Hello,

after reinstalling debian, (now etch , therefore sid) on my Qube2, because of changing to a 2.5" HD (from 3.5") and installing the current debian version I got a Segmentation Fault on every usage of a program which should produce sound :-((

The programs are

mpg123
mpg321
mp3blaster

The programs did work with this qube2, soundcard and mp3-file under debian sid,
but now with etch it didnt work anymore.


Hopefully someone could point me to the problem which is generating the Segmentation Fault.

Here the complete SegFault-Listing...if this could help to find the problem:

The programs saytime and saydate did produce a error regarding the pcm sounddevice.


Thanks
