Hello Devin,
I did as you suggested. Unplugged the stick reboot and plug it again.
And just to be sure I did it two times. Now the device works, but it is
unable to change channel. That is to say, when I use the command "vlc
channels.conf" it tunes to the first station in the channel file and
can't change it. Other apps (xine, kaffeine) that seems to change to
the latest channel don't work at all. The dmesg output after plugging
the driver is in attach. In dmesg I noticed lines like this 

[drm] TV-14: set mode NTSC 480i 0

I suppose this hasn't anything to do with the analog audio problem, but
just to be sure I ask you. Also, using arecord/aplay for analog audio I
get an "underrun" error message

arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay -
Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 32000 Hz,
Stereo Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 32000
Hz, Stereo underrun!!! (at least -1255527098942.108 ms long)

Cheers.
