[Alsa-user] Problems with MID output

[Felipe A. L. <fel...@gm...>]

Hello guys,

I never could see pmidi or playmidi working on ALSA unfortunately. But
I thought that it was my sound card's fault, and I never cared to
track down the problem. So, as you can see, I have no experience with
this on Linux.

But now I bought a Genius Sound Maker Value 5.1 (Chipset C-Media
Electronics Inc CM8738) and I *think* it should support some sort o
MIDI playing.

Now, again, I'm not sure it supports it, although I think the problem
is my configuration. I'd like to know if there's a way to know if it
supports or not and how to activate its support. Also, in the mixer,
there's a Synth entry.

I'll give you whatever maybe interesting to know about this card:
