Description Dan Evans 2009-03-10 15:35:56 UTC

When performing a factory reset-- either via menu, or holding the reset button-- there's a loud pop on the connected speakers.

Dan: this is on the headphone jack, right?  If so, it's a known issue.

Comment 2 Dan Evans 2009-03-11 08:48:10 UTC

Good point.  I didn't specify, but you're right.  At that time I was connected via the headphone jack to my speakers.

Comment 3 Blackketter Dean 2009-03-11 16:40:23 UTC

The next build should have a fix for this problem.

Comment 4 Blackketter Dean 2009-03-25 14:19:12 UTC

Richard's working on minimizing the boot pops now.

Comment 5 Richard Titmuss 2009-03-26 05:19:07 UTC

Pops on boot have been fixed, but I think the headphone jack is a h/w problem.

Comment 6 Blackketter Dean 2009-03-31 17:56:21 UTC

Maurice is fixing for the MP build

Comment 7 Dan Evans 2009-04-01 09:14:10 UTC

Wait, we won't know if this hardware issue is fixed until the product is going out the door to customers?  We won't know for PB3 or MPQ?

Comment 8 Blackketter Dean 2009-04-01 10:32:33 UTC

We'll know from unit testing the change before it gets released to hardware. 

Also looking at ways to address this via software and rework for pre-MP hardware.
