I don't know how much help I can be, but I'll give it a stab.
First off, is the driver even being loaded? Run the following
commands and post the results for them:
$ lsmod | grep snd
$ cat /proc/asound/cards
The lsmod will show if the driver is being loaded (i.e., "snd" is
using "snd_hda_intel"). The cat will tell us what the kernel is
calling your sound "card", be it a separate card or built-in
chip. If the module isn't being loaded, you'll have to check
dmesg and /var/log/messages to find out what's going on.
If results of those commands look good, then it's time to start
looking elsewhere. You said you were using an mp3 file for
testing. What happens if you use a WAV or OggVorbis file? (The
"driver" spoken of may be the MP3 codec.) What are you using to
play the file? Are you running PulseAudio? If so, what does
pavucontrol show for available sound devices? (It should be the
name shown in the /proc/asound/cards file, above.)
That should get you started. I hope it helps.
