ALSA issue: stuttering audio on pause (mplayer, audacious, et al.)

Hi

I have the following problem with ALSA on my laptop: When I try to pause a video or an audio file in mplayer or audacious, both mplayer and audacious begin to stutter and repeat the last bit (probably the last sample) over and over again. The same happens in firefox, when I try to close a tab (or window) which plays some audio (both html5 and flash).
Firefox and mplayer do not give me any information on the command line, but audacious reports:

alsa.c:356 [alsa_open_audio]: Opening PCM device default for S16_LE, 2 channels, 44100 Hz.
alsa.c:391 [alsa_open_audio]: Buffer: hardware 255 ms, software 250 ms, period 21 ms.

I'm only using ALSA for audio playback, not pulseaudio or any other soundserver, so I guess that the problem is probably due to some misconfiguration in ALSA. 

aplay -l gives me:

I have the following audio-related modules loaded:

Any ideas of how to fix this? Thanks in advance.
