F9 & F10-Snap1 pulseaudio and underlying mixer channels

I'm testing F10-Snap1, and I noticed that music was playing rather
softly, even though I had the application volume and the master
pulseaudio volume turned all the way up. I ended up doing this:
1. mv /etc/alsa/pulse-default.conf /tmp
2. alsamixer
3. PCM was at 60% or so. Turn it up all the way.
4. mv /tmp/pulse-default.conf /etc/alsa
Now I could hear my music.
I've seen a similar issue with F9 on this same laptop where no sound
comes out at all until fiddling with the underlying ALSA channels. I
think this only happened after resume from hibernate, but I don't
remember now.
Is this just a bug, or a design problem with pulseaudio hiding
underlying mixer channels? How would one expect to set the hardware
mixer channels when pulseaudio hides them from the user?
