Comment(by rsmith):

 I mentoned this to dsaxena yesterday but I'm adding it to the ticket.

 I have new EC firmware that speeds up the EC command processing by a
 minimum of 3x and normally by about 10x.  You can test it from


 If this helps to solve the issue then I'll add it into the the firmware
 and do an E13 release.

 Whats our audio frame size?  If its >= 512 bytes then a single frame of
 audio should be longer than most of the EC command processing duration.
