Slackware :: How To Select Usb Speakers

I have picked up a pair of usb speakers for my laptop that are detected as:

Code:

andrew@skamandros~$ cat /proc/asound/modules
0 snd_hda_intel
1 snd_usb_audio

and:

Code:

andrew@skamandros~$ dmesg | grep -i logitech
usb 3-2: Manufacturer: Logitech
usb 5-1: Product: Logitech USB Speaker

[code]....

but even when I configure the usb speakers with:

Code:

alsamixer -c 1

the speakers do not roar to life . I suspect I am missing something basic here and I would dearly like to be able to switch easily between the hda intel and the logitech usb speakers...
