Sure.

1) Don't redirect alsa to pulseaudio.
For that, in case you have in /etc/sound.conf these two lines:
pcm.default pulse
ctl.default pulse
Commment them out, like this:
#pcm.default pulse
#ctl.default pulse

2) Politely ask pulseaudio to share the mixer with its siblings.
For that, include i /etc/pulse/default.pa these two lines:
load-module module-alsa-sink device=dmix
load-module module-alsa-source device=dsnoop
And comment out conflicting settings, case occurring.

Also, with these settings both alsamixer and pavucontrol can then be used.
