This could be possible. If they are dried out, then capacitance got lost. If the the oxide coating is broken, they short. Assuming that there is dark scum on the PCB around the capacitor, resp. on the rubber thingy on the bottom of the capacitor, then it's dried out. Assuming the top of the capacitor is bloated, then the capacitor is broken, too. If you can't see something, they could be broken, too. However, if you can't see that they are broken, then take their function into account. What is a capacitor used for, that could cause delayed trouble, if it's broken, instead of causing the trouble all the times? IIUC you hear the crackling only, if there is an audio signal, there's no crackling, without an audio signal. If the crackling happens, does show top something unusual? Maybe upowerd or something else turns nasty? What happens if you don't use two sound servers at the same time? Have you tested Firefox using plain ALSA, while neither pulseaudio, nor jackd are running?
