title: Android alsa snd_pcm_open default no such file o directory
body: <p>I try to implement baresip for Android, it uses custom <code>alsa</code> module for control audio devices.</p>
  
  <p>This module uses this code for open device handler:</p>
  
  <pre><code>err = snd_pcm_open(&amp;st-&gt;write, device, SND_PCM_STREAM_PLAYBACK, 0);
  </code></pre>
  
  <p>I tried to pass 'default', 'plug:hw:0,0', 'hw:0,0', 'hw:00,0' into this function. All results return error -2, that means no such file.</p>
  
  <p>I have two question. Is it any possibility to pass some string into this function for handling audio device correct? And in generally, is it real to interact with audio devices directly from jni using this function?</p>
  
  <p>Thank everyone!</p>
