Can you please trim your responses. I've had issues over the years getting alsa to play. It's always a configuration problem for me. The first step is to use alsamixer and make sure nothing is muted and the volumes are maxed out (for all devices). Another seemingly obvious thing is to make sure the speakers are connected with power and, if they have on/off or volume switches, make sure they are on and the volume is up. I'm sure that's not your problem, but it is a basic step sometimes forgotten. Another thing to check is permissions of sound devices. Mine are: $ ll /dev |grep audio crw-rw---- 1 root audio 14, 12 Jul 26 19:14 adsp crw-rw---- 1 root audio 14, 4 Jul 26 19:14 audio crw-rw---- 1 root audio 14, 3 Jul 26 19:14 dsp crw-rw---- 1 root audio 14, 0 Jul 26 19:14 mixer crw-rw---- 1 root audio 14, 1 Jul 26 19:14 sequencer crw-rw---- 1 root audio 14, 8 Jul 26 19:14 sequencer2 Make sure you have permissions to write to the device. Another test to use is: aplay /usr/share/sounds/alsa/Front_Left.wav etc. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
