eld_valid 0
monitor_present 0
eld_valid 0
monitor_present 0
eld_valid 0



it is possible that the advice concerning these is due on the "monitor_present 0 eld_version 0"?

I tried to use
# speaker-test -Dplughw:1,3 /usr/share/audio/complete.wav

and
# speaker-test -Dplughw:1,7 /usr/share/audio/complete.wav

and
# speaker-test -Dplughw:1,9 /usr/share/audio/complete.wav

but it doesn't works


My hardware is Asus EEBOX model 1012P
Thanks to all in advance

U need user-space alsa drivers 1.0.24 or later. Type this command and see if anything is missing here or not..... cat /proc/asound/pcm
