Hello Peng! Well the part of .asoundrc I posted should work for your card. I have a delta 1010LT, but regarding JACK it's not so complicated. the only thing you need to do, to make this configuration work is installing JACK. The JACK Audio Connection Kit. It should be shipped with all Linux distributions nowadays. If you have installed JACK, but it doesn't start au5tomatically, you can go to an empy terminal (or open an xterm) and type something like: jackd -R -d alsa -d hw:0 -r 44100 -r 44100 marks the sampling rate you wish to have. If jack is started, the configuration is in place and you run something like: aplay file.wav should play sound. Make sure that file.wav has the same samplingrate as the one given to jack. So any WAV-file ripped from a CD should be fine. If your mplayer is configured to use ALSA, you should be able to just run: mplayer audio_or_video_file or of course: gmplayer audio_or_video_file I hope that can help you along a bit more.
