I noticed in the discussion on Ken Restivo's EEE-PC that he is using the
MAudio FastTrack Pro. I had looked at that device, but when I looked at the
Alsa soundcard matrix, it wasn't listed. Is it working out of the box?
Another USB device that I thought looked good was the E-Mu 0404 USB. It is
listed as not implemented yet. Is anybody using that out of the box yet?
Any other ideas? I'm looking to replace my venerable Edirol UA-20 with
something a little more modern since I've never been able to get its midi
and audio working together. In advanced mode, midi works but no audio and
vice-versa.
Best regards,

General point: there will be no linux support for USB2 audio devices
that looks anything like what currently exists for USB1. There is no
"class compliant device specification" for USB2 audio at present (and
my guess is that there will never be one). This means that just as
with PCI devices, each and every device (or certainly each and every
chipset) needs its own distinct driver, written one by one by one.
Yet another incredible SNAFU from the audio technology industry - the
folks who bought you MIDI and then lost the plot, started squabbling
amongst themselves, and then the show was cancelled.

That's how it looks to play out to me too. Brain dead. There is a lot of brain
dead plays from "world class" companies. It boggles the mind. A mom and pop
making some of the mistakes I see is one thing, world leading enterprises
making them is another thing entirely.

Does this mean Linux USB Audio is in a fail state? And Linux FireWire Audio
is leading the race?

This might encourage more companies to develop and test with ALSA so
they can put the little "compliant" logo on their packaging.

By defacto standard that would imply that is is not the official
standard anyway. However there is a strong case for the ALSA usb-audio
driver to be the official standard too as it is completely open sourced.
Might be worth the consortium approaching the usb standards authority to
get them to assess the compliance of the driver...

Most of my changes are for devices that deviate slightly from the

changes in their design, such as, e.g., M-Audio devices where multiple
streams have to be configured together, or the UA-101 where the driver
has to derive the playback sample clock from the recording stream; and
I have not added support for those features.
As it happens, Roland and M-Audio sat on the committee and put exactly
those features into the 2.0 specification.

I tried an UA-25EX which lacks separate volume control for output and
headphones. My sample was also defective. Lexicon Omega also does not
have separate output and headphone volume control so it did not work out
for me, but if you can live with the plastic case it sounded pretty good
to me. The other two devices that I considered was a TAPCO Link.USB and
Alesis iO|2. Mackie which builds the TAPCO device had quality problems
at the time, as in not shipping products, so I ended up with the iO|2 by
process of elimination. The iO|2 sounds ok, but the loud pops on power
on/off does not exactly inspire confidence in the product. The form
factor is a bit strange with some input connectors on the top of the
device.

Hi -
I too use an M-Audio FastTrack Pro with an Eee-PC (pic:
http://www.flickr.com/photos/danstowell/2402517009/ :)
It works out of the box and is in many respects great. However you
only get TWO audio outputs, not the full four. Big warning there if
you ever want four outputs (which I do quite a lot these days).

I have an E-Mu 0202 USB (probably similar?)
Basic I/O worked out of the box. I guess using the snd_usb_audio
module. Controls in alsamixer do not work.
Realtime performance appears to be similar to what I achieved with my
old USB 1 card, as long as using 48 kHz. Using other sample rates it
becomes unstable.
Found this (a little outdated) thread, linking to some more information.
http://lists.linuxaudio.org/pipermail/linux-audio-user/2007-May/045792.html
Not that much a recommendation, but at 48 kHz it runs fine and I'm
really happy with it.
