Hi Alexander,

While trying to get understandig of the verbose boot messages of
snd_hda(4), I found the following which seems to match the problem (only recording
from Jack):

hdac0:  nid 18 0x99a30930 as  3 seq  0           Mic Fixed jack  3 loc 25 color Unknown misc 9
...
hdac0:  nid 24 0x03a19820 as  2 seq  0           Mic  Jack jack  1 loc 3 color    Pink misc 8

i.e. the nid's are 18 (internal mic) and 24 (Jack);

But in the DUMPING's Playback/Record Paths the nid=18 and nid=24 look
different:

24:

pcm0: Record:
pcm0:
pcm0:     nid=8 [audio input]
pcm0:       |
pcm0:       + <- nid=35 [audio mixer] [src: mic, mix]
pcm0:              |
pcm0:              + <- nid=24 [pin: Mic (Pink Jack)] [src: mic]
pcm0:              + <- nid=11 [audio mixer] [src: mix]
pcm0:
pcm0: Input Mix:
pcm0:
pcm0:     nid=11 [audio mixer]
pcm0:       |
pcm0:       + <- nid=24 [pin: Mic (Pink Jack)] [src: mic]


18:

pcm1: Record:
pcm1:
pcm1:     nid=9 [audio input]
pcm1:       |
pcm1:       + <- nid=34 [audio mixer] [src: monitor]
pcm1:              |
pcm1:              + <- nid=18 [pin: Mic (Fixed)] [src: monitor]

(there is no 'Input Mix:' section part for nid=18)

Can this cause the problem?

What else could I debug to nail this down?

Thanks

	matthias
