(solved) Error indicating "alsa" issue; @capturing screen within skype (Xorg7.4)

[tinypoodle]

Code: [Select]

command &

[floppy]

with "nice -n 15 wxcam &" (or 10), the "alsa" error messages dont come anymore before it breakdown.
It scratch now  with
"aborted"
or
"segmentation fault" (right after capturing the skype webcam window).
So, this is a type of progress. Thanks all.
I wait a bit more before I mark this thread as (closed).
