I can confirm it in U12.04.

I have solved it this way:

------------------------------------------------------------------
/etc/pm/sleep.d/90_usbaudio :

#! /bin/sh

case $1 in
     suspend|suspend_hybrid|hibernate)
              true
        ;;
     resume|thaw)
              sleep 1; sudo -u inet /home/inet/prog/usbaudio.sh
        ;;
esac
---------------------------------------------------------------------
 /home/inet/prog/usbaudio.sh :

#!/bin/bash

# After resume from SUSPEND is USB sound card muted and not default ->

pacmd set-default-sink alsa_output.usb-0d8c_C-Media_USB_Headphone_Set-00-Set.analog-stereo
pacmd set-default-source alsa_input.usb-0d8c_C-Media_USB_Headphone_Set-00-Set.analog-mono
pacmd set-sink-mute alsa_output.usb-0d8c_C-Media_USB_Headphone_Set-00-Set.analog-stereo 0
pacmd set-source-mute alsa_input.usb-0d8c_C-Media_USB_Headphone_Set-00-Set.analog-mono 0

---------------------------------------------------------------------

It works for me. You must modify sink/source names of course. Do not use indexes - use names!

Note: user "inet" is the only one possible

Hope it helps you :-)
