I'm writting an app that plays a special format and uses both the Alsa
seq and pcm interfaces to output MIDI and audio data together. I'm
almost done, but I've got one problem that is plaugeing me: I can't get
the two to stay in sync.
Basically, what I'm doing is using writei() to send frames
Peter,
This is very interesting. You mean this patch will enable passthrough
without the need for ld10k1, right? I will give it a try and let you
know what my results are.

Welcome to
The problem: the MIDI and audio start synced up, but after a while they
start to drift further and further apart. I've checked my stuff
exaustively to make sure that it's not the fault of my program, so I'm
figuring it is caused by me not setting up something properly in alsa to
make the two

It does passthrough using a standard PCM channel. No special TRAM tricks
needed.
Only works
I have tried the patch. I used ac3dec -C Sample51.ac3
as a simple test and it does work.
Great little piece of code many of us was waiting for a long time.

Two questions.
First: Is it possible to determine the maximum number of channels for a
sound card that is in use by another application? My method for
detecting the number of channels is:
- open the pcm
- use the hw_params API to determine the number of channels
But if another application has

Your patch works up to a point. It will only work on the Audigy, and not

The Audigy and Audigy2 do things slighly differently.
The L and R channels are reversed on the Audigy2, so I have compensated

I originally noticed this with ALSA 0.9.4, but it exists with ALSA 0.9.6 as
well.
When playing sounds and adjusting the left/right balance, left is right and
right is left. This is true in xmms as well as when using alsamixer.

The emu10k1 (and emu10k2) are quite interesting chip : they have many
