There aren’t many command line options in beebem it seems. Nothing for sound. I’m building an older version now just to see what happens. All in all, beebem is working ok for me, except the sound issue.
If all else fails I could probably start it with a script and simply play some mp3s in the background lol. It wasn’t important that I had a BBC emulator, tbh, I just wanted the challenge of running an emulator few have working.
