Only you must be carrrefuly if you have on your system .asoundrc which is not compatible with a new version of alsa but if you have a new linux installation then will be OK. For playing you need alsa clients or for oss client you can install alsa-oss on debian for example. Then you can play with command: aoss playcommand FILE .
