device?<o:p></o:p></span></p>

<p>Hi, list. Today, I found a interesting "need". We have installed a
Access Grid client on a normal machine where the audio is a external
multifunctional microphone (concretly, a Yamaha PJP-25EUR: <a
href="http://www.gizmos.es/1828/audio-portatil/yamaha-pjp-25ur-microfono-multidireccional/">http://www.gizmos.es/1828/audio-portatil/yamaha-pjp-25ur-microfono-multidireccional/</a>),
this has a speaker and a set of microphones and, usualy, it is used for
Meetings Venues, etc.<o:p></o:p></p>
<p>Audio on Access Grid, works fine, but, I have to modify RAT to select the
audio device (in audio tab), because, by default, the audio device selected is
the sound card. On audio tab, I can select the default audio device to use on
RAT... so, I think that is interesting add an aditional option to AudioService
to select the audio device prefered.<o:p></o:p></p>
<p>I already modify the AudioService code tu add a new option, adding to the
end of __init__ function the next lines:<o:p></o:p></p>
<p>self.audioDevice = OptionSetParameter( "Audio device:",
audioDefault, self.listAudio)<br>
self.configuration.append(self.audioDevice)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p>Where, self.listAudio is a list where I want to store the differents audio
devices that has the system. And here is my doubt, how can I obtain the audio
devices installed on my system, like RAT show me? I thought to modify RAT to
permit storage the configuration, or see the code to see how RAT does it, but I
think that RAT is a compiled program (C or C++), right? I saw the "aplay
-L" and "aplay -l" commands, but I don't know if with this
commands I can do something (I don't, for example, if RAT detect the audio
names that this commands show me).<o:p></o:p></p>
<p>I know that I can modify the .RATdefault file to permanently save the
configuration. But I think that I'm going to see this in the future
and I thought that is interesting save the config with AudioService like Gains,
etc. I add this lines too on AudioService.py on WriteRatDefaults function:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p>ratDefaults["*audioDevice"] = str(self.audioDevice.value )<o:p></o:p></p>
<p>To save, the selected audio in AudioService window, to the .RATdefault file.<o:p></o:p></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><br>
<br>
<o:p></o:p></p>
<p>Sorry, as usual, for my bad English.<o:p></o:p></p>
<p>Thanks and Regards!<o:p></o:p></p>
