For reference the sound card on my PanP7 is:
cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC272
Codec: Motorola Si3054
It has the most crappy output with ALSA sound server. The front mic used with a mic booster produces an extremely high pitched sound. I am sure it is capable of killing all bats in a 10 mile radius and driving all humans crazy or deaf or both.
The driver is meant for these following platforms. From /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz:

The problem is the regular sound output is extremely low. I can bet that if I put windows on this machine, the speakers will come to life. But that is just not happening with ALSA. The alternative is OSS, which I tried but had so many problems, I had to return to ALSA. I could install pulseaudio but pulseaudio has such crazy whims and fancies it is impossible to predict what will stop or start working next. It's a just a sound card, not some rocket science. Linux sound drivers just aren't up to snuff yet.
I have heard well not with this story things get a bit crazy over there that is why they made it so they have your real name.....
