Hi
I am using alsa 0.9beta12 and a via686a soundchip which works fine.
But aplay seems to have a problem for me:
Everytime I start aplay with a sound file, it gives a SEGFAULT!
This is what gdb says:

I have a snd_rawmidi_t. And I want to know what client Id it will have
in the other end.
For example my first rawmidi is card 2 device 0. And that is client id
80:0 but how do I look
that up in the rigth way?

I have just done some work on the alsa-howto wiki for the cmipci card.
I intend to use this as the template for all the other cards. I appreciate any
constructive criticism.

You have a program that uses the sequencer to read MIDI data. That's

I don't. I intend to wait for (and contribute too, if I can) what I
consider the correct solution:
a) sequencer genuinely split into:
1) a router/multiplexer
2) a scheduler
b) sequencer moves into user space

Paul,
I must admit that looking at the current state of things a move or migration
of the ALSA sequencer to user space (either fully or partially) would be a
good thing.
At the time I came up with the ALSA sequencer we were talking about alsa
0.0.12. It was 1998, yet only 4 years ago and my de
Frank -
thanks for writing. I don't want to suggest for one moment that there
is any "blame" to be attached to the current sequencer design. None of
us knew what we know now, and as you point out the hardware state of
affairs has changed considerably.

i used mozilla to take a look again. i had originally suggested making
the font of the main "text" table larger. i still think is a good idea
