</div>just to explain what the changes actually do:<br>
<br>
the wm8775 in v4l-dvb has a fixed gain which uses a form of AGC<br>
circuit to center to gain someplace above 0dB. this function is<br>
fixed.<br>
<br>
my changes to not activate that feature and by defailt the gain<br>
is set to 0dB.<br>

<br>
</div>sort of yes. before and after I could get distortion in some<br>
audio passages, however, by utilising v4l2-ctl to set the gain<br>
to -6dB those passages become clear. this will be input<br>
dependant. I don't really have a lot of test cases to provide<br>
you with and haven't done much investigation into the optimum<br>
setting.<br>
<br>
you can test this more easily using the newly working FM<br>
radio (does it work in the hvr-3000) in kradio which has<br>
a radio volume control.<br>
