Comment 32 for bug 1256511

module-switch-on-port-available should not automatically change the card profile from analog to hdmi, and when you switch the profile with pavucontrol, that choice should be remembered... I'd like to see PulseAudio logs.

Could you do this:

1) Disable autospawning:
        echo autospawn = no >> ~/.config/pulse/client.conf

2) Stop pulseaudio:
        killall pulseaudio

3) Start pulseaudio in a terminal:
        pulseaudio -vvv

4) Set the card profile:
        pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo

5) Stop pulseaudio with Ctrl-C and save the log output.

6) Start pulseaudio again:
        pulseaudio -vvv

7) Check the active card profile:
        pactl list cards

8) Stop pulseaudio with Ctrl-C and save the log output.

9) Attach the logs from steps 5 and 8 and the pactl output from step 7 to this bug.
