Hi Takashi, This is what I tried in the SOF driver: https://github.com/thesofproject/linux/pull/1513/commits And it seems to cause the system to hang when I stop the stream and I have no meaningful logs to pinpoint to the problem. Could you please have a look at the 4 commits that I have added to your series and let me know what I could be missing?
