Lars,
Everything looks right in your ecasound setup. Nama
correctly identifies the .wav file as stereo. Your log of
ecasound activity indicates the setup ran. Ecasound
processed several setpos commands. I see setpos 303, engine
start, then setpos 0, setpos 63.
The typescript file indicates a test failure that means
the distribution was not installed. According to
the mail that you sent on Christmas Day, you
succeeded in installing Nama. Does that mean that
v1.213? Did it install without errors?
As far as I'm aware, you're the first user of Nama
running pulseaudio. I know that most serious audio
users on Linux disable pulseaudio. Still, if
ecasound Setup.ecs at the command line runs and outputs sound,
I would expect the Nama with the same project loaded
to output sound as well.
Regards,

Hi, Joel!
Thanks a lott for your help!
I just realized that if I wait 15-20 seconds after starting the
play, the sound is heard. Strange.
That is curious. Does the WAV file play from the beginning when you
hear it, or is the position already 15-20 seconds into the
recording?
The position is moving, so it's e.g. at 40 seconds. It seems that the
first seconds of playing (although it's silent), moves faster than the
real time. So if I press space and wait 1 sec. before stopping, the
posistion is moved let's say 30 secs forward.
Did you edit $HOME/.namarc ? It's not clearly documented, but
the frequency: entry in the abbreviations section
should be set to the sample rate of your soundcard.
The ~/.namarc is untuched.
In /proc/asound/card0 I have files like codec#0 and codec#3. In codec#0 I
have ...
Default PCM:
rates [0x5f0]: 32000 44100 48000 88200 96000 192000
bits [0xe]: 16 20 24
formats [0x1]: PCM
It looks like default namarc defaults to 44100.
I've not changed that.
The template is taken from config item raw_to_disk_format.
That would affect how import-audio works.
What kind of audio environment ? Possibly pulseaudio running?
Yes, pulse is running.
Other ecasound processes?
No.
If you want to monitor ecasound closely, start
ecasound in a separate terminal as:
ecasound -c --server --server-tcp-port=2868 -d
( -dd gives more debug output -ddd even more.)
Then start Nama, and it will connect to the
existing process, which will scroll
with debugging information while Nama runs.
Please find a typescript file attached.
And/or you can start Nama with -L ECI to
see the ecasound commands.
You can run ecasound diagnostic commands from the Nama
prompt: fs,

There are commands for positioning an audio clip (aka WAV
file aka RIFF), for defining, positioning and processing
regions of an audio clip, and for fades, all that might
be able to cause what you've observed.
So, it may be you may have accomplished something
unwittingly :-) Or perhaps the software is developing
sentience 8-)
The Nama command '3 show-track' should indicate if there
is a region or shift (position offset) involved.

Despite the warning bypass-effect (bfx) and
bring-back-effect (bbfx) appear to work in my test. Like
you, I saw the BYPASSED indicator in the Ecasound 'es'
output, and also confirmed the status of the bypassed flag
in Nama's corresponding effect object.
With `ecasound -c Setup.ecs', it starts to play immediately if I
type start. Also if I use setpos to enter a new position beforehand.
What do you observe when using setpos in Nama? Does it affect the
delay?
No.
Please post the result of the command "3 dump" in this
project.
