So when I do:

modprobe em28xx device_mode=1 i2c_scan=1

I get:

...
Dec  3 22:29:59 cheren kernel: [17179957.448000] em28xx #0: found i2c device @ 0x1c [???]
Dec  3 22:29:59 cheren kernel: [17179957.472000] em28xx #0: found i2c device @ 0xa0 [eeprom]
Dec  3 22:29:59 cheren kernel: [17179957.476000] em28xx #0: found i2c device @ 0xc2 [tuner (analog)]
...

What is at 0x1c? Would this be the DVB demodulator? In analog mode I get:

...

yes it's the ATSC demod in your case. Only one chip can be visible at a time so first we focussed on NTSC, next step os ATSC.

Notes on audio

Audio has a clicking sound every 256ms(I measured it) with varying amplitude. I just did this to get a sample:

sox -r 48000 -w -c 2 -t ossdsp /dev/dsp1 -t wav /tmp/test.wav

Sample here: [[1]]
