Hi Vinod,

We're creating a machine driver between the Maxim 98090 codec and Intel Edison in support of a realtime audio application.

So far, we have both record and playback working successfully. However, the latency on playback is higher than we would like. We've searched the alsa-devel messages but haven't been able to find a solution. We wondered if you might help us identify the best routing through the Atom's DSP for low-latency?

We noticed that a "low latency" path is referenced in the Merrifield DPCM controls file (controls_v2_dpcm), but it doesn't appear to be implemented yet. What do we need to do to set up the SST to use its low latency paths? Would this be similar to configuring a media path (sending the command MMX_SET_MEDIA_PATH, SST command 119)?

Thanks, David
