Hi all
Here is how I managed to reproduce this assert failure, twice.

1. Ensure you are running PulseAudio git master, and pavucontrol git master.
2. Make sure you have the below asound configuration somewhere for pulse to be able to find, so it can use a52:#.
3. Get pulseaudio running, and load pavucontrol. Go to the profiles tab, and attempt to select the digital surround 5.1 + analog stereo input profile. Pavucontrol should complain that the connection to the server was lost.

I have yet to try the surround 5.1 output with no input choice. Here is the asoundrc sample:

# Description: This will make it possible to use a52 with PulseAudio out of
#              the box. It may be useful for other use cases. Just include
#              this in your ~/.asoundrc .

pcm.a52 {
    @args [ CARD ]
    @args.CARD {
               type string
               default 0
    }
    type plug
    slave {
           pcm {
               type a52
               card $CARD
           }
    }
}

# Usage: aplay -D a52:0 /foo.wavvvvvvvvvvvvvvvvvvvvvvvvvvv
