I've been using Mandriva for a very long time now, as it's been good
to me for audio work. But, they are having financial troubles and
looking to be bought out. Maybe they'll survive that, and maybe they
won't. At some point I might want to change distributions.
To piggyback onto this question, how far is Linux audio
performance a distibution dependence thing?
I think it doesn't matter too much, there should only be a difference in
how much work there is required to set it up properly and whether the
distribution messed something up.
To wit:
1. There are some kernel settings related to audio
performance. These are easily found for those interested
to compile their own kernel. Can't pretty much any
kernel be run from any distribution?
I guess pretty much, but some stuff still needs to fit together. Some
distros patch the kernel heavily, others don't do it at all, it totally
depends. Obviously it's probably safer to run a preempt-rt patched
vanilla kernel on a distro that doesn't patch the kernel than on one
that patches heavily.
2. Isn't JACK and ALSA configuration pretty much
kernel
indpendent and distribution independent? For example,
you can start the JACK server with whatever parameters you
want, and ALSA asoundrc is also independently configurable.
Yep, that's all the same, except for version differences. Some distros
are way behind the latest release.
3. Each application requires some configuration,
including
compiler options during build. Do some distributions handle
this so much more wisely than others? For example, is the
Planet CCRMA version of Ardour better than the Debian
version?
Curiously yours,
Joel
It may make a bit of a performance difference, but I don't know whether
it's significant. Some distros optimize their binary packages for i486,
others for i686 and some are source based and optimize for the machine
they run on. No idea whether it really matters.
I'm quite sure any distro can be used for audio, the specialized ones
have done some work for you, some are more up to date than others, some
mess things up one way or another. That's all there is IMHO.
