I have DOLBY speakers on Lenovo z50. I dont have any real problem with my laptop speaker, there is difference in sound quality on same hardware but differnt OS - windows 8 and Ubuntu. sound quality is good on Ubuntu but it is great with all minute details on Windows 8, is there anything we can do about it?
the difference is:
- sound is more louder on Windows 8
- background sound is more clear and loud with all minute details playing on Windows 8
Is it because Windows have better driver support?
Update:
Laptop Model: Lenovo Z50 59-429623
Speakers:
Integrated stereo speakers with Dolby® Home Theater
