PC 2.0 acting strange

[Xene]

So I wired up my bored (after lots of questioning) and did a test fire up tonight while it wanst in the saber and a really strange thing happened, the main LED and illuminated switches worked great, but the saber appeared silent, upon deactivation, i heard the faintest sound, so I rebooted it and sure enough if I listen carefull I can make out the activation blaster bolts and deactivation, im guessing the hum and boot sounds are too quiet for me to hear. I went and checked the SD card and the volume was at max~has anyone else had a simular problem? for the record I did do a bit of searching on this subject but couldnt find anything~please help?!

try switching the lead for your speaker around.

Speaker polarity doesn't matter. Do you have another speaker to try?

speaker might be the problem or do you have a fresh charge on the batteries

Here's hoping it's the speaker, but...did you through-hole solder the speaker leads? I remember some PC-using members having had trouble with the speaker leads shorting against the SD card holder. It could also be ESD damage to the board. ESD is unpredictable; it's not hard to believe that a static shock could burn out just the audio driver. You could also check your speaker connections. A loose or poorly formed connection could be the cause.

One last thing to check is something that I ran into on my first saber: Check that the speaker-side connections aren't touching the speaker housing. It's difficult for me to explain without pictures, but if the wires are soldered flat against the speaker terminals, a little bit of extra wire sometimes hangs over. If this extra wire contacts the speaker's metal body, it can short. Fortunately this problem didn't fry any components, but it did cause the speaker to cut out.

Possible, but not probable. ESD damage is more of a danger at the component level. Complete PCBs are more likely to be damaged by improper connections, over-voltages, etc.

Certainly check the speaker solder points as they are very easy to short-out on the body. You can (if you disconnect the existing speaker), try out another speaker with some alligator clips (e.g.: computer speakers). It should be plenty loud without any further amplification.
