That's a flaw in the DR-135... the speaker picks up crosstalk from the
digital input. The easiest way to avoid it is to put a plug in the
speaker jack and mute the whole thing.

Yeah, that's not a good sign. Could be a small fracture in one of the
traces. I've caught one of those in testing and never was able to
figure out where the problem was. Even under a microscope it can be
hard to spot the flaw, especially if it's where a trace connects to a
via. And the bad part is that it can pass all of the testing just fine,
and then fail as soon as you flex it a bit to stick it down to the
velcro. You can sent it in and I'll check it out, and if I can't find
the flaw I'll just send you a new one.
Sorry for the trouble...
