Specifying a device for sox output.

[peter@easthope.ca]

This system has three snd devices.   
peter@dalton:~$ ls /dev/snd/by-id/*
/dev/snd/by-id/usb-046d_0807_C9748B60-02
/dev/snd/by-id/usb-0d8c_C-Media_USB_Audio_Device-00
/dev/snd/by-id/usb-0d8c_C-Media_USB_Headphone_Set-00
peter@dalton:~$ ls /dev/snd/by-path/*
/dev/snd/by-path/pci-0000:00:03.0-usb-0:2:1.0
/dev/snd/by-path/pci-0000:00:03.2-usb-0:1:1.0
/dev/snd/by-path/pci-0000:00:03.2-usb-0:2:1.2

The two C-Media devices should be able to accept sox output.
How should one of them be specified?  If ekiga is running, 
is contention possible?  If so, is there a way to resolve it.

Thanks,       ... Peter E.
