<div dir="ltr">Hi,<div> </div><div>I'm useing "pulseaudio.lib_pulseaudio" to record sound from a the internal source "alsa_output.pci-0000_00_1b.0.analog-stereo". But form some reason I'm only getting the sound from the right channel. I'm sure ?im missconfiguring something but I really don't know what could it be. I would appreciate any insight you might give me because I can't find any exmaples or tutorials about this theme.</div><div> </div><div><pre style="font-family:'Source Code Pro';font-size:14pt">samplespec = pa_sample_spec() samplespec.channels = 2 samplespec.format = PA_SAMPLE_U8 samplespec.rate = self.rate pa_stream = pa_stream_new(context, "peak detect demo", samplespec, None) pa_stream_set_read_callback(pa_stream, self._stream_read_cb, sink_info.index) pa_stream_connect_record(pa_stream, sink_info.monitor_source_name, None,) PA_STREAM_NOFLAGS)</pre><pre style="font-family:'Source Code Pro';font-size:14pt"> </pre><pre style="font-family:'Source Code Pro';font-size:14pt">And here I access</pre><pre style="font-family:'Source Code Pro';font-size:14pt"><pre style="color:rgb(169,183,198);font-family:'Source Code Pro';font-size:14pt;background-color:rgb(43,43,43)">def stream_read_cb(self, stream, length, index_incr): data = c_void_p() pa_stream_peek(stream, data, c_ulong(length)) data = cast(data, POINTER(c_ubyte)) for i in xrange(length): # When PA_SAMPLE_U8 is used, samples values range from 128 # to 255 because the underlying audio data is signed but # it doesn't make sense to return signed peaks. #self._samples.put(data[i] - 128) self._samples.put(data[i]) pa_stream_drop(stream)</pre></pre><pre style="font-family:'Source Code Pro';font-size:14pt"> </pre><pre style="font-family:'Source Code Pro';font-size:14pt">And here I get the audio everytime a need another sample:</pre><pre style="font-family:'Source Code Pro';font-size:14pt"><pre style="color:rgb(169,183,198);font-family:'Source Code Pro';font-size:14pt;background-color:rgb(43,43,43)">def getAudio(self): """get a single buffer size worth of audio.""" return self.__iter__().next()</pre></pre><pre style="font-family:'Source Code Pro';font-size:14pt">Thank you and hope to hear from you soon </pre></div></div>
