For recording movies you also need sound

Hallo Jaroslaw,
I think just by now I understand things better.
I thought the emu10k1 was used on the sb live card and on the audixy card.
But in fact the audixy chip is the next generation of the emu10k1.
emu10k1 is used in sblive whereas the audixy chip is used in the creative audixy

Hallo Group,
I was told, that the DSP code of the fx8010 needs to be upgraded to be able to
have the reverb effect available in midi(Controller 0x5b)
I cannot imagine how this could work because then the reverb would be applied
to all the notes.
But in Midi its possible to have reverb on single n
Hallo Jaroslav,
Now I have found a solution for my silent midi problem.
Therefore I updated the dsp code in alsa-kernel/pci/emu10k1/emufx.c
I added a slider called "Music Amplification" which is an integer between 0 and
16(in my box it is 100 in the mean time).
Now Midi's volume is ok.

Hallo Jaroslaw,
Yesterday I tried to load the soundfonts to load louder.
100% instead of 70% does not make much difference.
Then I tried to amplify the samples itself.
After some time i knew how to do this. But I realized, that the samples have
already been in the range from -32768 to 32767(optim

Hallo Takashi,
I am trying to understand the internals of my audixy card, but it is
quite hard for me, because i am a newbie to the audixy, and i am a newbie to
soundcard internals too.
I have been brosing through the source of the alsa driver to understand things,
but it goes very slowly.

Hallo List,
I have a problem with my mixer in the creative audixy card.
Even If I turn the slider of "Music" to maximum, the wavetable midi is still
far too silent. much more silent than playing pcm output.
But pcm output can also be adjusted when using slider "Wave"
But apart "Wave" and "Music"
Thank you very much for your help, Jaroslav,
I always appreciate your help

Hallo gang,
I have a problem with my mixer settings when listening to the sequencer(midi)

It is far to silent. I have to set my external amplifier to maximum
amplification to be able to hear the tunes in an normal loudness while hearing
the noise quite easy.

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

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 ?

It seems that midi output now works for the audixy card.
