if I put an ADC object in pd and I select the internal mix as registration source in the WINDOWS audio setup shouldnt pd receive this input and,for example write the input wave with TABWRITE?
that doesnt work for me
is there something wrong?

sounds like you need to set up your audio dev's in Pd or on the command line.

try 'pd -listdev'
and then you'll get a list of available audio devices. figure out which one you need and then type 'pd -audioindev <number>'
try that and you should be able to get audio into Pd...if you're not, it could be something wrong with your patch.

as audio input device i've only my soundcard
and....where should i type that 'pd-listdev'
i'm quite new of PD and i didn't know anything about typing something somewhere....

type 'pd -listdev' at the dos command prompt. when i start up pd, i go to the windows start menu, click run, and then type in cmd. the i change to the directory /pd/bin. the i run a file called pd.bat that has a command line to start up Pd with all of my default settings.

you might not need to set up your audio devices on the command line: some Pd versions have a setup menu within Pd that you can use to set your soundcard as the input device. if it's set up within Pd you should be ready to go.

don't know what were wrong but now it works
there is only one problem: even if there isn't any sound played
in my pc pd recive from the internal mix a loud loud noise
what's wrong?
i've only connetted the ADC object with a TABWRITE
couldnt be a problem with my patch

you sure you're not getting feedback from your pc's microphone input? happens all the time for me.

noise can come from a variety of sources. laptops can be especially susceptible: if you are running off a laptop, try running on battery power. if you are using a standard OEM soundcard that shipped with your computer, the ADC on the soundcard might not be of the highest quality and that could be part of the problem.

because you're noise is really loud, i would suspect a feedback loop somewhere. does the noise get progressively louder over time?

no,it remains always at the same loud volume.
and i havent any microphone connected.
i've tried to run my laptop on battery power but it doesnt change anything,
and yes,i have one of that lousy soundcard ....
