Agreed.  First confirm that it truly is broken by trying it with another
device *and* cable that are known to work.

I see that it has a line-level 3.5 mm jack.  I would definitely try
feeding it an analog audio signal through this jack.  Alternatively, you
could try the audio RCA jacks.  This should tell you whether the audio
amp itself is broken, or whether the problem lies somewhere upstream.

Not to insult you, but you should also confirm it's not muted.  Even if
the on-screen display doesn't indicate it, I'd toggle the mute button a
few times.  Finally, I also suggest disconnecting power for a minute or
so and then reconnecting.  Perhaps the firmware has just gotten confused.

Beyond this, I think you're getting into oscilloscope territory.
