Well , i have a doubt , i have 2 cards and i`d like to know if
-channels 6 really enables surround when i pass -ao
alsa:device=default=1...


I was taking a look at mplayer output and i see:

to card 0 [default]

# mplayer -v VIDEO.avi
alsa-init: requested format: 48000 Hz, 2 channels, 9
alsa-init: using ALSA 1.0.14a
alsa-init: setup for 1/2 channel(s)
alsa-init: using device default


# mplayer -v VIDEO.avi --channels 6
alsa-init: requested format: 48000 Hz, 6 channels, 9
alsa-init: using ALSA 1.0.14a
alsa-init: device set to surround51
alsa-init: using device surround51


Clearly it is using surround on the first card when i pass the
--channels 6 , but when i select the second card...

# mplayer -ao alsa:device=default=1 -v VIDEO.avi
alsa-init: requested format: 48000 Hz, 2 channels, 9
alsa-init: using ALSA 1.0.14a
alsa-init: setup for 1/2 channel(s)
alsa-init: using device default:1

# mplayer -ao alsa:device=default=1 -v VIDEO.avi -channels 6
alsa-init: requested format: 48000 Hz, 6 channels, 9
alsa-init: using ALSA 1.0.14a
alsa-init: device set to surround51
alsa-init: using device default:1


i can see the device being set to surround51 , but just below i seed
using device default:1 ... Is it really using surround ? The source
video is really 5.1 !
