Question About AMD USB issues

[Ararauna]

I have the USB drop out issue, and have a few questions. I have a MSI A520M pro board with ryzen 5 4650g and the latest update is 2021-03-15.

1. Mostly I've seen X and B boards mentioned, might A boards also get an update for that and I should wait for it, or just try this one now?
2. As I understand, update has to be done with an usb, can it drop out while updating and is there a risk of permanent damage because of that?
3. Besides the USB problem, I also have an issue with headphone port, where sound appears/disappears on one or both headphone sides when rotating the jack (that's with two different headphones, and they work ok on an mp3 player) and I wonder whether it's related as there was also an issue with audio mentioned (but it's "crackling" and that I don't have)? If not, what could be the cause? It's a new pre-built pc.

Yes, should fix audio issues as well. I don't know enough about how this works to answer what happens if you have a drop out while updating. If the board is that new I'd say update, return under warranty if it fails and bricks.

Ok, thanks. Since the PCIe on this one is 3.0 and not 4.0, maybe I'll try the advice to disable C-states before that.

Not fun Disabled C-states and one time system froze completely after some hours (no keyboard commands helped), and the second time later it restarted after some time of internet browsing. What's with that? I use Ubuntu.
