[SOLVED]

Edit: I did not have both alsa-lib.i686 and alsa-plugins-pulseaudio.i686 installed. Once installed, the sound worked immediately. Here's the fix:

1) Open a terminal window.
2) At the $ sign, Enter:
sudo dnf install alsa-lib.i686 alsa-plugins-pulseaudio.i686
You will need to enter the root user password.
3) At the $ sign, Enter:
exit
4) Restart Baldur's Gate.

OK, I realize Baldur's is only explicitly supported on Ubuntu, but I thought I'd give it a whorl on Fedora 23. This is a fairly late-model HP laptop with an intel core i3, 6gb RAM, plenty of hard disk space.

Sound in general works. I just played an MP3 using VLC and while the built-in speakers are a bit tinny, I could easily hear the audio.

lspci found two audio devices:
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Wildcat Point-LP High Definition Audio Controller (rev 03)

I believe Fedora 23 uses Pulse Audio by default but I believe I also have ALSA installed. I've been using Fedora since Red Hat 9, but don't assume I'm any kind of expert.

If you ran into similar problems and found a fix, please share any advice you have. Thanks in advance!

I suppose you have the 64-bit distro installed, so try adding the main 32-bit sound libraries.
I'm not familiar with Fedora (not anymore), but this should be the right command to input into root terminal:

That did the trick. I already had alsa-lib.i686 installed, but did not have alsa-plugins-pulseaudio.i686 installed.

Thank you very much!
