Glad you got it figured out. I suspect "High Definition Audio" is the name of the internal sound card of the laptop. Mine is called Realtek High Definition Audio.
Maybe check out the mp3 clinic where people post things to get other people's feedback.
Thanks very much for your suggestion I truly appreciate it. Now allow me to give you a good tip. Most musicians now days (you may not be included) are of the mindset that more is better in every way. More instruments, more effects on top of each other. Music has become extremely mechanized since the invention of the synthesizer. When you listen to recordings you hear a pristinely done musical arrangement with every instrument in it's "perfect" place. Young musicians have been brainwashed into this mindset, whether it was intentional or not, personally I believed it simply morphed in that direction.
So, after spending decades in production, I would advise any home recording affectionado just the opposite of what the current mindset is towards recording perfection. If I was arranging your song in a studio setting I'd advise you to keep it simple, don't overdo anything and allow your talent to shine through and not all of the effects and precision that most try to achieve. By doing so, one's own personal talent or the song's merit will become more evident. The more RAW your production is the better, raw music is alive is it not?
The Rolling Stones are a great example. Except for Jagger's voice it is and always has been one of the most untalented musical groups (in my opinion) in history. I can go through each member's talents, or lack of it, but I won't bore you. So why are they still the No. 1 band in the world -tied with the Eagles - the answer is their rawness there lack of sophistication and this is why people love them. Ask any person "why do you like the Stones" and they will say "their music sounds live on records."
So if you want to be successful my friend do what everybody else isn't doing !
Again, thanks for your input and I hope the above may tickle your musical thought process ! Good luck in the New Year and I'm here to help if you need it.
