I "autospan=no"ed pulseaudio and killed the daemon with pulseaudio -k. I guess this forces the system to switch to alsa, because sound seems to be fine system-wide. This procedure seems to have solved the issue, for the freezing part of the bug described above seems not to occur any longer now. By the way a problem still exists that may not be related to the pulseaudio package, because rhythmbox crashed and closed itself while I was using it, and vlc suddenly stopped playing music and I was unable to resume it by clicking on pause/play. I had to press stop and then play again, and playback started again normally. The conclusion I've come up with is thus the following: something in the media system (i don't know exactly how this stuff works, but i presume it could be something related to the X server) is causing a crash to occur while some media file is playing on my system (this happens with both video and/or audio media contents). Then the pulseaudio daemon responds badly to this failure and makes the os unstable, as discussed above in the original post of this but report.
