Levone1 did run the command with the correct container name afterwards. I also posted that and then deleted my message when I noticed.

Regarding sound, I can only say that it works for me and others on Pro¹, and I believe it works on X Compact too (not tested, my X Compact died), so maybe you can find something interesting in the the Pro¹ port Git repository?

We'd need Illyria to confirm that sound worked on his X Compact too, because that's an official SFOS release, not a port, and it's surprising that it would not work on XA2 then.
