This is strange. Can you elaborate on your hardware configuration?

There is also a kernel Oups when Skype is segfaulting:

Maybe the code is sensitive to the existince of the sound devices and
that the functions actually return something. Maybe a function like
[quote]
int soundDevice = open_sound_device( ... )
[/quote]
has soundDevice == NULL, which is then passed to the kernel in the
next function.

Maybe ALSA sound devices are not installed really properly on the
Linux I am using.

CODE


shell> aplay /usr/KDE/share/sounds/KDE_Error.wav

ALSA lib confmisc.c:550:(snd_determine_driver) could not open control for card 0

ALSA lib conf.c:3463:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory

ALSA lib confmisc.c:387:(snd_func_concat) error evaluating strings

ALSA lib conf.c:3463:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory

ALSA lib confmisc.c:945:(snd_func_refer) error evaluating name

ALSA lib conf.c:3463:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory

ALSA lib conf.c:3932:(snd_config_expand) Evaluate error: No such file or directory

ALSA lib pcm.c:2068:(snd_pcm_open_noupdate) Unknown PCM default

aplay: main:508: audio open error: No such file or directory



I hope this helps. I don't think it has something todo with the hardware
itself...

Many thanks in advance...

Mind you, skype does not have a native alsa driver (see the sticky posts on top of Skype for Linux forum for a Sound FAQ).
And there's apparently something weird going on with your audio device, please consult your distribution local support/ml/irc first.
