On non-seamless migration, this is not an issue. Playback will be stopped and restarted.

On seamless migration, the migration session is different from the main session. The audio manager is only watching channels in the main session: channel-reset or destroy is not reached in this session during migration. I have tried to verify this locally with a simple test while playing music, unfortunately, qemu takes forever to migrate (remaining ram fluctuates between 8mb and 20mb).
