Are you running a sound server? It can lock up the device, preventing other applications from using it directly. What happens if you use the -vv option to the command? aplay -vv /usr/share/sounds/alsa/Front_Center.wav aplay -vv -Dhw:0,0 /usr/share/sounds/alsa/Front_Center.wav aplay -vv -Dplughs:0,0 /usr/share/sounds/alsa/Front_Center.wav What does strace show? strace aplay /usr/share/sounds/alsa/Front_Center.wav Are there any messages in /var/log/messages related to alsa? When you installed the library, did you check that everything went in the right place? Some distros move things. The standard location for alsa-lib files is in /usr/share/alsa. Check that those files are the files from the package. Then search in /etc to see if they also exist there. If they do, either link or overwrite them with the latest versions. And ensure that there aren't any old library versions around. libasound usually resides in /usr/lib, but I have seen it in /lib. Is the linked version the version from your compile?

The script is found at http://www.alsa-project.org/alsa-info.sh You can run the script so the results occur locally, by specifying the ---no-upload option. alsa-info.sh --no-upload You would then paste the output into your email instead of providing a link. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
