Dear all,
it turns out that my device, USB Audiophile, does not seem to
be able to capture audio, which makes it almost useless for me.
Now the question is: Can you suggest a reliable USB soundcard
that works well with Alsa in full-duplex? Say between Eur200-400?
thanks a lot

Are you sure it doesn't work with capture? What does jack say?
Maybe you don't have reading permission on the device. Try chmod a+r or
setting up a group for audio and adding your user.
thanks a lot

That is no guarantee. If the sound card doesn't have USB-IF logos (other
than the trident describing the connector), and the "USB" Audiophile
doesn't have them, you need to be wary.
I used to own a M-audio Quattro, which is listed in the Alsa sound card
matrix, but it really doesn't work properly. The sound card isn't USB
audio compliant, M-audio knows it and will not do anything about it and
they don't have to as they don't use the USB-IF logos which would make
them responsible for being compliant.
I'm not saying that this particular card won't work. I'm just saying
that you shouldn't trust specs telling you "native USB compatibility".

So can you suggest some USB-IF cards?

I used ego-sys u24 waveterminal & U2A since many years it's great job,
sound are really good quality, and it's straight recognized (alsa/oss/jack).

Jack can't configure capture channel (or playback), in fact Jack
doesn't work at all with that device. It says it can't set the hardware
sample formats. This is also a problem with Alsa, using hw:num.
The device works on playback through alsa plughw and OSS
emulation. But when trying
to get input from plughw:num, nothing happens (no sound).
It's very fishy.

Have you checked the input volume with 'alsamixer'?
About Jack, I have a Zoom G2 guitar fx and for some reason I have to
plug it in after the boot to get it seen by alsa.
Anyway I thought the snd-usb-audio module worked with any 'native USB
compatible' card.

The USB card does not have mixer elements, so nothing can be
done about it. I've heard that M-audio cards took some liberty
with the USB spec and so they weren't very well supported.
In sequence, I tried a M-Audio quattro. This still has the
same Jack problems, but when using alsa or oss directly it
works in full-duplex. However, the quality is not great and it
clips easily. In other words, not very usable.
