[HDA-Intel - HDA Intel, playback] Playback problem. Fast forward video playback.

I'm not sure about the reason but it occurred after a day of the laptop had been suspended.
Video files are played in a double speed with no sound but the problem disappears when HDMI is plugged in and there is audio from the HDMI source.
After I unplug HDMI there is only option in system settings "Speakers".
Volume toggle works fine, test was positive. Music playback is OK.
Made some modifications of PulseAudio files according to some solutions from the web.
