i'm trying to play an 8ch wav file in a loop, 16bit 44.1, and it usually gives me an "underrun" error while playing the file at least once per loop.  this translates to a minor blip for between 30ms and 800ms where there is a jump in the audio.  the wav file continues to loop over and over, but usually one or two underrun blips per loop. 

i'm achieving the loop by doing this in terminal:

while [ 1 ] ; do aplay -D hw:audioinjectoroc /home/pi/Downloads/herefull8.wav ; done

if anyone has any ideas i could try, let me know!  i'm using a Sandisk ultra plus U1 microsd card on a raspberry pi 3B.

im brand new to rpi, everything i've done so far has been copying/pasting stuff i see on the forums, or something someone has advised me to do, i dont really understand this end of it, but all i need to do with the raspberry pi is simply loop this file and i should be all set. i feel like i'm very close!

thanks,

Zak
