Comments
@Jiangxinx @ClarexZhou |
Behavior is different on CML. Environment Firmware Repo :https://github.com/bardliao/sof/tree/whl-daliy-20190422 Topology: Same as above SOF repo |
@keqiaozhang can you please help to verify if this issue can be reproduced on I2S platform? thanks! |
@wenqingfu , I tried to reproduce this issue on GLK before, but it's blocked by #828 , HDMI is not working.

Clair's bug is narrowed down to codec issue. As per discussion we can lower its priority. |

Can we have confirmation that the two outputs work in isolation and the issues only show up when the two outputs are used concurrently. |

@libinyang CML issue is split and track on #874 |
quote @keqiaozhang in thesofproject/sof#1354 (comment) , "these PRs can fix issue #854" |

@wenqingfu Ack, looking at multiple multi-stream cases, I can take a look at this as well. |
Analyzed and moved to firmware as thesofproject/sof#1526 We can keep this open until FW confirms. @Jiangxinx please add more info to the FW bug if nocodec test scenario can be repeated on other platforms than APL |
I could not reproduce the issues with nocodec mode on WHL. But nocdec mode issue on APL seems clear. |
@keqiaozhang Can you confirm this is fixed now and close the bug if yes? The bug is now fixed in firmware ( thesofproject/sof#1526 ). |
Issue not reproduced with test recipe as below, so close it. Test recipe: |
Describe the bug
