clicking measure produces an error at the end of its run

observed the following error:

hmm - just wondering - is the Makefile still correct after the directory restructuring work in the last couple of days?

good news is that I can reliably reproduce when I use my internal sound card: never did as my calibrated mic needs 48V phantom powering which only my USB interfaces can provide. Big relief it still works for my usual set-up so I did not break anything in my recent clean-ups :).

I need to dig a bit deeper tomorrow. All recent findings were definitely good to have been fixed and probably this one too.

couldn't wait :)

basically the recording calls a script:

/usr/share/rhythmbox/plugins/DRC/measure 32 44100 45 21000 5 2 hw:0,0 hw:0,0 /home/tobias/.cache/rhythmbox/DRC/MeasureResults/impOutputFile20150627230427_45_21000_5.wav 0.5 2

last parameter is the record channel. Strange that for my internal soundcard only '2' worked. After I figured that out I changed the input channel in the UI and that worked too.
Not that it would make a difference as there are no calibrated mics for internal sound cards :). But maybe still good to have a look: can you call the measure script directly and give me the output?

in my case I got an alsa error for channel one and recording just did not happen at all:

arecord: set_params:1239: Channels count non available
