with options "snd-hda-intel=acer", it works quite well. There is a little problem of image that doesn't fill the screen in full screen mode. But I managed it involuntary, by doing a snapshot.
Nevertheless, the quality is below than in windows... there're a lot of big pixels. The image is less smooth.
And with "auto" instead of "acer", it's jerky.
I had already removed alsa-plugins-pulse, without obvious enhancement.
