Many people can't handle if they get too many screws they can turn. They
see Windows, they can increase the buffer size and not more, they are
happy.
But that should be no reason to distribute a "simplejackd" that's
hardcoded to use the ALSA backend, 2 buffers and the same audio adapter
for in and out.
If I cannot make sense of it and become an
"expert" who will unless they have
special information. Do the expert study the coded, basically become a
developer. ?
With software, a lack of proper specification and scriptable advice, leads to
no one being able to come to grips unless they go study the code - even if the
application is dead simple. I dont want to do that and shouldnt need to as
just need to be a user in this case that wants to become an expert if
possible.
As I wrote before: Most of the confusion results in the many audio
architectures available for Linux. That's one of the reasons for audio
oriented Linux distributions.
But the other way (using my main PC for audio, too) is possible. I did
it and after I understood that Pulsaudio can be a problem I configured
it to
- not autospawn
- output via jackd
and start a script automaticall when logging in that handles it all for
me. There are many, many other ways to do it but I am a more technical
guy and want it simple and reproducable.
