Suspend mode reset my configuration to internal microphone instead of keeping usb microphone as default.

I always have to manually change it back in the sounds parameters.

Reboot is ok : keeps the usb microphone as default.

Please help.

This fixed my problem :

A)

1) create a file /etc/pm/power.d/10_alsa-restart
2) edit the file add the following
#!/bin/sh
/sbin/alsa force-reload
3) save the file and make it executable.

B)

Also, in the file "etc/modprobe.d/alsa-base.conf", I add :

options snd-hda-intel=1
options snd-usb-audio=0

and comment all options lines after "# Prevent abnormal drivers from grabbing index 0"

I found the name of devices and index with :

cat /proc/asound/modules

C)

Also, in the file "etc/pulse/default.pa", I add (uncomment last line and replace "source" by the name of my device) :

set-default-source alsa_input.usb-046d_0821_3961BAE0-00-U0x46d0x821.iec958-stereo

I found the name of my device with :

pacmd list-sources
