Re: [Jack-Devel] latency: reducing buffer allocation
Ok, sorry
I found out the cause for this
http://mailman.alsa-project.org/pipermail/alsa-devel/2011-October/045173.html
The reason is OMAP McBSP2 having a 1280 words long buffer. Probably this
is something that can be overcome only by ALSA devels or the original
module devel from Texas Instruments... I'll ask
