[ubuntu-studio-devel] Ubuntu Studio and Pulseaudio

Hi all, 

although pulseaudio wasn't causing the problem I was
having with this particular instrument, when I run "top" or "htop" in
the terminal, pulseaudio is always near the top of the list of threads,
even though I have never used it. So I did uninstall it (remove rather
than purge) and things still work fine as far as I have seen so far.

Although I don't use pulseaudio and I don't know it very well, I have
read from many people who use linux for audio production that alsa and
jack are the preferred systems. 

It would be nice if Jack would connect
to Firefox automatically; as things are right now it doesn't (afaik)
without a specific "flash-to-jack" file that I have used on another pc
but not the current installation. (I don't think it's in the
ubuntustudio repos either..) Or maybe there are other, better ways to
connect Jack to a web browser, I don't know. Perhaps it's the web
browsers' responsability to allow connection to Jack..?

the pulseaudio package is removed or replaced by a dummy package? I'm
not aware of any app and I don't see a reason to have pulseaudio
installed, if a user doesn't want to use it. IIUC the OP doesn't use
pulseaudio at all. On my Linux installs I never experienced an issue
with pulseaudio removed or replaced by a dummy package. I never used
