Hi,
as my Acer Laptop only has a via ac97 chipset and one mono (mic) input and
one stereo (headphone) output, I consider getting some additional
hardware.
I have two USB ports and a PCMCIA Card slot. Which one is better to use as
a sound input/output? I mean sound quality and latency.
I am running ecasound on top of alsa 0.9.2 and the 2.5.66 kernel.
Any suggestions for a particular card/device/setup?
Thanks a lot.

PCMCIA is more capable, but devices are much mor expensive than USB
boxes. I run a M-Audio Quattro USB on my Acer.

is it capable of full duplex (digital in and digital out)? and if so - does
it do it on Linux? What kind of latencies are we talking about here? (just
curious - have a laptop myself with USB ports (no PCMCIA))...

Yes, every recent (newer than about 2-3 years) can do full duplex, and
with ALSA supported cards do it on Linux, too. Full duplex isn't
really a feature anymore.

I never measured it...

The problem with the M-audio usb stuff is that it
needs a very specific quality of AC voltage to operate,
which makes destroys the key advantage of having an audio
interface on a laptop. One company researched and developed
a battery pack for these devices, but admits that hum
is introduced into the signal.
I've been looking for a long time, and decided that the
Apogee Mini-me is the best solution, but at $1200.00.
If you don't cream over 24/96k, you can look at the
mbox. Edirol has one with great features, but apparently
the mic pre's are very noisy. VXPocket looks good,
but has no phantom power. These can be had on ebay for
a reasonable price however.

Edirol has an audio out only with rca outs and doesn't need extra sound,
its only 16 bit 4100khz, but should be pretty well perfoming, they're
cheap too, probably around $60 used, some people also had talked about
being able to use the iMic with audio output, and that doesn't need extra
power.

thanks for a very intersting info! I shall check those out more, meantime, I
am thinking about these two i've digged out on the net:
http://www.winic.com/2178sp.htm
This one is really simple usb<->s/pdif converter - after emailing to
manufacturer (Taiwan) and getting price list they are about $30 for single
purchase plus shipping, etc. - sounds kinda good to me and considering that
it is strictly very simply device - there should not be much issues with
compatibility (manufacturer states that device is full duplex and USB audio
standard compliant)...
the other is from www.waveidea.com
it is called UASC-1 (more expensive), but has all online purchashing
fascilities, etc... don't know which way to go yet - but just thought people
would find it interesting (esp. the first device - appears to be real
cheap... - yeah i know it is gitial only - but that means that it modular
(i.e. can use either high quality AD/DA converters or a cheapish DAT
machines/ minidisc players, etc.))

mmm, am I correct to understand that VXPocket is pcmcia? (my laptop has only
usb :-) - iBuddie desknote )

Some newer M-Audio boxes like the Audiophile USB don't need an
external power supply.

You had me excited there for a second, but I need a pair of
mic pre's, which this box doesn't have.
