Dear all , first of all , let me thank you all for your helps , by your help i have learned a lot about Alsa internals . Now , I have read HD Specification PDF , found info that i need to get hda-verb working This is the command that i made : ./hda-verb /dev/snd/hwC0D0 0x23 SET_BEEP_CONTROL <parameters> 0x23 is Nid , from alsa-info script set_beep_control is defined as right key in source now the one million $ question is , what sort of parameters that i need to enable ( initialize ? ) pc speaker ? there are lots of parameters that i have tried , this can range from 0 to 255 ( of course you know this ) 0 is silent 1 is the most low sound ( im pretty sure this will kill flies! ) 255 is the most bass sound so please give me some idea , i have come this far ( if its really progress ,i just happy that I'm to make ! ) -- Armin ranjbar , System Administrator ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
