I am thinking of buying a E-MU 0202 USB 2.0 Audio Interface. Anyone got
one of these running under Linux?

I've been using an 0404, which I would assume is similar. Haven't found
a way of setting the sample rate, so I'm stuck at 48kHz, where 44.1
would be more appropriate here perhaps. Also, full-duplex mode doesn't
seem to keep up properly, and I've had to resort (for guitar effects) to
sampling with the 0404 and playing back through the internal sound card:
I don't know if this is the PC, a USB problem or the 0404 itself. Oh,
and the 1/4inch jack part of the neutrik connectors are a bit prone to
bad contact.

(And I really /don't/ like creative's power supply. I can't see any fuse
link on it for one thing, which seems a bit dubious to me.)

Interesting, I really need full duplex. I am trying to work out if I can
get a decent external (USB) sound device to work with an audio
measurement software package like Visual Analyzer or RMAA (both of which
work fine with wine).

I use (at work) an EMU0404 with Visual Analyser and with ARTA to do
amplifier and loudspeaker measurements (using a Dell desktop pc). I
have never successfully managed to get full-duplex operation running
reliably above 48kHz. Half-duplex is no problem, but then I can get
that with my own M-Audio Transit.

Obviously (like you I guess), I need full-duplex because I need to
reference the measured output to the input signal.

Yes, that's pretty much it. I do not particularly need a reference so
much as a convenient source of low distortion test signals.

FWIW I tend to use either a CD player or a computer for that. Then use a
recorder to record the results. Where referencing is needed I use one
channel of the recorder to record the stimulus and the other the response.

For example, this is what I did to obtain the results shown on

http://www.audiomisc.co.uk/ArchiveMa...2/Testing.html

which let me assess the in-room response from a loudspeaker, including
measuring the phase/time effects.

I agree that what you use is a matter of what you find convenient. However
I also tend to be concerned to ensure that sources are well defined and
well behaved. An advantage of using a good audio playing device is that
it can deliver good output signals. Given my background in measurement
labs I guess I am not bothered by the idea of using seperate dedicated
items for the different roles in the measurement process.

Slainte,

Jim

No experience with it, but a quick 'google' does return some pages like

http://wa5znu.org/log/2009/06/emu-02...-on-linux.html

Let us know how you get on. I'm still waiting for various makers of USB
sound interfaces to get back to me on the promises about 'providing details
on how to use with Linux!'. :-)

Slainte,

I have no particular desire for this particular device, just one that
will give me full duplex (mono even) 24/192 operation under Linux.

I'd also be interested in that. However at present I've deal with such
matters by having mutliple (non computer) recorders and sources. I still
tend to have the old-fashioned view that it is simpler and better to have
the recorders and sources divorced from a computer whos hardware and
software is subject to continual 'updates and changes' that mean you'd have
to keep re-calibrating and checking if the audio i/o was still working
correctly.

You don't have to put in the updates and changes. For a critical
machine, I'd really recommend that once a working configuration is
found, you stick to it. No updates, no patches, no "security fixes". And
I'd also suggest no general net access to/from it either. Then I see no
particular problem in using a computer as opposed to a reel-to-reel
recorder, for example.
