Hello Maintainers, I have a question regarding XRUN handling. After an XRUN is triggered, userspace generally calls TRIGGER_STOP followed by PREPARE and TRIGGER_START. In the PREPARE stage, we are currently not sending the ALSA ring buffer (physical address, rate, format, etc.) IPC to the DSP but instead doing that in HW_PARAMS which is causing bad audio after XRUN is triggered. I was able to resolve the issue by moving the IPC to PREPARE, which fixes the XRUN problem and results in good audio even after an XRUN. I have also observed a similar approach in Qualcomm drivers, which I assume is for the same reason. Is moving the IPC to PREPARE the correct approach for handling this issue? I would appreciate any insights or guidance on whether this is the recommended way to handle XRUN recovery. Thanks,
