As far as I'm aware, I haven't messed around with the sound set up at all in the meantime. But now, all of a sudden, every time I use any sound related application (audacity, xmms, alsamixer, aplay etc), I keep getting the error message 'PulseAudio: Unable to connect: Connection refused', and I get no sound. Until a while ago, the sound was working perfectly. I have a Acer Aspire 5810T laptop running 64-bit CentOS 6.5.
