However, the strace from the previous email did not find any custom ALSA configuration files that could affect the outcome. Thus, I conclude that you, or maybe some stupid script that you ran, modified some file in /usr/share/alsa in a bad way in the past. Please reinstall alsa-lib (which may be known as libasound2 in some Debian-based distributions). Or, please tar up the whole /usr/share/alsa directory and send the tarball here, and I'll look what exactly is damaged there. -- Alexander E. Patrakov
