Read from recorded file works, but directly from mic doesn't

[leledumbo]

I'm testing the Quick Run (implicitly using jconf written there), for my own file I use the following to record:

$ parecord --rate=16000 --channels=1 test.wav

then change test.dbl content accordingly, replacing mozilla.wav with test.wav. This works fine and julius recognize at least many of the words. However, when using mic directly using this config:

-input pulseaudio
-htkconf wav_config
-h ENVR-v5.3.am
-hlist ENVR-v5.3.phn
-d ENVR-v5.3.lm
-v ENVR-v5.3.dct
-b 4000
-lmp 12 -6
-lmp2 12 -6
-fallback1pass
-multipath
-iwsp
-iwcd1 max
-spmodel sp
-no_ccd
-sepnum 150
-b2 360
-n 40
-s 2000
-m 8000
-lookuprange 5
-sb 80
-forcedict

julius cannot recognize any of the words I say, it always ends with <input rejected by power>. My guess would be pulseaudio mic as initiated by julius doesn't use 16KHz sampling rate and mono channel like above, but I can't find any option to pass it to the pulseaudio.

Diff-ing the two jconf-s, there's only so little differences:

                   input source = waveform file               |                    input source = microphone
                  input filelist = test.dbl                   |             device API          = pulseaudio
                  sampling freq. = 16000 Hz required          |                   sampling freq. = 16000 Hz
                 threaded A/D-in = supported, off             |                  threaded A/D-in = supported, on

Your message 'input rejected by power' suggests that your microphone audio level gain is too low. Try using 'SkryBot Domowy' from SourceForge to tune your microphone to proper levels.

Dang, I somehow missed your reply, apologize for that.

That's weird as my microphone volume is maxed out and parecord confirms that, but I'll still try your suggestion.

EDIT: Cannot proceed, "SkryBot Domowy" is Windows only as I'm on Linux.

Having the same trouble. Tried a few things without success. Verified with adintool that Julius is hearing my microphone at normal levels, so the power level error is puzzling.
