Can't hear midi files on 8510w

Just bought an 8510w and immediately run into a problem of playing midi files. I'm using MPC to play all media (I have no WMP installed but Windows media runtime 11 is present, along with K-lite Mega Codec pack). MPC sees and plays a midi file--silently. The slider's moving, time's counting down--not a squeak.
I have installed UAA bus driver recommended on the HP site. It is listed as responsible for MIDI playback on the Properties tab of SoundMax HDA. Does its job poorly, though.

Anyone, any luck with midi playback? Or am I just missing something?

 

hmm, try vlc media player? Thats all i can say to help though. Sorry.

 

Thanks for a very prompt answer.
Yeah, I could hear midi files with fully autonomous players like VLC or AIMP2. But I hate redundancy. I'm using MPC for all the media and I wanna stick to it.
For those who may come across this problem--
Well, maybe they won't. My problem came with a stripped down XP (~200Mb, hand-made using nLite). I left just WMP 6 support.
I ran dxdiag and found out that dls files were missing in the registry. So I took gm.dls, along with a couple of registry keys from a full XP version (my friend's computer)--and the trick was done.
