I just installed Ubuntu 14.04 LTS, and I'm loving it. Only thing is that I'm having problems with my laptop's sound quality. It sounds empty, or hollow. I'm not exactly sure how to put it to words, but it's noticeably worse than it was on Windows 8.1. In fact, it was very much above average on Windows. I like Ubuntu but this sound quality issue is really annoying me, and even giving me a headache at times. It's not as loud as it should. If I put up the volume to 100%, my laptop's speakers start to resonate and distort, just sounds terrible overall.
I have an HP Envy TS-15 /w Altec Lansing, in Windows it had BEATS audio drivers.It has 2 front speakers, 2 subwoofers, and one speaker on the bottom of the laptop.
