It is a pixelview. line in input it is the only way, since the onboard card
does not have an auxiliary input for using a CD audio cable.

In myth-setup (not mythfrontend) it does not accept ALSA:default
If I force it (clear and type) the value is lost when I return.

In this part (mythfronend general) I was already using ALSA:default. This
one holds when I force it.

This is the problem. There is no line in volume. It is a known issue with
this Intel onboard card (Sigmatel) and alsa.


"The integrated hda sound works but doesn't let you do a loopback from line
in to line out with current alsa drivers." (
