Grrreat. I found the "priority" values in {analog-input-mic.conf, 
analog-input-internal-mic-always.conf, analog-input-internal-mic.conf}, 
and switched the "87" and "89" values. Now pacmd-list-sources shows 
priorities that suit me:
     analog-input-microphone-internal: *Internal Microphone* (priority 
*8700* , available: *unknown* )
     analog-input-microphone: *Microphone* (priority *8900* , available: 
*no* )

However, even though the priorities look fine, the behavior at startup 
is still the same: "Internal Microphone" is still preferred to "Microphone".
     --> Could it be due to the fact that "Microphone" is flagged 
"available: no"?
     --> If yes, how can I work around this? If no, any other idea? Any 
solution putting "Microphone" first will do, I don't care the least 
about "Internal Microphone".

Thanks for the help!
