you really have not provided us with much information
on the nature of
the problem you are seeing.
Well my question was mainly about what sound system I
should use.
dozens, hundreds, perhaps even thousands of
us use ALSA and layers of software built on top of ALSA every day to
play gigabytes of audio, and have not noticed the error you describe.
English is
not my native tongue, I am sorry if I gived the feeling to critized
ALSA.
perhaps you should be a lot more specific about the
s/w you are using
and the error you think you are encountering.
Well, in order to settle the matter,
the wav file is available at
http://maleelma.free.fr/lemmel/test.wav.bz2,
and this is my software and hardware configuration :
- amarok 1.4.1-3
- xmms 1.2.10+20060901-2
- alsa 1.0.12-1
- linux kernel 2.6.17.8
- lspci : ALi Corporation High Definition Audio/AC'97 Host Controller (rev
01) [a 939SLI-eSATA2 motherboard, with Realtek ALC 660 5.1 channel CODEC with
HD Audio]
- no asoundrc file
the wav file contains BIP sound, first on one channel, then the other one.
File created with audacity.
as for time drifts when using JACK, forget about it.
JACK-based software
is essentially locked into the hardware.
Well I work with a Magnetic Resonance
Imaging machine (MRI), and the generated
sound must be rather accurate : the software is allowed to have a time
drifting of 1 milli-seconde in sound generation.
I was considerating that small wav files (about 3secondes) pre-loaded, will be
a good choice, what do you think ?
