Is the lack of bass in sound also a mac issue ? It seems the sound in windows has more treble and bass, in general richer sound . I have found third party solutions like Boom! but i'm hesitant to install it
I think your question is a bit too general.
I do a bit of audio work on OSX, in fact, its the reason Im on this forum and using my elite book.
I don't have any issues with audio provided the application Im using is setup correctly, ok, so the internal speakers of the laptop are tiny and poor, but I wouldn't even bother comparing that across different platforms, as its poor to start with.
For the most of my stuff I will use an external USB sound card, which as stated above will run on CORE drivers from OSX compared with ASIO on windows, CORE is better for that purpose alone.
But even when using the internal sound card, HDMI audio.. once I have an application setup to how I like it, no issues.
What applications are causing you trouble with sound quality, audio production? watching Movies? or just general sound and youtube etc?
*I guess just to add, Apple audio drivers will be set up for apple hardware, they know the limited number of speakers that will be used on OSX (putting aside hackintosh which they do not support obviously) windows drivers have to allow for many more hardware configurations so may well allow for higher volume gains...
I just had a little read about "Boom" it appears it will work to boost your volume, nothing else, so you may lose quality in that, but be aware, that any safety limits put in place with AppleHDA will be overridden, push it too high, and bye bye speakers / headphones.
Provided you can set boom to an acceptable limit, and not be tempted to "test" how loud it will go, you should be ok with it if nothing else works.
Don't forget to check each application for its own volume settings / equalisers etc first.
