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 |

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:
... Dec 3 22:37:30 cheren kernel: [17180407.836000] em28xx #0: found i2c device @ 0xa0 [eeprom] Dec 3 22:37:30 cheren kernel: [17180407.840000] em28xx #0: found i2c device @ 0xb8 [tvp5150a] Dec 3 22:37:30 cheren kernel: [17180407.840000] em28xx #0: found i2c device @ 0xc2 [tuner (analog)] ...

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.
