[linux-audio-user] help needed with JACK options

[Dave Phillips]

Greetings:

  I'm preparing various materials regarding ALSA and JACK, and I need 
some help understanding some of JACK's options. I've consulted the JACK 
FAQ and the jackd man page, the existing explanations are clear enough 
as far as they go, but they don't actually explain *why* a user wants or 
doesn't want to activate certain options. Namely:

1) What will the -m and -u memory options do for a normal user ? Under 
what circumstances is it appropriate to use them ? What exactly does it 
mean to unlock a GUI library's memory, and again, how/when does it 
benefit the normal user ? Are there reasons a user should not enable 
these options ?

2) I understand audio dithering conceptually, but what would be a 
typical situation when I would enable it in JACK ?

3) Is there any particular good reason a user would *not* want -R enabled ?

4) Regarding the "Force 16-bit" option: When would a normal user want to 
activate this option ?

  The FAQ and man pages are informative enough for the remaining 
options. Any help with the questions above will be hugely appreciated.

Best regards,

Dave Phillips
