Buffer Underrun / Network Performance / Audio Playback

[Kevin Welsh]

I'm trying to test I2S Audio playback.

 

I've mounted a Windows network share like so:

//apps/MUSIC /mnt/music cifs noserverino,iocharset=utf8,username=media,password=        0       0

 

And playing with:

aplay -D default:CARD=sunxisndi2s /mnt/music/test.wav

 

With this result:

 

underrun!!! (at least 2.218 ms long)

 

Any ideas?

Perhaps it's related.

Audio is fine playing a locally stored WAV. Pulling a WAV from cifs share, playback is choppy. Copying a file from CIFS share is much slower than between 2 windows machines on the same network switch.

I think this is network cabling related.
