I installed the snapshot, rebooted, plugged in both a CD player into
the line in and an external mic, launched

   (arecord | aplay) &

and then started playing with the alsamixer controls.

I can confirm that pluggin in headphones mute all the speakers. Also
the LFE level controls the bass speaker correctly.

I played with the "Capture" / "Input Source" pair of controls, and can
confirm that "Internal Mic", "External Mic" and "Line In" work ok. I'm
not sure about how to test the "CD" and "Input Mix" options.

I couldn't do anything about "Capture 1" / "Input Source 1". Has it
anything to do with the second capture device I get from arecord -l?


skandalfo at rimmer:~$ arecord -l

I tried to perform the same tests with arecord -Dhw:0,2 but it
complained about no appropriate sample format, so I suppose I was
trying something stupid.


In any case, congratulations, and lots of thanks for your good work.
My laptop now sounds much better :-D


Best regards,

   Juan Jesus.
