No Audio/Slow Operation?

I sent this to support@empeg a couple days ago; haven't had a response yet, so I figure I'd get some of ya'lls opinions.

I did play around with the options a bit, to make sure the cell phone mute wasn't a problem, which it wasn't (it's set to Never mute).

-------------------

Hey guys,

Last night I finally got around to upgrading to 1.02 developer. I kept
forgetting to bring the player back to the car, and when I did this
afternoon, I noticed that there was no audio being put forth from the
unit. Everything else was ok, the boot, the upgrade, and so on.

I did notice that when trying to change the volume when the empeg was in
the Jeep, it went VERY VERY slow... if I held down the left arrow for like
3 seconds, it would very slowly drop all the way to - infinity (mute).
And the player even locked up after tinkering with it a little while.

I tried powering it up from home, it booted fine.. but again, no output
from the audio outs.

Here is a dump from the boot:

I wanted to send you this before I tinkered with it anymore (going back to
1.01, etc, to see if you have any idea what the problem is.

-----------------------------

Any ideas guys?

(O|||||O)

Interesting. Looks like a really odd hardware problem to me. I'm surprised you haven't gotten a reply from support yet.

Have you tried reloading the 1.02 developer image yet?

That's not a bug, it's a feature. You triggered the slow motion audio easter egg. *wink* There's another trick in there to induce chipmunk mode. *wink* *wink*

Your email is flagged as having been replied to or forwarded - if you haven't heard anything then I guess it was the latter, and is awaiting a more techie opinion. The support guys should really tell you when they do that - sorry!

Rob

Whoops. I thought I sent it Wednsday. My bad. :)

Anyway, I got a response this afternoon.. It sounds like it might be a bad DSP (what would cause that spontaneously anyway?)

I still have yet to try to install 1.01 and see if it "fixes" the problem.

I'll keep ya'll posted.

(O|||||O)

Well, there's either something wrong with the I2C drivers or with the DSP itself (crystal gone bad, maybe). We had a couple of mk1s fail in this way, but I don't think I've ever seen a mk2 suffer like this before.

If it has to come back I'll fix it quickly :)

Hugo

Yeah, it looks like that's the problem. I tried going back to 1.01 Consumer then Developer and still had the same problem.

I've been in contact with support@, I should be getting faxed an invoice so I can return it to ya'll.

Thanks!

(O|||||O)

Just got my emma back, everything looks (and sounds) great.

I even got a new empeg box and no-slip knob too! Can't beat that with a stick!

Thanks!

(O|||||O)

What is the difference between a no-slip knob and a regular knob (no bad jokes please!) ??
Does it have some rubber sleeve around it?

Thanks

The "fins" which hold the knob to the shaft are thicker and shaped differently. It's essentially a tighter fit.

When I got my replacement knob, it also came with a small rubber washer. However, I didn't know what to do with the washer and it didn't seem to be necessary. So I left it off. The new knob works great.

So there is no fundamental change to the front or the "User manipulates this side of the knob" ??? (OK, make jokes)

Thanks

No, no changes to the front or anything. You have no way of knowing it's the new knob unless you pop it off and look inside the shaft.

Damn, it's hard NOT to make jokes...

*laugh*
Tony said "shaft" !!!

OK, fair enough, I guess I will have to wait for v1.1 for the volume knob polling update, I hate turning the knob twelve times to turn the volume down when leaving the car.
Or I could bastardize an old Mechanix or Construx rubber wheel to allow for a larger diameter turning point, with less finger slip on the knob, because we all want a fim grip on our knobs. (OK, that was a little too much, but I couldnt help it!)

How about one of them 10 lb. knobs from the stereos of yesteryear. One quick hard turn and they spin a dozen times.

Glenn

RTFM

The rubber part fits inside the knob - I'm surprised it works without it. It does make it quite difficult to fit, though, so if you're getting good results then go with it.

By the way, I have a bunch of new knobs with me for the meet - if you want a good knob at the meet, I'm the guy to see. OK, I'll stop now.

Rob

Heh, I guess I'll save the rubber, then.

Okay, okay, enough knob jokes.

What knob jokes? Did I miss something???
