With the 7.0.0-31-generic from resolute-proposed, the speaker and mic works
fine.
1. With 'Test Speakers', I confirmed it produces crisp, loudly scaled audio at
a standard volume level (30–50%).
2. With 'arecord -f cd a.wav and aplay a.wav', the Microphone Capture
function works fine.
3 Mic LED with F4 works fine.
