[TravelMate 8572G, Conexant CX20585, Speaker, Internal] fails after a while

[Giedrius]

After some time, about 30s speakers stop work, but headphones still work. After switching off to on sound card profile sound in speakers can hear again until 30s.

When speaker can't output sound, please run 'alsa-info' and 'pacmd list > pacmd-list.txt', then check if speaker could work or not. And upload the alsa-info.txt and pacmd-list.txt.
