I'm the (un?)lucky owner of an M-Audio Fast Track Pro USB audio
interface and I'm having some serious problems getting this device to
record audio reliably under Linux.
I've been using arecord and occasionally Audacity for all of my
testing. My problem is this: Recording a take works about 80% of the
time. In the remaining ~20% of cases, the captured audio is extremely
loud with severe digital distortion. Once this problem shows up, it
persists for any subsequent takes. The only way I've found to make
the problem go away, at least temporarily, is to power-cycle the Fast
I considered the possibility that this particular device might be
defective, but it seems to work wonderfully under Windows.
I'm calling out to other Fast Track Pro users in the hope that someone
out there has encountered the same problem and better still, found a
Any suggestions at all would be greatly appreciated!
I currently don't have a microphone of any sort. I don't generally do a
lot of audio recording, but I do sing (sort of), play a Garcia Concert
Model 3 nylon string classical guitar, and occasionally do silly things
like play my collection of wind chimes ...
So - what would be a good, reasonably-priced mic for those uses?

This is my first email to this list. Apologies in advance if I break any
conventions I am unaware of.
I am a long-time musician, but just getting acquainted with audio in
linux. I have a very simple goal of getting sound from a plugged
instrument to my computer via a usb-interface, the Cakewalk UA25-EX,
which I know works with linux.
So far the instrument's output is received by the interface, and the
interface is recognized by the computer. I asked in the ardour forums on
how to get ardour to recognize that the input for audio is the usb
interface. They suggested <https://community.ardour.org/node/15577> I
use ALSA instead of jack to connect to Ardour. The interface of Ardour
allows me to select the Cakewalk interface as input and output, but when
I play the instrument I see that while the interface gets the signal,
the audio is not received by Ardour. If I change the input to my
laptop's microphone, then I do get a signal. The problem, then, lies in
the connection between the interface and Ardour (or the computer?)
I checked the Alsamixer levels and they are not at 0. The advice from
the Ardour forum was to contact this mailing list, as I probably need
some help checking the connection of the usb interface to the computer.
Thanks in advance

Extensive work went into this creation.
I wanted the tune to create a feeling that this is one solid composition,
not a soundtrack with distinct segments, but something rather like an ocean
which is in one instance is calm and in the other - furious. But still just
one single ocean.

nonexistent places important.

Has anyone on the list used a device with a Freescale/NXP i.MX6 processor
and used the ALSA drivers for the on-chip audio? I am interested in a
device with that processor, but I don't want to purchase one without some
verification that audio is usable.
