Indeed, I still see
haswell-pcm-audio haswell-pcm-audio: warning: stream is NULL, no stream to reset, ignore it.
haswell-pcm-audio haswell-pcm-audio: warning: stream is NULL, no stream to free, ignore it.
haswell-pcm-audio haswell-pcm-audio: FW loaded, mailbox readback FW info: type 01, - version: 00.00, build 77, source commit id: 876ac6906f31a43b6772b23c7c983ce9dcb18a19
haswell-pcm-audio haswell-pcm-audio: warning: stream is NULL, no stream to reset, ignore it.
haswell-pcm-audio haswell-pcm-audio: warning: stream is NULL, no stream to free, ignore it.
though sounds continues to work.
Thanks again,
