ecasound recording in mp3 problem
i am using an iMic usb audio card/mic to record analog audio to mp3
format. i have used this setup on ubuntu 8.0.4 kernel 2.6.19 and it
worked great. now i have reinstalled and am using kernel 2.6.27-7
(amd64)it seems to be broken. below is the output. im just doing a
simple ecasound -i /dev/dsp1 -o /home/filename.mp3, but doesnt record.
if i do the same command but as .wav it does record. you can see the
version im using and the lame version is LAME 64bits version 3.98
can someone help?
thanks todd

Music was my first love and it will be my last (John Miles)
======== FIND MY WEB-PROJECT AT: ========
So my idea was to use some JACK reader/connector which can sent WAV data
to its standard output and then to use 'vlc' which will read these WAV
data on its standard input and will transcode them to FLAC stream (and
will be work as a server for clients too).
I mean this:
ADAT/RME --> JACK --> reader_from_jack_to_WAV | vlc <--- clients
I tried to use ecasound as a 'reader_from_jack_to_WAV' component.
But I don't know how to set it for producing WAV data on its standard
output.
When I type:
ecasound -i ... -o:sndfile,-,wav > /tmp/output.wav
in first step, it is ok, I have output.wav file in WAV
and when I type:
cat /tmp/output.wav | vlc ....
in second step, it is ok too, vlc produces output FLAC stream.
But I need to use them both together in pipe. In this case:
ecasound -i ... -o:sndfile,-,wav | vlc
does not work.
In fact -
ecasound -i ... -o:sndfile,-,.wav | cat > /tmp/output.wav

and
ecasound -i ... -o:stdout,.wav | cat > /tmp/output.wav
writes data in raw format (probably) to output file.
Please - could I use ecasound with WAV on standard output in pipe?
I will appreciate any other idea how to solve my problem
or recommendation to other readers/producers too 
Thank you very much for your help,
Regards,
Milos
