Hi I've installed pothos again and I've set C:\Program Files (x86)\gnuradio\etc\gnuradio\conf.d\gr-audio.conf and changed from auto to portaudio:

[code]

This file contains system wide configuration data for GNU Radio.

You may override any setting on a per-user basis by editing

~/.gnuradio/config.conf

specify which audio module to load, or use "auto" to have the system

select one. Valid choices depend on your OS and which modules

you've installed, but typically include:

auto, alsa, oss, portaudio, jack, osx, windows

[audio]

audio_module = portaudio [/code]

but it still wan't to use Audio source arch: windows but I know I've setted the right config? see here: gnuradioportaudio

PS: I have some problems with UDP Source/sink it always trows this error: udp

Thanks for Anwsering and Best Regards

Ahh... gnuradio constants.cc is loaded full of un-escaped slashes and hard coded paths. I wouldnt count on it finding the conf file at this rate...

PS: I have some problems with UDP Source/sink it always trows this error:

My guess is that WSAStartup() is not called. Any socket API will not work.

OK, so more patches.

guruofquality commented 8 years ago

Actually maybe there is some hope for finding gnuradio.conf...

It looks like gnuradio will look for the config file in APPDATA/.gnuradio/config.conf
On my system APPDATA is C:\Users\Me\AppData\Roaming.gnuradio\config.conf

Although this is still not working for me... references below

app data path

const char *appdata_path()
  {
    const char *path;

    //first case, try HOME environment variable (unix)
    path = getenv("HOME");
    if(path)
      return path;

    //second case, try APPDATA environment variable (windows)
    path = getenv("APPDATA");
    if(path)
      return path;

    //fall-through case, nothing worked
    return tmp_path();
  }

_sys_prefs_filenames

// Find if there is a ~/.gnuradio/config.conf file and add this to
    // the end of the file list to override any preferences in the
    // installed path config files.
    fs::path homedir = fs::path(gr::appdata_path());
    homedir = homedir/".gnuradio/config.conf";
    if(fs::exists(homedir)) {
      fnames.push_back(homedir.string());
    }

My guess is that WSAStartup() is not called. Any socket API will not work.

Try this: using the import block, import socket. Importing the socket module from python may also call WSAStartup() and cause the UDP blocks to work.

guruofquality commented 8 years ago

Update, found the issue with the conf file.

Bug 1) the unescaped slashes in the constants file. They are actually correctly escaped, then the file is overwritten again, without correct escapes.

Bug 2) Because of bug 1), the configuration read code refuses to search any paths, even APPDATA.

The workaround (before recompiling and new installer) would be to hide this python statement somewhere. Possibly edit gnuradio-companion.py and add after the gr import statement. (Modify for your username.)

gr.prefs().add_config_file('c:\users\<yourUsername>\AppData\Roaming\.gnuradio\config.conf')

veso266 commented 8 years ago

It aphers that GNU Radio registers config because when I delete config.conf it won't run (no error message)

I edit gnuradio-campanion.py like that:

pythongnuradio

but it still want to use Audio source arch: windows so I don't know how to best check if portaudio is used regarding UDP Source (if I import socket the error is the same as without it)

Thanks for Anwsering and Best Regards

guruofquality commented 8 years ago

Work around update

Because GRC generates the code and executes in a separate process, the line gr.prefs().add_config_file('c:\users\<yourUsername>\AppData\Roaming\.gnuradio\config.conf') should be added to this file instead so it becomes part of the generated code C:\PothosSDR\lib\site-packages\gnuradio\grc\python\flow_graph.tmpl. Sorry about the confusion.

Audio update

I fixed constants.cc in the gr-runtime project, the fix will be in the next build. For reference see https://github.com/pothosware/gnuradio/issues/22

Screenshot

C:\Users\User\AppData\Roaming.gnuradio\config.conf

[audio]

audio_module = portaudio

Using a audio source to fft sink. port audio worked right away. and its very talkative. Lots of verbose like this, and the verbose from the screenshot:

before paHostApiInitializers[0].
after paHostApiInitializers[0].
before paHostApiInitializers[1].
PA - PlatformId = 0x2
PA - MajorVersion = 0x6
PA - MinorVersion = 0x2
PA - PlatformId = 0x2
PA - MajorVersion = 0x6
PA - MinorVersion = 0x2
PA - PlatformId = 0x2
PA - MajorVersion = 0x6
PA - MinorVersion = 0x2
PA - PlatformId = 0x2

UDP issue update

Ignore my previous comment. This will be fixed in the next build, here is the patch with an explanation of the problem: https://github.com/pothosware/gnuradio/issues/23

guruofquality commented 8 years ago

Update: I believe this issues are fixed. I working on a build with MSVC 2015, and I will close out this issue when new installers are available. Thanks.

guruofquality commented 8 years ago

Thanks for all of the feedback and testing. New installers are up with the patches. I am closing out this issue. Please open a new issue if the problem persists, or you find a new issue. Also note that you will still need to set the config.conf to use portaudio. But of course, it will work now :-)

In summary:

Announcement: https://groups.google.com/forum/#!topic/pothos-users/1HOKTbOPHpo
The socket issue is tracked here: https://github.com/pothosware/gnuradio/issues/23
The constants issue is tracked here: https://github.com/pothosware/gnuradio/issues/22
