[solved] usb speaker not working on squeeze 6.01

[wuming]

Hi I am new to Debian,
My audio is working, but when i put my usb speaker in it, it doesnt redirect sound to the speaker, just continues to play from the laptop.

In gnome, System->Prefernence->Sound shows the following:
Device: HDA ATI SB
Device: Logitech USB speaker (Alsa Mixer)

lsusb shows:
Bus 002 Device 003: ID 046d:0a04 Logitech, Inc. V20 portable speakers (USB powered)

dmesg shows:

my usb speaker has volume control-up/down, mute, that seems to work, just no sound coming out of it.
I am running Squeeze 6.01, kernel 2.6.32-5-686
Also I have 2 computers with squeeze 6.01 installed, both doesnt output usb sound, but the speaker works fine with winXp and ubuntu.

any help is much appreciated
thanks.

solved. solution was:
cat /proc/asound/cards, showed [1] as the speaker, then added .asoundrc to my home directory
------------
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
--------

[neilcpp]

Thank you for this - it worked for me as well, but just to remind everyone - for the .asoundrc to take effect, you must log out and then log back in again. At least, that is what I had to do - but many thanks anyway.
