alsa mplayer

ALSA stuff.

Avoid OSS, as it seems the hardware gets locked during use.

aplay -l

to list the playback devices connected. There will be card numbers,
devices and subdevices.

mplayer addresses them as,

mplayer *.mp3 -ao alsa:device=hw=0.1

where this addresses card zero, device 1. At least, I think so.



alsamixer -c 2

will allow device 2 to be adjusted

==============================

At work:

mplayer -ao alsa:device=plughw=1.0 *.mp3

works, playing back from the usb DAC. :)

================================

Now, configure the mixer (mplayer level control) to effect the second device rather than internal.


.mplayer/config

#ao=alsa:device=hw=1
#mixer=/dev/mixer1
