Hello,

 I am a newbie in the linux audio world and I have some stupid questions:

 I want to wrote an ogg player with great quality playback. I've already 
look at some other linux players and I've search this mailing list to 
find some answers. It seems that two APIs are interesting: ALSA and Jack. 
But i have not find some comparisons between these (and others) APIs 
concerning the output quality (regardless the sound card).

  Can someone give me some advice(s) about what API I should use 
(comments, links, etc...) so that I could start working on it?

I would like to mention that I am not concerning about portability (only 
linux platform) or easy programming, and I just want the best quality 
output for this player.

I hope this is not the most stupid question of this mailing list :)

thank you

best regards

V.T.

Well, ( like I understood it ) the quality of both are equal. If yes, you just have to know:
1.) jack  ( http://jackit.sourceforge.net/ ) is easier to code, and the USER decide
which "options" are used, not your programme.
2.) alsa ( http://www.alsa-project.org/ ) is goes "deeper" into the hardware space,
your programme can decide which "options" are used and its sometimes harder
to code.

But this wasn't your question ;) .
jack does NOTHING with quality itsself, because jack is a user-space daemon other
apps connect to and send data to, which is then outputted via the currently used audio-driver.
And this is alsa ;)
( Or I think so - MY jack version ( Debian unstable ) does NOT have other possibilities,
my jack can only use alsa. Maybe this changed in newer versions! )
