    copied!<p>I'm trying to use pulseaudio to play the contest of a vorbis-stream but are hitting problems. Basicly I'm told that:</p> <pre><code>‘pa_simple’ was not declared in this scope ‘pa_simple_new’ was not declared in this scope ‘pa_simple_write’ was not declared in this scope </code></pre> <p>Some code are shown below:</p> <pre><code>#include &lt;pulse/pulseaudio.h&gt; </code></pre> <hr> <pre><code>pa_simple *s; pa_sample_spec ss; ss.format = PA_SAMPLE_S16NE; ss.channels = 2; ss.rate = 44100; s = pa_simple_new( NULL, // Use the default server. "Fooapp", // Our application's name. PA_STREAM_PLAYBACK, // Playback NULL, // Use the default device. "Music", // Description of our stream. &amp;ss, // Our sample format. NULL, // Use default channel map NULL, // Use default buffering attributes. NULL, // Ignore error code. ); </code></pre> <hr> <pre><code>while((samples=vorbis_synthesis_pcmout(&amp;vd,&amp;pcm))&gt;0){ int j; int bout=(samples&lt;convsize?samples:convsize); cout &lt;&lt; "D" &lt;&lt; endl; for(i=0;i&lt;vi.channels;i++){ ogg_int16_t *ptr=convbuffer+i; float *mono=pcm[i]; for(j=0;j&lt;bout;j++){ int val=floor(mono[j]*32767.f+.5f); *ptr=val; ptr+=vi.channels; } } cout &lt;&lt; "E" &lt;&lt; endl; #ifdef PulseAudio pa_simple_write(s,convbuffer,2*vi.channels,NULL); #else fwrite(convbuffer,2*vi.channels,bout,output); #endif vorbis_synthesis_read(&amp;vd,bout); cout &lt;&lt; "F" &lt;&lt; endl; } </code></pre> <p>It's probably some simple error, but if anyone could point me into the right direction, that would be great!</p>
