wrote: >> >> Hi there! >> >> We are using Ubuntu in church for recordings and sometimes to display >> a video or just play some audio. >> >> Everything works great, when you do not have Jack started.

The Ubuntu Studio team is actively working to get Jack into Main right now as a fix for this, but it's not there yet (we're on our way though). For now, I have seen some posts on ubuntuforums.org regarding PPA repositories that include Pulse Audio built with jack support. Hope that helps. -Eric Hedekar -- Ubuntu-Studio-devel mailing list Ubuntu-Studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
Jack in Ubuntu Studio
Hi there! We are using Ubuntu in church for recordings and sometimes to display a video or just play some audio. Everything works great, when you do not have Jack started. When jack is started all applications which do not support jack can not play any sound. This is e.g. Rhythmbox and Totem. I've seen some tutorials where you could preconfigure PulseAudio to use jack by default. But this was quite difficult and required many steps to do it and I didn't want to do it because I wasn't sure if anything would work after it. So here's my question: Ubuntu Studio is designed for professionals, can't you configure it to use Jack by default? Jack could be started when booting and PulseAudio would play everything over Jack. If this isn't possible, could you just provide an easy way to do this?
