As I posted, I can not list device hardware with: arecord or aplay aplay -l **** List of PLAYBACK Hardware Devices **** aplay: device_list:277: control open (0): Invalid argument aplay: device_list:277: control open (1): Invalid argument aplay: device_list:277: control open (2): Invalid argument Segmentation fault Always return: Segmentation fault And that why I can not hear anything from speaker or record anything via mic. In history, I installed alsalib 1.1.1 from: ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.1.1.tar.bz2 After that alsalib load fail.
