There are a few variables which control how PulseAudio controls the volume. You can either edit /etc/pulse/default.pa (you'll have to be root to do that) to change the behavior for all users, or copy that file to ~/.pulse/default.pa and then edit that file, to change behavior for the current user only.

Open the file mentioned above. Find the row saying "load-module module-udev-detect" and change it to:

load-module module-udev-detect ignore_dB=1

To try your changes, restart PulseAudio with the following command:

killall pulseaudio

PulseAudio will then autospawn (restart itself).

You may find that the above workaround is insufficient, in which case you may configure PulseAudio to control only one mixer control, e.g., PCM (cf. alsamixer Find the row saying "#load-module module-alsa-sink" and change it to:

load-module module-alsa-sink control=PCM

(remember to remove the # in the beginning of the row!) Optionally replace PCM with the mixer control you want PulseAudio to control.

You will then need to killall pulseaudio as above and allow the daemon to autospawn.
