O meu sistema trava regularmente devido provavelmente ao driver alsa. O sistema de repente se torna inutilizável lento, embora a música continue tocando. Tentei enviá-lo para a equipe da ALSA, mas não consigo entrar no sistema de envio de bugs ... Este é um HP 8530w com um áudio HD Intel 82801I (família ICH9)
Feb 18 21:54:11 laptop pulseaudio[1980]: [alsa-sink] alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 404124 bytes (2290 ms).
Feb 18 21:54:11 laptop pulseaudio[1980]: [alsa-sink] alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.

Este é um palpite baseado em este post
no terminal, execute:
gksudo gedit /etc/pulse/client.conf
alterar linha nr. 27
de
;autospawn = yes
para
;autospawn = no
salve, feche, veja se ajuda
se não, reverta o arquivo client.conf para seu estado original e reporte-se
