Raspi, OK, understood.

Streaming via cable or via a RF link?
I have to ask more detailed when my project is running too...

Hi,

News from Wolfson audio on the R-Pi:

Using an ultra fast SD-card silently "borrowed" from
Daddy those overruns from Wolfson audio were still
present but less often and way shorter.

OK, next writing into the unix toilet:
arecord -Dhw:0 -r 192000 -c 2 -f S16_LE /dev/null

Fine, no glitches after hours of recording!

Next trial was piping the output via ssh to
my desktop computer:
arecord -Dhw:0 -r 192000 -c 2 -f S16_LE - | ssh [email protected] 'cat>  
from_rpi.wav'

A growing file named "from_rpi.wav" appeared
in my home directory on the desktop computer.
"arecord" consumes only 1% of cpu load and
the piping secure shell process 19%. Stopped
this when the file size had reached 1 Gb.

NO overruns were noticeable after the connection had been
established. So piping aka "streaming" should work.

BTW after a loud "bang" and some smell from amperes
I'm running the R-Pi (B-type) from a current limiting power
supply now. 5.2 Volts and only 400-500 mA all inclusive.

PS: "dd-ing" Daddy's very private videos back now...
