Whilst I too, have a love-hate relationship with PulseAudio, I think we 
can do better support than simply `grep -qiF pulseaudio && echo "disable 
or remove pulseaudio"`.

With the exception of Bluetooth audio devices (which this is not), 
PulseAudio appears to use ALSA as its "back-end" to talk to local audio 
hardware.

Unless those messages are generated by `pulseaudio.ko` I think we can 
safely conclude these are in fact, ALSA kernel driver messages.
