Picroft detects wake up word, but not question

Picroft on Raspberry B+, with vanilla USB microphone.

Detects the wakeup word, but fails to decode the question.

Typing question gets the answer (What’s the time?)

Didn’t get a good listen to you, it seems.
Does it correctly hear you ever?

It never has responded, apart for the wake word. I did the arecord and aplay test and the “default” level for the microphone was clearly very quiet (I could barely hear it in the playback). Is there a way to move up the microphone sensitivity?

aha- found “alsamixer” and put the mic sensitivity up and things are working now!!
