 I don't have the hardware available, so I can't reproduce this problem 
 any more. I am forwarding some old follow-ups on freebsd-multimedia, so 
 that they are noted in GNATS.

 Did recording ever work on your M5451?
 I have no idea why t4dwave(4) still uses legacy capturing mode(Sound
 Blaster compatible mode). It seems that M5451 support code lacks codec
 initialization. So I guess its ADC part was not activated.
 Try attached patch and let me know the result.
