I did a bisect which implicated f2bd1c5ae2cb0cf9525c9bffc0038c12dd7e1338 as the first bad commit. Reverting this commit on 6.1.8 gives me working sound again. I'm not clear why this is breaking 6.1.x since it appears to be in 6.0.18 (7494e2e6c55e), which was the last working package in Fedora for the 6.0 line. Maybe something else didn't make it into 6.1?
