To see all of the named devices that alsa knows about use aplay -lLv. Also try aplay -D hwplug:0,0 some.wav. If it plays, alsa is working, you have an incompatibility in your configuration. This can usually be fixed by altering the asound.state or adding an .asoundrc in your home directory. If this is the case, you can search online, or ask here. I probably won't be able to help as I am just learning this myself. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
