Dear Julien:
Thank you very much for your detailed suggestions! However I triedthem but they did not work for me :(Since I am really a newbie about sound management of ALSA I can hardlyunderstand your configration, sowhat I could do was just to paste them into my .asoundrc. I am readingmanual of ALSA and I wish I can understandyour suggestion better after reading to make some modification......
Thank you very much Julien. Have a nice weekend:)
