Audio buffer underrun on imx8mm

asabil — Tue, 20 Aug 2019 17:08:54 GMT

Hi,

We are experiencing audio playback underrun issues on the imx8mm, whereas the exact same application runs flawlessly under imx8mq. The observed CPU usage is low.

Any pointers at how to fix/troubleshoot this issue further.

Thanks,

Ali

Hello,

Does this happen when you are reproducing a video with Audio? Are you reproducing Audio trought HDMI?

Best regards,

Diego

Hi Diego,

There is no video output and no HDMI either, this is a simple 2 channel i2s output to a digital amplifier.

Best,

Ali

Hello,

Are you using Linux or Android?

If you are using Linux, could you please pass me the gstreamer pipe-line that you are using.

Best regards,

Diego
