ALSA buffer underrun network audio
<p>I'm using Arch Linux ARM on an Olimex LIME2. Network speed tests between the device and NAS indicate > 450Mbps. I'm using an I2S Driver for audio output.</p>

<p>When playing 2 channel, 192kHz / 24bit material, I get the following:</p>

<ol>
<li>Playing from USB stick: good.</li>
<li>Playing from NFS share: buffer underruns between 7 &amp; 300 ms.</li>
<li>Playing from CIFS share: buffer underruns between 199 &amp; 215 ms.</li>
</ol>

<p>Where do I begin to track down the issue?</p>

<p>EDIT:
A. I'm testing with:</p>

<pre><code>aplay -D default:CARD=sunxisndi2s "/mnt/nfs/06 - Rosie 192.wav"
</code></pre>

<p>B. 96kHz / 24bit material plays without issue over the network.</p>

<p>EDIT:
PING results:</p>
