Hi,
I have a Pavilion dm4-3055dx and the audio level is fluctuating (it seems like it's trying to normalize the sound which is annoying when something is quiet). I guess it is basically like the problem with the dv6 and dv7 (http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio/Beats-Audio-fluctuates-on-dv6-70XX-amp-dv7-70XX-model/td-p/1841707). I tried to install a new driver every now and then since I got the laptop but it never helped. Is that the same problem as for the dv6 and dv7 and is HP aware of that?
