Dear:
I am using a tv card which has a standard usb audio interface,
when I plug the card, snd-usb-audio finds my usb audio interface,
And I use mplayer to test the effect, unluckly, I could not get and sound.
And I give mplayer these parameters:
""" mplayer alsa:adevice=hw.1
,0:volume=100:immediatemode=0:amode=1:audiorate=48000:forc
eaudio
"""
I am getting so frustrated by this problem.
I don't know how to let USB Audio driver to drive my audio interface.
Please help me.

What exactly happens? Do you get silence, or does mplayer abort?
Is it possible to record something from the device with arecord?
Regards,

It's possible that the device needs some special configuration to select
what is to be recorded from the audio interface.
Please show the output of "lsusb -v" for this device.

Clemens
