I have installed windows 8.1 on my asus 1215N. The sound is good and no problem to listening with earphones and without it too. After than I have installed ubuntu 13.10. On ubuntu everything works well, but when I load windows 8.1, I haven't any sound with earphones. But the sound works well without inserting earphone in audio jack.
Same problem was on windows 8.0 too. I thought that it was windows fault, but as it seems it isn't so.. Can anybody help me ? Has anybody such kind of problem on dual boot system ? Thanks..
