Thank you very much. I'll implement it like that.

This is why we now have the "liba52" decoder which just happens to work
quite nicely o

Any AC3 or DTS takes some time to decode even with an external decoder.
The nice thing about them is that the standard tell us that they are fixed
latency decoders.
So, AC3 decoder will take a fixed amount of time to take a digital SPDIF in
and convert it to 6 analogue out's for your speakers.

Hallo List,
I want to receive midi events from my external midi keyboard.
Therefore I tried the seq decoder which comes with the alsa package.
This application creates a port and when I connect the midi port to this
listener ports, i can see the events coming from the keyboard.
That means, If i
Thank you very much. This sounds reasonably. I will try it.
Until now I hoped there would be a more easy solution.
But this is ok.

I do this by counting how many frames have already been written(from the
app), minus the frames still waiting to be written (from alsa, i.e. How many
frames are still in the sound cards buffer waiting to be output.)

Hi all,
I encountered a problem using PD (available at
http://www.crca.ucsd.edu/~msp/software.html) with the plugin layer of
ALSA (and a Midiman Audiophile + SBLive card here). This probably is a
problem with the PD source code, but on pd-list one is a bit at a loss
in fixing that problem. I can
Is there a way to determine the number of bytes/frames already played through
the DAC since last reset via snd_pcm_status in v0.9.x ?
Its possible in OSS via ioctl and in alsa v0.5.0 you can view at a element
"bytes" in sthe respective structure.
But how does it work in v0.9.x ?
