Back in August, 2020, Honda issued Service Bulletin TSB 20-058 Display Audio Failure, with it's 'FIX' for the popping & crackling speakers, and no sound from audio, and network lost faults. Reviewing feedback on this forum it appears this TSB solved almost all those specific issues. That TSB was great news to those that suffered from those problems.
But for those individuals that are more 'hesitant' to have Honda Techs touch their vehicle (are you reading this ProdGirl?), not even to complete the Passport recall [TSB 20-047] now may be a good time to address any Display Audio problems, or do it just in case. The 'old' [TSB 20-058 for Display Audio Failure] bulletin is still in effect, but Honda just released new TSB 21-012 that offers to not only repair the issue, but Honda is now extending their warranty for those parts/repair to 5 years or 60,000 miles (original TSB had no warranty).
[Edit] - This new warranty extension bulletin is effective on audio repairs completed after February 18, 2021. Don't know if Honda will issue some other form of warranty letter for those that had same work completed previously on TSB 20-058. I had dealership complete this TSB on mine (though I didn't actually have ANY problems or symptoms) just for the extended warranty, in case something comes up later.
