I got mine to update by unplugging it for 1 min and plugging it back in. All cases that caused the crackle are resolved in my case. I still have concerns over Bose's lack of backout plan in the event of an issue and inability to opt out of firmware updates. If I could, I would have returned this device so, this behavior will affect my future buying decisions. I'll look into rigging my firewall to control updating in the future now that it is working.

Still no communication if Firmware 4.0.8 has potentially damaged the systems .... (soundbar or sourround) with this cracking on speakers.
And if so the procedure to exchange and get repaired
Lack of full communication and professionalism answer on this kind of subject due to the contention of Bose as premium sounc company
