The only way to support Midi on that system is via software midi. There
is no hardware midi support directly to the system (no place to plug in
midi devices), except through USB or possibly integrated in a docking
system. To get Midi support for Linux, use Timidity
(http://timidity.sourceforge.net). This will convert midi sequences to
pcm audio tracks.
I personally can't translate the specs listed, but from what I can tell,
the system should have a Line-in, Mic-In, and HP-out jacks, along with 4
internal speakers (nothing indicating surround sound). It does have
SPDIF out, and I would assume that will allow surround sound if hooked
up to a digital receiver, as SPDIF is essentially a digital
pass-through. The codec itself only has two DACs, which could be
configured between the headphones and speakers to do a quasi-surround4.0
setup, but based on the chip diagram would take some additional
And I'm sorry I dropped the ball in helping here. I wish I could spend
more time on Alsa, but economics forces me to have a full time job doing
non-alsa work at this time. Bad excuse, I know.
I'll try to get my test board working again this week, and I'll even
download the Windows drivers for your system to use as a baseline for
comparison. No guarantees, though.
