Bugzilla – Bug 12783
Audio cuts off after power cycle

we think it's in the microprocessor, and it will only be a problem on PB1/2 units Caleb will update the MSP so it works for all models. the MSP has the ability to force mute the PA on the older boards, but does not have that ability on the new boards.
Checked in to rev r6512 of squeezeos, r6234 of hardware. FORCE_MUTE on PA1/PA2 is the same pin as IR_SENSOR_POWER on PA5. I use IR_SENSOR_POWER to detect whether we're installed on a PA5 or earlier board, but forgot to turn the pin back into an input on earlier boards.
Fixed in build 6514, from the 6512 checkins.
Still a problem with PB1/PB2
Eeew. This is a nastier problem than I thought. Good news is: I know what's wrong, and it won't affect MPQ. Bad news is it may take a day or two to fix for earlier boards. We can fix pretty easily by creating 2 different MSP loads for different HW platforms. I'll see what I can do for the short term.
Fixed in r6521 with a temporary workaround of using a different MSP load per board. This isn't the solution I'd like generally, but works for now.
