Select the S-Video input (--set-input=1), then try the other possible
audio input:
v4l2-ctl --set-audio-output=2
Perhaps the PVR-150lp is wired differently for the audio line-in.
If that didn't work, then you can also try to edit the ivtv-cards.c
source from the kernel: go to the ivtv_card_pvr150 struct and modify
the WM8775_AINX value in the audio_inputs section for the
IVTV_CARD_INPUT_LINE_IN1 input. Currently it is WM8775_AIN2, but you
can try all four values (AIN1 - AIN4). If you have different wiring
then one of these values should give you audio.
If not, then you have to consider testing it under Windows in case the
card is broken.
