The ignore_suspend settings were added in an attempt to try and fix

Do these systems not have the ability to continue to play audio through
suspend using the DSP? That's the sort of thing that ignore_suspend is
normally used for.
In theory yes, in practice if we keep ignore_suspend set then we get
audio for a couple of more seconds after suspend until the buffers
are empty, as we have no code keeping them filled, which is not really
useful, since we don't support this in a meaningful way it is better
to just do a normal full suspend.
That sounds like what's missing is hookup of whatever the DSP uses to
wake the system when it's getting to the bottom of the buffer? That's
the normal way this stuff is implemented anyway.
