Ranjani,

Commit 14ca1fa3d5a1d7b40bcbfc36d66b0ad96198a21c doesn't do anything on PCM params. It forces L1 exit for Host DMA only after trigger stream start.

Hi All,

Audio playback seems to be broken on my up squared due to the this commit: 7c281d3d894ce8e9b9ea5a6a314c5c9d8e631d3e.

can you try a quick git bisect, the commit is a merge and doesn't provide much information on which of these patches are problematic.

commit 14ca1fa3d5a1d7b40bcbfc36d66b0ad96198a21c Author: Tomasz Lauda tomasz.lauda@linux.intel.com

This one seems to be the culprit.

...

I get "unable to install hw_params" error when I start aplay.

Please find attached the dmesg log below.

Thanks, Ranjani

I've logged as issue on github to track.

Confirmed on UP2. Update some new log to the github issue.

Thanks Xiuli
